Video Transcript for Derale Snap-In Radiator Adapter Fitting for GM Review

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.

I purchased the Derale 9000 trans cooler to install on my 2017 GMC Savana 2500 to supplement the humorous excuse of a cooler that is installed by GMC. I carry a decent load most time, putting my van at around it's 8,600lb rating due to all of the tools I carry. I very rarely pull a trailer and empty out a good portion of my van when I do. On a hot day last week my trans temp crept to 206° and I decided it was time to do something to help. I installed this cooler yesterday and pulled my 6'x10' cargo trailer 15 miles both ways and the temp topped out at 184° which I think is great considering I had a full load out on my van and a light load in the trailer. The trans cooler is pretty straightforward to install. Mine took a little longer as I pulled my condenser loose to feed the fasteners from the back to the front, other wise I would have had to remove my fan shroud to access the straps to put the fastener buttons on. The most difficult potion was getting the fittings into the rubber hose, but pre-lube with a little ATF amd they will go in with some brute force. The cooler arrived in perfect condition, and appears to be a well built unit. All parts were present and after about an hour and a half or two it was ready to go. Just be sure to have addional AT fluid on hand to top the system off. All in all I'm happy with my purchase and look forward to seeing of it makes as much of a temperature difference as I'm hoping it will.

My first time to put one trans cooler in. Besides having to remove grill first, it went well and I love it! People give etrailer a try!



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:

Worked perfectly for my 07 Suburban Transmission Cooler Install.



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:

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:

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:

Great quality products!



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.

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



by:

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



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!

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:

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.

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:

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.

Purchased a quick fit tubing connector with my Tranny cooler from Etrailer a year ago and it has worked out great. Parts shipped out quick. Everything was of the highest quality. Very easy to install with the quick fit tubing connector. I will be sure to use Etrailer again.



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!

adapter was a perfect fit for 2004 Escalade ESV - allowed me to finish the installation. one year later no leaks!

  • Transmission Cooler Recommendation for 2008 GMC Yukon XL 5.3 Liter
    Hey Sam, I would recommend the Derale transmission cooler part # D13504 with the radiator adapter part # D13035 for your 2008 GMC Yukon XL with the 5.3 liter. This is a larger cooler that is the efficient plate fin design that we know works great on your Yukon and will make a noticeable improvement in your transmission fluid temps. Just be sure to install it AFTER your factory cooler to get the most cooling power.

  • Will the Derale 16-Pass Electra-Cool Remote Transmission Cooler Kit Work w/ a 2005 Chevy Silverado?
    The Derale 16-Pass Electra-Cool Remote Transmission Cooler Kit item # D15900 will definitely work for your 2005 Chevy Silverado 2500. You can use the Derale Snap-In Radiator Adapter Fitting for GM item # D13035 to make the installation easier.

  • Recommended Transmission Cooler for a 2014 Chevy Silverado 1500
    I recommend the biggest transmission cooler you can fit in front of your Silverado's radiator that has a plate-fin design. That is the Derale Series 8000 item # D13504 which is 11" wide x 12" tall x 7/8" deep. The 8000 series cooler item # D13504 uses plate-fin technology which is more advanced than tube-fin technology and will provide better cooler efficiency. To help with installation you can use the Derale Snap-In Radiator Adapter Fitting for GM item # D13035.

  • How To Find Return Line When Installing Derale Series 8000 Plate-Fin Transmission Cooler
    In regards to installing a transmission cooler like the Derale Series 8000 Plate-Fin Transmission Cooler part # D13503, you will need to identity the return line. In order to do this, take a few short laps around the block and then grab one of the two transmission hoses feeding the radiator. The cooler of the two hoses will be the return line. Please note, for GM applications you'll also most likely need the Derale Snap-In Radiator Adapter Fitting part # D13035.

For your 2010 Chevy Tahoe you would want to use the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class IV item # D13504.

  • Recommended Transmission Cooler 2007 GMC Yukon Denali
    I recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13504 for your 2007 GMC Yukon Denali. This plate cooler provides a large surface area to get the most cooling for your transmission fluid. You will need the Derale Snap-In Radiator Adapter Fitting # D13035 to fit your radiator when installing the cooler. I have linked an install video below that we have on a 2009 Yukon for you to reference.

  • Trailer Hitch and Transmission Cooler for a 2010 Buick Enclave
    You will want to be extra careful because just adding a transmission cooler and higher capacity trailer hitch will likely not get your Buick Enclave to the 4500 pound capacity. That much discrepancy in the tow package capacities suggests to me a difference in the drivetrain (motor, transmission) and/or the suspension as well as the rear axle. I can certainly help you out with adding a cooler and higher capacity hitch but you will want to check with a Buick dealer or GM technician to determine...

  • Can I Replace The Factory Transmission Cooler on a 2013 Chevrolet Silverado
    In regards to your 2013 Chevrolet Silverado, if you will be removing the auxiliary transmission cooler then I recommend using the Derale Series 9000 Plate-Fin Transmission Cooler Kit part # D13614 to replace it. This cooler measures 11" wide x 11-3/8" tall x 1-1/4" deep which you should have plenty of space for. In general we recommend that you install the supplemental transmission cooler in-line the factory transmission cooler (in radiator) and the auxiliary transmission cooler (behind...

  • Recommendation for a Transmission Cooler with Max Cooling Capacity for a 2007 Chevy Avalanche
    The Tube and Fin Class IV Transmission Cooler, item # D13105, is designed for towing with a gooseneck or fifth wheel trailer, up to 12,000 lbs. This transmission cooler will supply excellent cooling for your Avalanche and will not affect the performance of your vehicle when not towing. You cannot cool the transmission too much. The only consideration is that when it is very cold in the winter you should allow the transmission to come up to temperature before taking off or putting a load...

  • Transmission Cooler Recommendation for 2012 Chevy Silverado Towing 6,000 lb Boat
    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...

  • Recommended Transmission Cooler for 2019 Chevy Colorado Z71
    A stacked-plate cooler has the same design as a plate-fin, but it uses high-flow turbulators which makes it more efficient. Stacked-plate is typically for heavy-duty towing, and I don't think you need a combination cooler either. In your case, I believe a plate-fin will be more than enough to keep your temperature safe. You will want the largest cooler that fits in front of your radiator, which is the 11" wide x 8-3/4" tall x 7/8" deep Derale Series 8000 Plate-Fin Transmission Cooler Kit...

The Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13504 along with the hose kit # D13035 will work the best when lowering your transmission's operating temperature to help extend its life. This kit would be the most efficient cooler for your vehicle. This kit is specifically designed for Chevrolet Suburban's with a late-model, electronic...

  • Recommended Transmission Cooler for a 2008 GMC Yukon XL 4WD 4.8 Liter V8 294 Cubic Inch Engine
    The transmission cooler I recommend is the Derale # D13503 because it is Class-3 rated for more cooling. The overall dimensions are 11 inches wide, 8-3/4 inches tall and 7/8 inches deep. The kit # D13503 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. If you plan on towing anything weighing 5,000 pounds or more, I would go with the Class-4 transmission cooler # D13504. The overall dimensions...

This tube-fin cooler is a Class lV cooler and is a bit larger that the D13105, and would work well for you when placed in the best location on your truck.

This fitting will allow you to install the cooler without having to cut and flare the factory lines.

  • Should a Transmission Cooler Go After the Factory Cooler on a 2005 Chevy Silverado 2500HD

You may also need an additional fitting to avoid cutting and flaring lines. The correct fitting depends on the engine in your truck. If you have a 4.3 liter or 8.1 liter, use fitting # D13018. For any other engine size use # D13035. I have included some links on transmission coolers for you.
