Video Transcript for Derale Snap In Radiator Adapter Fitting Installation

We're going to show you how to install the Derale Factory GM Adapter, part number D1303l5, which helps us out, because it means we don't have to cut or alter anything on the vehicle as far as factory connections. Now, to slide this into our hose, we're going to wrap it up with a nice, soft cloth, just like that. Then maybe use a pair of pliers or something to hold it. You don't want to mar it, you don't want to scar it, because it makes the seal inside of there . Then we'll just kind of .. There will be good.

We'll have plenty of room here for our hose clamp. Slide that down on and tighten it up. Now we can take our adapter and slide it right into the back of the radiator, and re-secure it with the clip. That's going to complete today's installation of the Derale Factory GM Adapter, part number D13035.

Average Customer Rating:  4.8 out of 5 stars   (251 Customer Reviews)

Quickly and easily install your new transmission cooler without having to go through the hassle of cutting and flaring lines. Fittings are designed to work specifically with your vehicle's radiator.

by:

Based on how this felt after installation, I was sure it was going to leak. I'm glad I was wrong. It works wonderfully.



by:

Package arrived a day earlier than expected. Will be a week or two before installation. Products appear to be of great quality. Looking forward to installing the cooler.



by:

What I needed to install the Derale transmission cooler as a secondary cooler on my 2010 Suburban.



by:

Auxiliary radiator works great and was very easy to install after looking at etrailers video online.
I would have given it 5 Stars if the cheap piece of hose that came with the kit had not blown on the way home from work and sprayed all my trans fluid under the highway.



by:

Appreciate the recommendation to get this part for my install to be complete



by:

The transmission radiator , was a involved install, changed to a set of brackets, aluminum, to free float the radiator between the A/C dryer and Louvered shutters of the truck. Didn’t like connecting the two together for thinking heat sinking possibilities and become less effective. Was running at 139F, now 105F.
Your install video was very helpful to my planning and how I was going to do it. Install was on a 2020 GMC Canyon.



by:

Hello. I ordered your products for both my wife"s 2011 Chevy Suburban and my 2008 Chevy Silverado. My Silverado also needed the the trailer wiring which I also obtained from you. Thank you for outstanding customer service and great products. Delivery times were great as well. Please find atached pics of install in the Suburban.



by:

This made the installation so much easier. I hate cutting into any automotive lines (brake,coolant,transmission). Initially it doesn’t look like it will work but it does, no leaks.



by:

This adaptor was a must for the cooler installation as the adaptor included with the cooler kit did not fit my vehicle. This alloy adaptor was not listed for fit on my 2017 GMC Sierra. I contacted the manufacturer and they could not verify fit. I purchased the adaptor anyhow and compared gage measure to the original tube fitting on my vehicle and it was the exact fit. I would prefer the adapter be another 1/2"- 3/4" longer as I used two hose clamps at each hose connection on my installation to insure good seal.

The adaptor is working perfectly..No leaks!



by:

Works as expected, although the snap ring was hard to put back on. Maybe just that my fingers are too big to hold onto it and get it installed. Only thing better would be if it came with a second snap ring, I lost mine for about 20 min on the ground since it popped off while uninstalling the original pipe.



by:

I used this snap-in connector fitting in the Grand Caravan when I installed the Derale 8000 transmission oil cooler. Snap-in fitting worked great in the return side. Reasonably priced and quick shipping. Now I'll have to install a cooler in the daughter's van too! Thanks etrailer for the excellent support and products.



by:

Correctly worked from install, easy-to-use push-in fitting.



by:

Exactly what we were after, perfect!



by:

Snapped right in!

Still works fine. Hasnt leaked yet



by:

Product was exactly as described. Easily snapped into place where stock transmission line fit, and provided a simple way to add an addition transmission cooler with no cutting or awkward fittings

Part works as described. Im happy.

This is exactly what is needed to install a transmission cooler on a 2017 GMC Canyon diesel.

Absolutely no problems or leaks with this product.



by:

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!



by:

Worked out great for installing the extra trans cooler.

Anthony H.

No leaks still doing its job



by:

I received the cooler and Snap-In radiator adapter and thankfully it was sooner than expected. Everything was in order except that the cooler hose was 5/16" ID and the cooler and adapter are 3/8". Since the hose was not long enough (I needed 6ft) I was going to have to purchase hose anyway.
Everything works fine on my 2011 Chevy Traverse but unfortunately I neglected to take photos of the installation. However as a note for other Traverse Installers it is necessary to remove the front clip in order to gain access to the radiator. I made my own bracket to hold the cooler and mounted it in front of the AC condenser on the steel bumper which is accessible after the fascia (clip) is removed. I do not like the direct contact with the condenser. The bracket is bolted to the bumper as I drilled and tapped holes for the mounting points.
The clip is easy to remove after removing the inner fender guards. The factory manual suggests using a plastic wedge to unsnap the fascia below the headlamps. I used a plastic one that is used for installing glass/window seals.
It wasn't a quick install but not too difficult either. A significant part of the time spent involved the design,cutting and welding of the bracket.
Thanks,
Bob

Installed this in my 2008 Avalanche, utilizing the following kit:
D13504 - This cooler
D13002 - Mounts
D13003 - Extra hose
D13035 - GM adapter

Everything went well, took the longest time just figuring how I wanted it mounted in the front to make me happy, second to the time spent was of course removing the front fascia of the car. Once I got it in place the only extra things I needed were some P-clips for hose mounting, some split loom and zip ties(my necessity to prevent chafing ever). The GM adapter went in fine, was a bit leery of how 'loose' it felt even after being clipped in, it does move in and out about a 1/4" but this is normal and no leaks present, just make sure the clip retains the adapter. Pushing the new hose on the old hard line that went to the radiator is a bit of a bear, use lube on all your hose barbed ends to ensure easy insertion. Also when mounting the cooler, some screws were attached to the bracing of the car, pre-drilling those holes with a small bit helps tremendously, rather than risk trying to drive a self tapper in with force, slipping and putting a hole in your condenser.
After install, transmission is running about 30-40 degrees cooler in normal city driving, will test to see how it does with a tow load. Under towing I would get up to just shy of 220 degrees in the Florida heat, hoping to see it stay below 190 under load.



by:

I bought this because the transmission temp in my 2013 Avalanche was hitting 220 when towing a boat. Which seems high. After researching I found that transmissions in those models are ok up to a maximum of 275 degrees (which seems crazy but it is rated that high from chevy. There’s a website called Silverado.com that has a lot of info ). I installed this product and it worked really well. Easy install with the video if you have mechanical ability. Dropped temps by about 30 degrees. Still working great no problems. Only concern I have is that the transmission temp stays pretty low in the winter. It’s working well though. I would highly recommend this product. Good products, good service!

by:

We have been very happy with the performance of the transmission cooler. There was a significant drop in transmission temperature after replacing the stock cooler with your product when pulling our camper. Very easy to install on our Chevy pickup.



by:

Worked easily and perfectly for my 2008 Chevy TrailBlazer 4.2L with built-in transmission cooler, in order to connect to my additional Derale D13504 cooler using 11/32" hose. I was surprised that it didn't leak at all, as it snapped in so easily and could be spun, but it hasn't leaked in the year since I put it in.



by:

This is the exact part you will need to install transmission cooler on your GM vehicle. It connects the return hose to the factory cooler. I forgot to order it and then realized after watching some videos and reading reviews like this and luckily ordered it before the install. Great product. That was my first install of a trans cooler and I would have been stressed and baffled without this part. If you have a GM get it! Also, I saw it available elsewhere but this site is great and fast.

  • How to Install a Transmission Cooler on a 2010 Chevrolet Silverado 1500
    We always recommend that you install a transmission cooler inline with the factory cooler and not replace it. This is very simple to do and you will indeed use the factory transmission cooler lines for this. I have attached a sample install video if you need a better idea of what I am talking about. The transmission cooler I recommend for your 2010 Chevrolet Silverado 1500 is the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13504. This transmission cooler is 11" wide x...

  • Transmission Cooler Recommendation for 2005 GMC Yukon
    A stacked plate cooler like the part # D13402 will be more efficient than your current cooler but your best option is to install the cooler after your factory one so that you get the efficiency of both coolers to maximize the cooling effect. You'd also want the fitting part # D13035 to make the install easier.

  • 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 weight....

  • What is Meant by the Different Classes of Transmission Coolers
    Transmission and oil coolers are given class designations since we are in the towing business and those who tow are used to seeing class designations on hitches, ball mounts, etc. The idea is to give a general idea of the cooler's capacity, so if your vehicle has a class III hitch then a class III cooler should be fine. However, since coolers are NOT vehicle-specific you can use as large a cooler as you have space to mount it. There are various types of coolers and they can be either...

  • Recommended Transmission Cooler with Fan for 2012 Chevy Suburban
    I spoke with my contact at Derale and he said that your 2012 model Chevy Suburban 1500 uses 1/2 inch transmission lines so the Derale Hyper-Cool Transmission Cooler # D13960 won't be the best option. For your Suburban you will instead want the Derale Hyper-Cool # D15960 which is essentially the same cooler with fan but designed to work with the 1/2 inch lines. An adapter isn't needed as the compression fitting that comes included with this cooler should work perfectly. A transmission...

  • Transmission Cooler Recommendation for 2008 Chevy Silverado
    The best way to use a supplemental transmission cooler is to have the fluid go from the factory cooler then to the supplemental cooler as this will maximize cooling power. For a full size truck like yours I'd recommend a larger cooler like the Derale part # D13504 which measures 11" Wide x 12" tall x 7/8" deep. You'll also want the fitting adapter part # D13035 which will make installing the cooler much easier.

  • 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...

  • Installing Derale Series 8000 Transmission Cooler # D13503 On A 2016 Dodge Grand Caravan
    For your Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class III - Efficient # D13503, I recommend using the Derale Snap-In Radiator Adapter Fitting for GM # D13035 to make the installation easier. The kit comes with an insta-dapt radiator adapter that works with most applications, but this adapter is confirmed to fit and will work much better with an easier install.

  • Transmission/Oil Cooler Recommendation for 2012 GMC Yukon XL
    I'd recommend a combination transmission/oil cooler like the Derale # D15902. The cooler would mount just behind the grille in front of the radiator. The transmission circuit would tap into the return line from the radiator to the transmission, and the oil circuit would tap in via a sandwich adapter that installs between the oil filter and the filter landing on the engine. The kit includes the cooler, the hoses, the fittings and the sandwich adapter. Also recommended is the # D13035 fitting...

  • Is Derale Transmission Cooler # D13504 A Good Fit for 2013 Chevy Suburban
    The Derale # D13504 is a great option for your 2013 Chevy Suburban. We organize them by typical application but the bigger the cooler you can fit the better and this is a great size for your vehicle. You'll want the adapter part # D13035 as well too to make installing the cooler easier.

    Yes, you can also install the Derale Series 8000 Plate-Fin Transmission Cooler # D13503 on your 2018 Chevrolet Colorado with the 2.8L Duramax engine. This cooler is a great addition to most vehicles that are towing, especially in the hotter climates or are subjected to a lot of stress when towing(stop and go). Installation is made easier on your Colorado with a Derale Snap-In Radiator Adapter Fitting # D13035 that allow you to not have to cut your transmission lines. By keeping the transmission...

  • Recommended Transmission Cooler for 2007 Cadillac Escalade
    When towing a trailer, especially when there are hills or mountains, you will be wise to add a transmission cooler. For your 2007 Cadillac Escalade, I recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets # D13503. For this installation you will also want the Derale Snap-In Radiator Adapter Fitting for GM # D13035 if you have the snap in transmission line or the Derale Radiator Adapter Fittings for GM # D13018 if you have the threaded fittings on your Escalade....

  • Transmission Cooler Recommendation for a 2011 Chevy Silverado 1500 with 4.8 Liter Engine
    Some vehicles are required by the vehicle manufacturer to have a transmission cooler installed if they are to tow. Usually this information can be found in the owners manual. Regardless of whether or not a cooler is needed, it is a good idea to install one because it will keep the transmission fluid in the optimum operating temperature range, and prolong the life of the transmission. For your 2011 Chevy Silverado with a 4.8 liter, the most popular cooler is the Derale Plate-Fin Cooler,...

  • Should I Install a Transmission Cooler On a 2020 Chevy Traverse Without Tow Package
    In regards to towing, it's never a bad idea to add an additional transmission cooler. The factory tow package on most vehicles like a 2020 Chevrolet Traverse comes with a larger or additional transmission cooler so if you don't have the factory tow package and are still looking to tow a trailer then it would be a good idea to add one. I recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13503 along with the Derale Snap-In Radiator Adapter Fitting part # D13035. In...

  • Transmission Cooler Recommendation for a 2010 Chevy Suburban with 6 Speed Automatic
    The transmission you have in your 2010 Chevy Suburban is either the 6L80 or 6L90 since you said it is a 6 speed. Because of that the part # D14207 is not a fit since it is for 4L80E transmissions. You would need to go with a supplemental cooler that mounts in front of the radiator like our super popular part # D13504. You will also need the fitting part # D13035 to make the install easier. I attached an install video that shows this cooler being installed on a similar GM SUV as yours as well.

  • Routing Recommendation for Transmission Cooler # D13503 When Installing on a 2009 Chevy Silverado
    Yes, you will want to route the factory cooler in the way that you described. You would want to route the Derale cooler after the factory cooler. By that, I mean you would want to run the transmission coolant line from the transmission, to the factory cooler, then to the # D13503, and finally back to the transmission cooler. Routing the coolers in that order is crucial, if you were to run the cooler before the factory cooler you would effectively be cooling the fluid and then reheating...

  • Derale Transmission Cooler Fit for 2007 Chevrolet Silverado 5.3L
    Transmission and oil coolers are not vehicle-specific. A transmission cooler can be installed in a vehicle so long as you have space to mount it in an appropriate location where it will receive proper air flow. You are correct that we do not show the 5.3L option among the engines offered for your 2007 Silverado. I checked our performance tuner applications and indeed the 5.3L appears there so it is likely just an oversight. My contact at Derale confirmed they know of no reason cooler...

  • Transmission Cooler Recommendation for a 2012 Chevy Silverado 2500 HD
    Transmission coolers are not vehicle specific so you can install any one that will fit including # D13504. For the 6.0 liter engine you may need fitting # D13035. If you have a hard metal line and do not want to use the fitting, you could cut the metal line, flare it, and use hose clamps. The transmission cooler comes with hose, clamps, and mounting hardware. It also includes an Insta-dapt radiator adapter. This adapter is if you have a rubber line, not a metal line, so you can use the...

  • Correct Transmission Line Fittings to Install Transmission Cooler on 2009 Chevy Traverse
    According to Derale, the correct fitting to install the D13504 cooler in your 2009 Traverse would be part # D13035, if the return transmission line is attached to the radiator using an E-clip. You would need two of them. If the connection does not use an E-clip, you would need to use a compression fitting. The correct fitting will depend on the outside diameter of your transmission lines. For a 5/16 inch line use part # D13031, for a 3/8 inch line use # D13032 and for 1/2 inch line use...

    The Insta-dapt radiator adapter is included with the Derale Dyno-Cool Tube-Fin Transmission Cooler Kit item # D12904. It fits vehicles with 5/16" transmission lines and enters the radiator with a threaded connector. If you do not want to remove the fitting from your radiator you will want to use the Derale Snap-In Radiator Adapter Fitting for GM item # D13035. I recommend purchasing the second adapter.

    The Derale Stacked Plate Transmission Cooler part # D51906 is one of the most efficient transmission coolers out there so this would be an excellent option that would work great. With that said you'll want the version of this that comes with the install kit part # D13403. You will need the hose fitting adapter part # D13035 that you referenced as well. This allows you to easily plumb into the factory transmission cooler lines. I attached an install video that shows how the adapter is used...

This will work wonderfully in conjunction with the Derale Hyper-Cool Remote Transmission Cooler Kit that you have and there should be plenty of space to install this directly in place of the factory transmission cooler. The kit also comes with...

    A transmission cooler is a really great idea for your Dad's truck as the temperature range you mentioned is too hot to allow a transmission to survive very long. I'd recommend the Derale part # D13504 as it's a plate fin cooler which is one of the most efficient styles and is larger at 11" Wide x 12" tall x 7/8" deep so it's going to do a really great job reducing the temperatures to a much safer range. For an adapter to fit the truck's radiator to make the install of the cooler easy...
