Demot-Derale-Transmission-Coolers-D13503 Today we have Derale Series 8000 Plate Fin Transmission Cooler Kit, part number D13503. The kit comes with a transmission cooler, a new line, a hose clamp kit for attaching the new lines, and a mounting kit for the transmission cooler itself. It comes with these long post zips that work as a zip tie to secure this in front of your AC condenser. Transmission coolers are universal fit items. They are not vehicle specific; they are designed to fit anywhere there is space. In order to make sure it will fit your vehicle you want to find a spot where you want to mount a transmission cooler, and measure it to make sure there is adequate room.

Typically you want it in front of the AC condenser or at least in between the AC condenser and the Radiator itself. To give you an idea of some measurements weve got about 11 in width, 9 in height, and the transmission cooler itself is about 1 thick. So make sure that you measure on your vehicle that you will have enough space to mount the transmission cooler. This cooler is covered by 1 year warranty from the manufacturer, and that does it for Derale Series 8000 Plate Fin Transmission Cooler Kit, part number D13503. .

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


still working great!

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?

comment by: Don W - 10/25/2014


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.

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

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


Product has been working flawlessly, would purchase this again :-

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

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


kenWhat side of condenser did you mount your cooler? pas or driver side?Was there enough hose to reach for the in and out line?if you purchased more how much?How much extra fluid did you have to add after installation?any info will be very helpful. thanks

comment by: george s - 06/19/2014


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.

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


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.

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

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

Kit had everything needed for installing on a 2007 Saturn Outlook, except the connection to the radiator. Just need to buy part D13035. Then it makes install easier. No cutting and flaring lines. The dual fan on the engine side of the factory radiator will have to be removed to push the tie pieces through so the cap to make the tie tight can be added. 202466


I have a 2007 Outlook as well and we are looking to tow a 3000 lbs travel trailer across country. What will you be towing? was there any tricks to remove the front of the vehicle to access the radiator? where did you mount yours?

Installed quickly (once I figured out which line was the input and outlet from the radiator - tip: open line, then have someone start the engine, as soon as you see fluid squirting, stop engine. You now know which line is input/output). Towed boat with it just fine, towing trailer 5K this summer. All the websites say "be sure to install transmission fluid cooler if you are going to tow with your Odyssey." I'm glad this was so straight forward, and a good price (just like the wiring kit I ALSO just got from you). Thank you!!! Sterling 47022

Installed the transmission cooler into a 2005 Honda Pilot. The existing hose is not long enough so had to get a hose splice kit from local automotive supply - not a big deal, but would have been great to have this as part of the kit. The Pilot has two fans behind the radiator which is behind the A/C so I couldn't use the tie down straps, but the holes lined up well with the brace for the power steer cooler and I used stainless steel ties for the top. Overall the quality seems good and the product was delivered on time with no issues. 41261

Installation was done by my local Subaru dealer and at a reasonable cost. I did not want to do it myself since it was a new 2013 Outback and the front bumper had to be removed. They made a couple of brackets and mounted it with bolts instead of using the included plastic ties. We will be towing a Camplite model CL13QBB with a dry weight of 2100 lbs with our 4 cylinder CVT transmission and read the reviews on this cooler and went with it. The fit was perfect.

I bought this intending to install it myself. After getting it, I decided to have a mechanic friend install it and I am glad I did. It took him a couple of hours which means it would have taken me a lot longer... He had to remove the front bumper and lost of other covers, etc. to get at the radiator and condensor. Once all that was removed, he said it was pretty straight forward. I think it is going to work well and I would recommend this product and etrailer to others. 39555

Product is great. Instalation however was a bit more difficult on a 2008 jeep grand cherokee. I was not told when I purchased tne cooler that I would need to buy another adapter. Also I would suggest customers be aware that certain cars like my jeep cannot be serviced at home. When cutting the tranny line you lose some fluid.. I had to take my jeep to the dealership after instalation because the tranny is factory sealed and only the dealership can check or add fluid. 136793

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

The hardest task to installing was removing the Grille assembly from my vehicle (necessary). Had the cooler bolted in, radiator hardware installed and hose connected in about thirty minutes. All the necessary hardware was supplied with the kit but I opted to bolt the unit down with some drill screws I had. I strongly suggest that customers search for and watch the videos that etrailer has available. Great time saver. 98840

Installed this on my wife's 04 Honda pilot. I wanted to have piece of mind knowing I have extra protection on those sometimes "questionable" Honda transmissions. I would recommend one of these to anyone with a Honda pilot even if you don't plan to tow. The only reason I didn't rate it higher is because the provided hose is not long enough for a pilot. Other than that it is a great product!! 66362

I installed the Derale D13503 in series with my existing factory installed auxillary cooler for added protection on my Ford Explorer Sport Trac. With the Sport Trac tranny having the reputation for overheating failure, I took the cooling up a notch! I tow a 7X14 enclosed v-nosed trailer, and now I am protected! It was a very easy install, and the included hardware made it pain-free :-) 33187

Placed it on the 2013 Nissan Pathfinder SL, 4x4, with tow package. This car already has an external cooler tucked in front of the front wheel well driver's side. I wanted to plus it up with the efficient placement of this trans cooler by placing in front of the radiator and connected with the other existing cooler. Had to take off the bumper to make it happen, but it looks great. 79342

The transmission cooler worked but I had to modify it so it would fit. The quality of the cooler is questionable as well. Very thin material but I guess you get what you pay for. OEM cooler is $216 and this one was $50 so I kinda expected to have to modify or make it fit. Overall it works and I can drive my truck. So I'm happy but I wish it was closer to the manufacturer cooler 66225


We have a few different lines from Derale. The Series 8000 Plate-Fin and Dyno-Cool lines are lower cost items. They will still perform, but there are options if you are looking for something a little more robust. The series 9000 Plate-Fin Coolers and Stacked-Plate coolers would probably be more along the lines of what you are looking for.

Product arrived within a few days of ordering. All parts were there and after watching the instructional videos it was pretty straightforward on the install. The only problem I had was when I tied the new lines into the existing return lines using the 13028 Derale Dodge/Jeep Radiator Adapters. I had a lot of trouble getting those fittings into the old lines. 93842

Very easy to install providing you have an extra set of hands and are slightly mechanically inclined. The tube supplied was a little shorter than I would have liked it to be. An extra foot would have been ideal. I made it work, but I had to re-position the cooler when I realized I was going to be a few inches short. So far so good. 34354

Got cooler was delivered on time as promised. Pretty simple install. I felt like the hose should of been alittle longer. I had to purchase another section.

Product install was fairly easy. Mine was on a 2009 Silverado 1500 and after a few minutes I figured out that removing the airbox top half made installing the retaining e-clip on the etra radiator fitting so much easier. Temp dropped about 35 degrees under normal driving conditions. Definitely well worth the money and effort. 57164

The Derale transmission cooler arrived quickly and in perfect condition. Installation was easy, although the four feet of transmission fluid hose was not near long enough to install cooler on my 1986 F250. I went to six auto parts stores before finally finding some at NAPA. Order some with the cooler for ford trucks. 31335

Used in 2003 Trailblazer. Best if you buy the extra hose and mounting kit. Straight-forward install. C-clips are a bugger... Placement is the key.

Not too difficult to install. Slaved it into the system so I can use both the factory coolers and using these items as additional coolers. 51214


Hey Scott, Can you give me some advice on how you slaved it into the existing cooler? My guess would be that it gives you 2x the cooling?

comment by: Mark B - 11/21/2012


Chances are it would not be twice the cooling, but certainly more than either cooler by itself. Instead of by passing the OEM cooler, simply run the return line from the factory cooler to the new Derale cooler, and then out of the Derale back to the transmission. That is how the cooler was set up on the TrailBlazer video.

I read a review before I bought this one and it works great. Install time took me 4hr because it was my first time and I didn't really know how to take off my front bumper on a 2003 mdx. The kit came with everything I needed and everything fits. 74879

Installed on my 2009 Silverado 1500 w/ 4.8 which did not have the tow package or external trans cooler. Looks to be well built and was packaged nicely. Install was easy and so far it has reduced trans temp by 30 degrees on average. 168467

Do you have a question about this Transmission Cooler?

  • Can I tow a 30 ft Dutchmen Travel Trailer with a 2003 Ford Explorer
  • To determine if you can tow your 30 ft Dutchmen travel trailer with your 2003 Ford Explorer, you will want to find the towing capacity of your Explorer and compare that to the loaded and ready to tow weight of your trailer. I did some research on your Explorer and found that the Explorer will have different maximum tow ratings depending on how it is equipped. For 2WD models, if you have the 4.0L SOHC engine without a tow package, then the maximum towing capacity of your Explorer...

  • Transmission Cooler Recommendation for a 2007 Chevy Silverado 4x4 with Tow Package and 5.3 Liter
  • The ideal operating temperature for the transmission and fluid is between 160 and 200 degrees Fahrenheit. Transmission fluid cannot be overcooled, so adding an aftermarket cooler would be a good idea as factory coolers can be inadequate for towing applications. The Derale Transmission Cooler, # D13502, is one of the recommended coolers for the 2007 Chevy Silverado with the 5.3 liter engine. Since you are towing upwards of 9,000 pounds, I would recommend a higher capacity cooler like...

  • Recommended Weight Distribution for 2010 Nissan Pathfinder Towing 5800 lb Camper
  • According to my research, your vehicle is capable of towing 6000 lb Trailer Weight/ 600 lb Tongue weight if it is equipped with the V6 motor, or 7000 lb Trailer/ 700 lb tongue weight if equipped with the V8 motor. The use of a weight distribution system will not increase these towing capacities. For the purposes of choosing a weight distribution system, you will need to determine the fully loaded and ready to tow trailer and tongue weight. The weight of anything stored in the cargo area...

  • Parts Needed to Tow a Small Travel Trailer with a 1996 Toyota Tacoma
  • The towing capacity of your 1996 Toyota Tacoma will depend on if your truck has a V6 or a 4 cylinder and if it is a 4X4 or a 4X2. I have listed the towing capacities of the different options for the Toyota Tacoma below. 4X4 V6 - 8,300 lbs 4X4 4 Cyl. - 7,400 lbs 4X2 V6 - 8,300 lbs 4X2 4 Cyl. - 3,500 lbs You can verify the towing capacity of your truck by checking your owners manual or contacting a local Toyota dealer with your vehicle identification number. Toyota also places a...

  • Parts Needed to Tow a Casita Spirit Travel Trailer with a 2012 Kia Sorento SX with Tow Prep
  • Provided that you stay under the 3500/350 pound capacity of the 2012 Kia Sorento, it can handle a 16 foot standard/deluxe Spirit or the standard 17 foot model. The safe bet is to go with the 16 foot standard model but a deluxe should be fine. Your Kia will need to be properly equipped. Only models equipped a certain way can tow the 3,500 pounds. With a V6 and the tow prep package you should be at that 3500 pounds. Consult the owners manual to be sure. You can use Hidden Hitch trailer...

  • Is a Transmission Cooler Needed for Towing with a 2013 Nissan Altima 2.5 Liter And CVT Transmission
  • Installation of a Transmission cooler, like the Derale Series 8000 Plate-Fin Transmission Cooler # D13503, to cool the constant variable transmission fluid in the transmission on your 2013 Nissan Altima would be a good choice, especially if you are towing. A transmission cooler will help prolong the life of the transmission and will not cause any damage, as long as it is properly installed inline on the transmission return line. Testing has shown that for every 20 degrees of cooling...

  • Transmission Cooler Recommendation for a 2011 Chevy Silverado with 5.3 Liter Engine
  • The optimum temperature for transmission fluid is between 160 and 200 degrees Fahrenheit (70 to 93 degrees Celsius) so at 240 (116 Celsius) you were definitely above that range. When towing up a high at low speeds using a low gear or towing mode, if available, would be the correct way to go about towing the trailer. I would recommend adding a transmission cooler to your 2010 Chevy Silverado. I would use a class III or higher cooler rated for at least 6,000 pounds. You can use # D13503...

  • Transmission Cooler Recommendation for a 2013 Chevy Silverado 1500
  • All vehicles with an automatic transmission have a factory transmission cooler. Normally it is located inside the radiator but it can also be outside of the radiator. Trucks that have a tow package often have a larger cooler that is outside of the radiator. Regardless of where your factory cooler is located, you can still add a supplemental cooler because transmission fluid cannot be over cooled. You are correct about towing in warmer weather and in the mountains. It will increase the...

  • Why are Transmission Coolers Installed on the Fluid Return Line After the Radiator Mounted Cooler
  • The biggest reason that transmission cooler manufacturers and vehicle manufacturers want transmission coolers installed after the factory cooler rather than before it is because the transmission cooler in the radiator is surrounded by the coolant in the radiator. The transmission fluid leaving the radiator mounted cooler can be cooled further by the aftermarket transmission cooler. Installation before the OEM radiator mounted transmission fluid cooler would negate most or all of the...

  • Transmission Cooler Recommendation for a 2009 Chevy Silverado 1500 Crew Cab with 4.8 Liter Engine
  • The ideal operating temperature for transmission fluid is between 160 to 200 degrees. Your 2009 Chevy Silverado does have a factory transmission cooler, but factory coolers are often inadequate for towing. Since your fluid is reaching 250 degrees, you would benefit greatly from a transmission cooler. For your 2009 Chevy Silverado 1500 with the 4.8 liter engine, I recommend the Derale Transmission Cooler, # D13503. This is a class III cooler rated for up to 6,000 pounds gross trailer...

  • What is the Towing Capacity of a 2007 Dodge Grand Caravan with 3.8 Liter V6 Engine
  • According to the owners manual I viewed online for the 2007 Dodge Grand Caravan, if you have the 3.8 liter engine the gross trailer weight capacity at most is 1,800 pounds and 180 pounds tongue weight. This is with 2 people in the van and luggage. With 3 to 5 people and luggage the capacity goes down to 1,350 pounds and 135 pounds tongue weight. And with 6 to 7 people and luggage it goes down to 1,000 pounds gross trailer and 100 pounds tongue weight. I recommend verifying by checking your...

  • Recommendation For Transmission Cooler on 2008 Chevrolet Silverado 1500 LS With 4.8 Liter V8
  • Ideally you want to keep the temperature of the transmission fluid in the 160 to 200 degree range. You cannot cool transmission fluid too much. Transmission coolers are universal fit items so you will want to measure the space you have in front of your air conditioning condenser or your radiator to see what size cooler will fit your 2008 Chevrolet Silverado 1500. Installing an additional transmission cooler in-line with the current transmission cooler would help in cooling the transmission...

  • Can a 2009 Pontiac Vibe Safely Tow a 1,500 Pound Boat Trailer
  • Since you would be right at capacity I do recommend taking any measures feasible in lightening the load. That will make it that much easier on the vehicle. I do believe that properly equipped, the 2009 Pontiac Vibe will be fine towing the 1,500 pounds. Since you will not constantly be towing it up a steep ramp, and that aspect is only a small part of the journey, the Vibe should be just fine. For a trailer hitch, you can use # C12221 but it is for GT models. If you have a GT model then...

You should note that if your vehicle has lower capacities (sounds like it does), you would need to go by the lower figures as overall capacity. Right now for trailer wiring all we have is a universal install kit like part # 56146KIT. If Honda has a custom fit harness that might be a better option but this one will still work. For...

  • Are Transmission Engine Oil and Power Steering Coolers Needed For Towing with a 2007 Honda Pilot
  • Since the manufacturer recommends these aftermarket additions for your Pilot, we cannot suggest differently. The thing to remember is that if you do add these items and a warranty issue comes up, you have shown that you took the proper steps to ensure that your vehicle would perform properly so warranty service should not be a question. Another thing to consider is that heat is the enemy of your engine, transmission, and power steering. Using a cooler will dissipate more heat and prolong...

  • Replacement for OEM Transmission Cooler in 2006 Ford Crown Victoria Police Cruiser

You cannot cool transmission fluid too much, so the Class III cooler will provide better cooling when towing and will be good for the transmission around...

Whether or not any cooler will provide enough cooling depends on many factors specifically related to your vehicle and trailer setup.

  • Transmission Cooler Recommendations for a 1998 Chevrolet Silverado 4X4 5.7L
  • To determine what kind of transmission cooler you will need depends on how much weight you will be towing and where you will be towing. Also, you will want to check how much room you have in front of the radiator to be able to install the transmission cooler. If you will be towing a light load, less than 2000lbs, in flat driving conditions, your 1998 Chevrolet Silverado 4x4 5.7L will do fine with a class I rated cooler. If you will be towing more than a 2000lb load through some hills,...

  • Recommended Sway Control for a 2004 Chevy TrailBlazer Towing a 6,000 Pound Coachman Trailer
  • I can definitely help with the sway you are experiencing. First, one friction sway control unit probably is not going to be enough for your 6,000 pound trailer. A friction-type sway control can help mitigate trailer sway after it starts happening, but to stop sway in its tracks before it starts, you will need to break out a bigger gun, so to speak. I recommend going with Dual Cam High Performance Sway Control, # RP26002. The dual-cam system has a pro-active approach to sway control meaning...

You should be able to install the transmission cooler like you have described provided you have enough hose to reach. If you install it at the steel lines then you can use a hose fitting, # D13018 for the 4.3 liter or # D13035 for any of the larger motors, so you will...

The bottom line is that if you are towing something small a short distance or something large a long distance, a cooler will help to keep transmission fluid cooler thus prolonging the life of the transmission on your 2008 Dodge Grand Caravan.
