Video Transcript for Transmission Cooler Installation - 2013 Dodge Grand Caravan

Today in our 2013 Dodge Grand Caravan, we're going to review and install the Derale transmission cooler part number D13503. Now to begin our install, we're going to open up the hood. We need to remove the front fascia to gain access to a location to mount our transmission cooler. To remove the front fascia, we'll start here at the top, removing the 4 fasteners. The 2 on the outside will be screws, or bolts, and the 2 on the inside will be push-pin fasteners. We'll go ahead and remove the push-pin fasteners first using our flat blade screw driver, prying the center of the fastener up and then removing it.

Once we have both of those out of the way, we'll then go ahead and remove the 2 bolts. Next, we'll move to the wheel well. Keep in mind that each process we do here in the wheel well we will repeat identically on the opposite side. We're going to go ahead and start here on the driver's side. Now, to gain easier access to the fasteners, rotate the wheel in so that we have easier access to remove the 2 screw fasteners here in the fascia in the wheel well, and the one bolt fastener that secures the fascia to the fender. Next, we're going to move underneath. We need to remove the push-pin fasteners that secure the lower fascia to the lower cooler support.

Then we'll have one additional fastener that secures the fascia to the wheel well. Now, these are push-pin fasteners, or commonly known as Christmas trees. We're just going to use our trim panel tool to remove them. Once we pry the 5 fasteners out and set them aside, while we're underneath the vehicle, and because this model is equipped with fog lights, we're going to go ahead and disconnect the manufacturers wiring for the back of the fog lights socket. To do that you simply press on the connector lock and then remove the connector from the back of the socket. Now, with all our fasteners removed, it's a good idea to get an extra set of hands to help remove the front fascia so it doesn't fall off.

Starting on one side, we'll go ahead and pull the fascia out away from the fender; releasing any fasteners underneath. Then, we bring the fascia away from the front of the vehicle, and set it out of the way to be reinstalled later. Now with the front fascia out of the way, it exposes our transmission lines as they go in here to the upper portion of the radiator, or condenser. Once we identify them, we need to figure out which side is going to be our hot and cold, or pressure and return. To do this it's recommended warm the transmission up while feeling the 2 lines. There should be a temperature difference.

As we warm it on up, we notice that the upper hose, or line, is the hotter of the 2. So, the bottom one will be our return and the side that we'll connect to the new Derale transmission cooler. Now with our fascia out of the way, we're going to go ahead and pre-assemble our transmission cooler hoses onto the transmission cooler. Here we have the protective covers that we can remove from the transmission cooler nipple, and our hose. Now to make it easier to get the hose onto the fittings of the cooler, we're going to go ahead and dip the hoses into some transmission fluid. This will give it a little lubricity, and easier to put on. We'll go ahead and start here on the one side, working the transmission hose onto the fitting. Now once we have that side on I'm then going to take 2 of the hose clamps and slide it onto the hose so we can secure it after we have the second side installed. Installing the second side is the same process as we did for the first side. We'll dunk our hose, and then slide it onto the fitting. Once we have both hoses securely onto the cooler, we'll go ahead and take our clamps, slide them up into place, and tighten them down. Now we have our transmission cooler pre-assembled. Next, we'll go ahead and identify where we're going to mount the transmission cooler. We're going to run our fasteners through the pre-attachment points here on our cooler into the back of the steel bumper. However, since we have minimal clearance between the back of the bumper and the A. C. condenser, we're going to go ahead and remove the bumper to make it easier to attach our cooler. Holding our cooler in place, we'll use a paint marker and mark out where it's going to sit on the bumper. Then we'll go ahead and set that aside, and begin to remove the fasteners that secure the bracket and bumper so that we can set the bumper aside and pre-drill our holes. To remove the bracket there are 2 fasteners. One here at the upper corner support and one down at the bumper. Set those fasteners aside. Now we've got 3 more large fasteners, and 1 small one. Now once we have all our fasteners removed here on the passenger side, I can move over to the driver's side and repeat the same process. Note: Before you remove all of your fasteners, you want to make sure you disconnect the air temperature sensor from the bumper. To do that, you'll remove the push-pin fastener by prying out on the center of the fastener and then removing it completely. This will just release it, setting it aside for re-installation later. Now with the bumper off, we're going to go ahead and pre-drill our hole. The reason we're pre-drilling the hole is because this is a hardened steel bumper, so it can be difficult to get your hole started. I recommend you use a step-bit process starting with a smaller filer bit, and then working your way up to your final size that'll be recommended for whatever fastener you use. We're going to use a self-tapping fastener. Next we'll go ahead and identify how to remove the manufacturer's transmission cooler line from the radiator. All right, now with the cooler secured to the bumper before re-installing, we're going to prep the manufacturer's line. Go to the manufacturer's line, take the black plastic cap and slide it back. This will expose the locking clip that holds the manufacturer's line into the cooler. We'll go ahead and use a small screwdriver, or needle-nose, to gently remove the clip from the fitting. Once we've pulled the clip out, we can wiggle the line free and pull it out of the cooler. Now, once we have it out of the cooler I'm actually going to go ahead and put it back in just to save any fluid that could come out. Now that we know the manufacturer's line is prepped, let's go ahead and reinstall the bumper. We'll just reinstall it with the manufacturer's fasteners that we removed. Now once the bumper is back in place we'll go ahead and take the hose that we installed on our new transmission cooler, route it, mark the length of the hose, and cut it. Keep in mind when routing your hose, if you have to make a large bend or turn as we do here, we're going to make them big, sweeping bends or turns to not kink the hose. Next, we'll take the Derale snap-in adapter fitting part number D13035, and install it onto our cut hose. Once we have it installed on the hose, we'll go ahead and take the clamp provided with the install kit to secure the fitting to the new hose. Now we can remove the manufacturer's line from the cooler and install the new fitting and hose. As we pull the manufacturer's out, we'll go ahead and slide the new one in. We'll make sure it's firmly pressed into place, and then we can reinstall the locking clip to hold it in position. Once it has the locking clip on, I'm going to pull on the hose just to make sure it's locked in properly. Once we know it's locked in, we can reinstall the cap. Now we'll take the remaining hose that we cut from our Derale cooler, route it to the manufacturer's line, and cut off the excess length. Go ahead and slide the hose clamp on, and then dip our hose into the transmission fluid to provide lubrication, so we can slide the new hose directly onto the manufacturer's line that we removed from the manufacturer's cooler. Once we have the hose in place, we'll go ahead and tighten down the clamp to secure it. Now with all our connections made and secured, I recommend to secure the hoses and lines as necessary. We're just going to use some zip-ties. Once we secure it, we'll cut off the excessive zip-tie to get it out of the way and clean up our install look. Once we've completed that, we're going to go ahead and test for leaks. To test for leaks we'll repeat the same process we did warming up the transmission to locate our hot and cold side. We'll make sure we bring the transmission up to operating temperature. Now once we've verified that we don't have any leaks, we'll go ahead and reinstall the temperature sensor, and front fascia with all the manufacturer's fasteners. Now with everything reinstalled and checked for leaks, this will complete the review and install of the Derale transmission cooler part number D13503 on our 2013 Dodge Grand Caravan. .

It was a pretty straight forward installation. I did have to remove the battery and tray as the factory spring hose clamps were positioned such that I could only get at them from the top, couldn't squeeze the clamps from a below angle. Thankfully I watched their video before ordering to see I needed another length of hose to finish the install. Took about 3 hours and seems to work well. 568120

This transmission cooler fit perfectly behind my grill. I mounted it on brackets in lieu of a direct mount on the radiator. I’m glad you recommended the GM adaptor hose fitting as my application would not work with the Insta-Dapt which was not compatible. Works great towing my 4,000# trailer in this Florida heat. 524895

I decided to install the Derale 8000 on my 2005 Honda Odyssey with 57,500 miles as an investment in hopes to prolong the life of vehicle. The Derale 8000 series came with complete with all the parts needed for my installation. I had zero trips to the auto parts store. I'm not a mechanic but the installation was fairly easy. The videos provided by etrailer was extremely helpful and gave me confidence to do the install. The hose, provided, fits perfectly into the factory Honda hose outlet from the radiator. Also, as mentioned by other reviewers, installing the hose is a difficult even with transmission fluid to lubricate. However, I had a hard time trying to secure the cooler, due to the tight space between the condenser and radiator. A long cutting pliers/scissor would help and a lots of patience. Install with confidence! Thanks Etrailer for the awesome instructional videos! 391814

Good product easy install! had to order extra 5 feet hose to fit my 2012 Sienna. I bought it for towing my RV without damaging my transmission. Don't have any info if it really helps lowering my trans temperature but pretty confident about it. 528992

The cooler was exactly as described. The best part was the instructional videos showing 2 different installs on Honda Odysseys. They each installed it in slightly different ways so I was able to use both videos to get the job done right. I wouldn't have felt confident in doing this job myself without etrailer's assurance that I was getting the right part. 443108

this product is of good quality and a good size to make a big difference on the cooling of the transmission, so much that when its spring winter or fall, when i'm just driving around town the engine wont get to operating temperature until i drive for about 30 min. It's an easy fix to just use a piece of cardboard over the transmission coolers when its cold out and your not towing. Then the temp comes up as usual. When towing just make sure to keep the bugs out of your rad and coolers. Towed my trailer through the mountains where my truck over heated last year and had no problems this year. truck is a 2012 ecoboost 3.5l f150. Needed a few fitting but the local farm supply store had them, i hooked it up in series behind of my stock cooler, the fluid goes from the rad to this cooler then the stock cooler. 568743

Installed this in a 2005 Nissan Pathfinder. Fit is excellent. I wanted to remove the factory radiator connection as this is a common point of failure allowing coolent to enter the ATF. This is plumbed from the transmission to the factory cooler, then to this new cooler, then back to the transmission. The only thing extra I had to buy was a 3/8 double barb to connect to an existing hose. This cooler adds about half a quart of ATF to the system. I can't speak for any temp drops as I don't have a temp gauge installed yet. 101344

Hardest part of the installation was confirming which of the lines was the hot and which was cold. After that, installation on my 2005 Pilot was easy. Just follow directions or find a YouTube video. Tranny coolers are a must if you're planning on taxing the transmission by hauling/pulling or doing lots of hill climbing with a load in the truck/SUV. Shipping was super fast and customer service follow up on my order was great. I will absolutely buy all my trailer stuff from these guys. 291142

I ordered a transmission cooler for my '09 Tahoe that, even with the small cooler for the towing package, just could not handle the California/Oregon mountains. I had my trusted mechanic install it (he has much greater expertise than I). I've just returned from an identical trip over those same mountains. What a difference! Instead of topping out at 230 degrees (dangerous), I topped out at 183, only 13 degrees from normal operating temp. I ordered the cooler and installation hardware. It's been awesome not to have to worry anymore about transmission burn out hauling my trailer that is 25% BELOW advertised towing capacity of this vehicle. Kudos to etrailer for offering such great products! 302744

I installed this transmission oil cooler in my 2003 Honda Odyssey a year ago because this model van is known for its transmission overheating and failure issues. This cooler is more than adequate for the task. Plus, installation was a breeze thanks to the helpful video. I wish I would of have installed this cooler years ago. It would of saved me a tranny rebuild. 246760

Fabulous. For a 2002 Odyssey don't remove factory fittings from RADIATOR. Remove hoses from steel tubes that come off the radiator and use a double male fitting from the hardware store for the return hose. To make life really easy, download a copy of Honda's installation for Factory Cooler to figure exactly where the return lines are. Rip off the bumper. Get er done. 1 hr. The whole car drives different. Smoother. Quieter. 39178

Jeep Liberty

Installed the product today. My installation is pretty unique on the Jeep Liberty CRD. This vehicle has a pusher fan in front of the stack of heat exchangers (Condenser/Trans cooler, intercooler, radiator), so the "zip tie" installation is not an option. Also, the stock trans cooler, which is the bottom 1/4 of the A/C condenser, has a different type of fitting on it. Product seems to work as intended. Hoses were a bit hard to get onto the barbs, even with a little transmission fluid as a lubricant. 47086

Excellent quality and build. I installed this in a 2003 Chevrolet Avalanche. I wanted a factory look installation so I mounted the bottom of the cooler in the factory bracket located mid way and made a bracket to mount the top of the cooler. I mounted it with the hoses downward so they will not be visible from the outside of the car. See pics for details on the brackets and mounting. 176500

Put this trans cooler on a 05 Odyssey because without it they have transmission problems and every automatic needs one realistacly. Heat kills transmissions. This one has enough volume for this size vehicle and keeps it 30 degrees cooler then engine temp. Ran it from the transmission to the radiator and out to the cooler and back to the transmission. This helps with cold weather warm up temps while dropping the normal operating temp to a better operating temp for the transmission. Overall I am highly satisfied and it is providing longevity to my vehicle. 244199

2007 Chevrolet Silverado

I have a 2007 Silverado Classic w/ 4.8L and was somewhat nervous about buying the tranny cooler because I have never done this before, but honestly, it's pretty self-explanatory. I bought the 8000 series I also used GM adapter D13035 and it fit easily in the "out" position of the radiator. I placed the cooler in the very front of the oil cooler so that it would get 100% air. However, because I did not want the ties to go through the oil cooler and then the radiator, there is a bottom bracket that goes across <--------------> the oil cooler and I cut slits into it and made holding bracket for the trans. cooler so now it is about an inch in front of the oil cooler. This will allow maximum cooling because air can circulate all the way around the cooler. I'll post some pics when I can. -Art P.s. Had to buy about 3 more feet of hose, but not too bad of an install for someone who hasn't done this before. 31532


Comments

I am installing this on a 2007 Silverado, new body style, V6, 4.3L . I assume the trnasmission return metal line will have to be cut and the rubber line coming from the cooler will fasten to it? Is there an adapter for this or just a standard hose crimp?

-- comment by: Derek - 02/10/2014

You will connect the new cooler input to the OEM cooler output using an adapter, part D13035. From there output hose on the new cooler will fit over the barb on the metal OEM return line and use a hose clap to secure. We have a video of this kit being installed on a 2011 Suburban, the install will be very similar on your Silverado.

2010 Jeep Liberty

Thanks for shipping so fast. the response time was impressive! Below is a picture of the install of my Derale trans cooler (13503) installed in my 2010 Jeep Liberty. I did not install with the inlet/outlet on the bottom due to thinking that with a plate and fin type cooler air might get trapped in other end. I mounted it horizontal and put the inlet flow on the bottom to assure that any air gets purged. Odd thing about this trans is that there is a bypass valve on the lines that is thermally operated. The flow to the coolers is bypassed until a specific oil temp is reached. Then flow is allowed to go to the cooler(s). This is done because the trans cooler is completely independent of the radiator. There is no thermal exchange between the trans fluid and the engine coolant. With the transmission fluid bypass valve in operation it is not possible to reduce trans temp below a preset level (or nearer ambient temp) because the thermostat valve simply turns off flow to the cooler(s). In a conventional setup the coolant flows all the time and there is no by-pass. Trans fluid is kept from dropping in temp by the engine coolant which will actually put heat into the trans coolant if the engine coolant is warmer. Chrysler has no thermal exchange with the engine coolant so they thermostatically control flow to keep the trans from operation at a too low temp. In short, in my vehicle I can’t reduce the trans temp below the thermostat setting, But I can assure that the temp of the trans can never be too hot. I also mounted the trans cooler on brackets I made. I was uncomfortable pushing the rods thru the radiator and the air conditioning and factory trans cooler. The added mass of the Derale trans cooler may have been a little too much clamped onto the radiator. I tapped into the original hose with a 3/8 double barb fitting and double clamped all connections. Also below is a exploded parts view showing the by pass valve on the trans lines which directs trans fluid back to the trans and by passes the cooler(s) until the trans gets to a specific temp. It is item #3. 97702

Nice discussion John, thx. Did you have over heating problems prior to cooler install. I have a 2011 Liberty that overheats any time I use it off road on hills in the summer....the Jeep dealer told me that they all do this...I wonder if its actually the bypass thermostat?

Hi Don, My Jeep has never overheated either engine or trans. I have never heard of them being prone to overheating either. If you suspect the inline thermostat on the coolant line I think that would be easy to check simply by feeling the lines and seeing if the line is returning hot trans fluid without going up front to shed some heat. I added the cooler because I put a trailer hitch on and just wanted to make sure that the trans would stay in the proper operating temp range. Are there a lot of bugsdebris in the trans or engine radiators? Is the thermostat cycling properly? Any pinched hoses? If the engine coolant is too hot it may be a pinched hose. Check the temp of the inlet hose versus outlet hose while the engine is running. If the return line is at the same temp as the outlet hose the radiator is not shedding the heat adequately. Cooling problems can be a little tricky but a little detective work can usually solve it.

2005 Chevrolet Avalanche

Just installed this on my 2005 Avalanche (since I'll be towing a larger travel trailer now), after seeing the how-to video on this site (relating to the same product). Overall the installation went very well, and I highly recommend this product. While my Avalanche had the factory-installed towing option, it did not provide an external transmission cooler and instead utilized a cooler built into the radiator tank (better than nothing, but an external cooler is best). If you're installing on a 2005-era Chevy 1/2 ton, do yourself a favor and order the D13002 Mounting Kit and the D13035 Radiator Adapter fitting; and while you're at it I recommend getting another 3' or so of 5/16" transmission cooler hose. The first two items make it a no-brainer to install the cooler, and while the cooler hose supplied with this cooler is decent, it's just not long enough to supply the hose lengths required to connect to the radiator and the existing line going back to the trans. Of course, I mounted my cooler in the center of the rad on the factory "A" frame (in front of the rad), if you somehow mount the cooler more to the passenger side then the supplied hose might be long enough. I ended up using two of the supplied self-tapping screws, but needed to obtain four bolt/washer/locknut combos to mount the brackets to the cooler's mounting holes. The cooler comes with four pads and plastic straps to mount it against the radiator, but no one I talked to likes those as they tend to break over time. Better off mounting it properly :-) Since I don't have a transmission temp gauge I can't tell exactly how much cooler it's operating, but a trans cooler like this is pretty much a requirement for any substantial trailer weight. 153766

Fun to install but if you follow the video it goes really smoothly. This was the number 1 recommended cooler for my 2012 Honda Odyssey Touring so I went ahead and got it. Before installing it I hooked my scanner to my van and drove 2 straight hours in the city and on the high way, transmission fluid temperatures would reach 195 at times. After installing it I tested the temperatures under normal driving and under towing. Under normal driving, after 2 hours the transmission fluid never got over 170. It took almost 3 hours before the transmission fluid reached 185. The van was already nice and warm when I decided to test towing so I'm not sure how long it took to get up to temperature but I can say after 45 minutes of driving through the Saura Town mountains (Hanging Rock, NC), the transmission temperature never went above 190. I would give 5 stars but the provided hose was not the correct ID and I could not get it to fit properly so I had to go buy more hose. 444073

The D13503 transmission cooler was a fairly straightforward DIY installation on a 2010 (3rd gen) Honda Odyssey. Watch a video or two on etrailer.com and you should be able to figure everything out. Two issues came up. First, it is not trivial to get the hose pushed securely onto the nipples of the cooler or the vehicle. Readers should thoroughly lube the inside of the hose and the outside of the nipple. (I suppose a tight fit is good, just be prepared to apply force and be patient!) Second -- and this is why the product only gets 4 stars from me -- the head of one of the plastic mounting rods broke off. No extras are supplied, so I figured out a zip-tie solution. It leaves me nervous about the strength of the remaining three, but the installation seems secure for now. Potential DIYers should also note that you are likely to break some of the body panel retainers (aka "clips") during disassembly of your vehicle's front end. (Not surprising on my 95,000 mile van; they were brittle.) Be prepared and locate a source for replacements ahead of time. Overall, this product seems well-designed, is offered at a great price from etrailer, and has the potential to lengthen the life of your transmission even when not towing. 348570

Installed the transmission cooler before our 15 hour trip to Florida from Kentucky. Previously had overheating problems with the transmission on long trips. The transmission never overheated during our latest trip with this new transmission cooler installed. Cooler came with everything available, with the exception of tools, to complete the installation. I will install another one if we upgrade to a later model Honda. 266795

Product delivered exactly when they said it would be. Installed on 2009 silverado with the 4.8L. Plastic clips are more than adequate to mount, making install that much easier. The grill would restrict airflow if I mounted to the supports. All my towing is done in the summer, so anything that will help my truck is worth it. Crew cabs are ridiculously expensive, trying to get mine to last as long as possible. 444958

2003 dodge caravan sport 3.3l. 110kmiles Where to start... Well it's okay. Fwiw, it's small and made of metal. I didn't know it but there was a trans cooler already installed in my vehicle, and it is aluminum much much better at dissipating heat. I read every review from here to there, watched all the videos. The common theme (sales pitch) is you can't cool your trans fluid enough. I will agree with that statement, but I also believe too much of a good thing is no good. When mounted the way recommended this unit sits directly in front of the air condenser/oem trans cooler/ radiator. It blocks some of the air that is passing through. **I did a before and after check using a infrared heat gun on the lines. It was a few degrees cooler under normal operating conditions, idle for a few minutes. I don't know what the difference is under heavy loads but imagine the difference may grow to as much as 10-15 degrees or so. Somebody in the laboratory (engineers) has this info, but they won't post it for obvious reasons. Not much of a difference at all, but if you are concerned about protecting your transmission, then this may help you to sleep a little better. I'm giving this three stars because while it will help me to sleep a little better it is fairly cheap in materials. The fasteners are plastic zip ties, (PLASTIC). If you've ever used zip ties you know they don't last long. I didn't have to use much hose and only used it on one side, the other end (existing line) was long enough so that worked out fine. I think if you have a newer vehicle this is the route to go as far as bolt on and go there's nothing i found easier than this. However, at over 100k miles, it was not fun at all. My fasteners were stubborn and I could not get behind the a/c condensor to secure the fasteners behind without disconnecting the a/c lines. I didn't have a problem with removing the a/c lines because after over 10 years the a/c was weak and needed to be serviced. This totally bit me in the rear. After assembly, I thought I could simply head over to the a/c shop for a recharge at a fair price. They got half way through and during the recharge mode their machine failed and it could not be completed. After doing extensive research (many many hours) into a/c service, repair and TMI (too much information) overload. My options were either to nickle and dime repair my a/c system or buy a complete a/c kit, spend an entire back breaking weekend installing it, then paying the shop to charge it, looking at upwards of 5 benjamins or more if I did it myself. I settled on an over the counter a/c recharge kit. It worked fine, but that took many hours of research to determine whether or not it was working correctly. In short, if you have a newer vehicle with less than 100k miles or so I'd recommend it only if you are occasionally towing upward of 75% of your vehicle tow capacity. If your towing weight is less, and you are not towing very often then your vehicle already has a cooler in it that should be more than sufficient. If you are towing beyond 75% of your vehicle capacity and doing it frequently, IMO I believe your best option is to get a tow vehicle with a higher rated tow capacity to begin with. For vehicles over 100K miles, it's your call. I did it, but I did it because over the course of 10+years my vehicle rarely carried much weight in it at all and it was always serviced regularly except -as mentioned - the a/c. I still think my transmission has a lot of life in it, and for what I paid on this D13503 in addition to suspension upgrades, I least I know that I did what I could as far as preventive maintenance. One final note, do not remove any more parts/grilles, nuts and bolts, wires, lines on your vehicle than absolutely necessary. Make it as simple on yourself as you can. Some of these videos have you cutting lines, adding compression fittings, ( I didn't need any) removing wiring harnesses, etc, etc,,. Look at the big picture. Every install is a little bit different. And if you decide to go with this transmission cooler it should drop right in and you can carry on with whatever else is more important, family, friends, life, etc.. Thank you very much for reading my review, and may you have a wonderful day. Olajoe 93170

ETrailer was extremely helpful in arranging an exchange on a trailer wiring harness that was ordered in error and processing the order for the Derale Transmission cooler kit. The installation went smoothly, although I did dock the rating one star because the inside diameter of the hose supplied is "extremely" tight fit to get over the barb on the Honda Odyssey trans cooler fitting on the radiator. One year after the purchase and installation of the Derale 8000 we have towed a total of 6,000 miles towing a Livin Lite 13QBB cabin trailer. No transmission issues and no leaks of any kind. I will be changing the transmission fluid in preparation for the upcoming summer travels and plan on doing that as an annual service. I highly recommend the Derale 8000 kit, although you may want to check the hose inside diameter against your OEM fittings and purchase appropriate hosing that is easier fit. 494211

This is a great transmission cooler, very sturdy. The only drawback is the suggested mounting method. The tiny little plastic string and clips that come with it just aren't up to the task. The cooler should be mounted with a bracket, period. The plastic clip method is used everywhere, not just here on etrailer, and it's not a good method. I would buy this cooler again and I would make sure that I mounted it properly. 317797

I dont have the cooler any more. I accidentally poked a hole in it when I was replacing the condenser. It worked great until I accidentally broke it!

I always enjoy my experience buying from etrailer. Troy my sales associate was very knowledgeable about the product and ensured I had all the parts i needed to complete my install. On most online sales transaction the sales associate is done when the order is placed, not so at etrailer, troy followed up with me to ensure i got all the products i bought. Installation was easy as etrailer has very good videos, makes me look like a pro, in my case I utilized the video on the chevy suburban to provide the basics for my silverado installation. The difference between the two is the silverado front grill snaps out and i did not have to drop the entire front cap. ALso had to fashion a mount for the cooler to support it to the A post. I just used two bolts and locknuts together with the two pieces of the bendable metal mounts (D13002). see photo. I took my trailer out this past weekend to test out the cooler. My transmission runs at least 20 degrees cooler while towing my 8000lb 5th wheel trailer. Max temps were at 160 deg. with air temps at 91 degrees, and high humidity in florida, typically this would be in the low 180’s rolling at 60 mph. transmission felt smoother while changing. I have a performance tune on my truck. Accelerating off the on ramps did make the transmission temp rise above 160 to around 165 then it fell back to around the 160 mark. It started raining heavily and the outside temps dropped to the 80’s and the transmission temp dropped to the 140’s. Normal driving around town with no hitched load in stop and go traffic with outside temps hovering around 95 with high humidity (feeling more like 103). here in tallahasse my transmission runs at around 140. I just checked my owners manual and my transmission oil and filter is past due for changing. i will get that done and see if anything changes. all in all this product works for me. Thanks etrailer!!! 539245

This cooler was easy to install. I did not use the insta-dapter fitting that comes with the cooler. I used a 5/16 barbed coupler instead. One thing I should note is: the instructions state, "warm the vehicle and locate the cooler line and that one will be the return". In my case the radiator made the return line hotter after warming the vehicle for several minutes. I had factory Honda cooler instructions available at install. So return line location was a no brainer. Derale instructions had me second guessing my connections after install was compete. It's installed on a 2002 Honda Odyssey with a newly installed transmission at 70K. I had to remove the headlamp assembly in order to tip the condenser coil far enough to get my hand behind it. 29861

2013 Toyota Tacoma

I put this on my 2013 Toyota Tacoma PreRunner as I wanted to have the added protection for my transmission, should I tow anything upwards of the max limit. The Tacoma with the tranny cooler and a class IV hitch can reach 6,500 pounds towing capacity, but I doubt I will test that limit. Had the Toyota mechanics install, as the truck was still under warranty and I did not want to take a chance in voiding it if it were put in wrong. I located it in the upper left front corner of the radiator, and using an infrared scanner, the fluid temp shows a noticeable drop from input to output. Bottom line is that was easy to install and does the job it was designed to do. 94413

I had put most of that info in my post. I installed on the drivers side, in front of the condenser and added an additional quart of fluid. Had the dealer do it, not me, so I have no idea if they used additional hose or not.

Decent kit overall. I have 2 issues... #1 Installation video and instructions glaze over the fact that in most vehicles there is only about 1/2 inch of room in between A.C. condensor (even after loosening bolts) and radiator making it extremely difficult to install using the included push rods. It took me forever and was a complete pain. #2 for my vehicle a 2006 Jeep grand cherokee, I apparently needed a special "GM" adapter even though my vehicle is not made by General Motors and nothing said I needed this special adapter until I took everything apart and found out whateber insta-adapt came with the kit was not going to work. I had to wait several days until I received the adapter to complete the install, again frusterating and not communicated to the buyer. 448106

I was looking for cooler to install on my 2007 toyota FJ cruiser because I was going to start pulling a 16ft airstream camper. I picked this cooler from etrailer because of it's quality and price. It was easy to install and it fit perfectly. My only negative comments about this product is that they didn't supply enough hose to attach both in and out lines. I had to go to a local auto parts store and buy and additional 3 feet of hose. The directions were pretty good, but I had a difficult time determining which transmission lines were in and out. This was on me not the product. Since the installation of this cooler I have pulled my camper across Florida and through the hills of Georgia without any transmission cooling problems. I would have given it 5-stars if they would have included 3-more feet of hose. I would buy it again 640805

I bought this so that I could tow my Polaris RZR with my 2008 Toyota Highlander. It has worked flawlessly and I haven’t had any problem after many hours of towing, including up several canyons and long trips. I always recommend people do their homework when making purchases like this, as it can greatly affect the performance of your car (as in potentially burn up your transmission). Installation was reasonably easy, though most of the challenges I had were inherent to my vehicle. I’d plan on the better part of a Saturday making this happen, if you haven’t done it before. Advice? Make sure you get the right size. Also make sure you install it in the correct in and out cooling lines! I haven’t had to think about this at all since installation, which is probably the highest praise I can offer. 615510

Box had a small ding, and box inside had been ripped open a little - But everything looked good. Video was great even though it was for a newer Dodge Grand Caravan. I had a few more things to remove, but felt good about everything until the install had Insta-dapt instead of the Snap in tube fitting that was in the video. The brass thread on the Insta-Dapt was smaller than the piece that came out. Everything comes to a screeching halt now till the new (Extra) part arrives. Wish it had been included. I have previously installed a trailer hitch that went smoothly. 603185
