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.

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.The order arrived on time and complete. The items fit, keeping in mind this is a universal cooler. I made lower brackets which allowed the unit to bolt on.
Very handy for unique installations fo transmission coolers
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.
Based on how this felt after installation, I was sure it was going to leak. I'm glad I was wrong. It works wonderfully.
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.
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.
I didn't end up having to use it, didn't need it. Shipping was quick, everything else I ordered worked perfectly.
It works and is convenient to have
Worked great. I used some small angle iron.. The holes
are the spacing as the cooler.. Used 2 self tapping screws
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.
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.
Snapped right in!
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
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!
fast shipping, great products
Exact part that was needed
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.
adapter was a perfect fit for 2004 Escalade ESV - allowed me to finish the installation. one year later no leaks!
JJ - 10/08/2020I used this to install external cooler on 2008 Chevy Silverado LT with 5.3. I have clip style fittings for transmission lines into radiator and this adapter was needed. It worked. No leaks one year later. Very happy.
Worked out great for installing the extra trans cooler.
Anthony L - 08/11/2020Couldn't install the radiator cooler without this part. It was a perfect fit and just what I needed. Over one year and 20k miles later there are no leaks or any other issues with this adapter.
Just what I need to complete the install on my 2009 Chevy Silverado.
I never used it. I eliminated the rad altogether ran the lines right to the trans cooler your cooler is working great. I tow a car and the temp never hits 170 great product. Thanks
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
