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.

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

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.

What I needed to install the Derale transmission cooler as a secondary cooler on my 2010 Suburban.
by: Larry S.02/28/2018
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.

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.

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

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: Stephen08/10/2023
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: Stephen07/08/2021
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.
by: Jon S.04/28/2020
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: John01/06/2023
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.

Absolutely no problems or leaks with this product.
by: Bill F.10/02/2016
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!

No leaks still doing its job
by: Bob G.06/09/2013
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 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: Gary08/06/2019
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: Robert06/10/2018
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: Wayne01/17/2022
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.

- Parts Recommendation to Tow a 7,500 lb Trailer with a 2000 Chevy C1500 TruckFirst let's start with a hitch, if you do not have a 10 inch deep drop bumper you would want the Curt Hitch part # C15325. If you do have a drop bumper you would want the Curt Hitch part # C15317. Now for wiring you will need to start with a 4-way like the Tow Ready Wiring Kit part # 118315. To convert this to a 7-way and install a brake controller you will need the Brake Controller Installation and 7-Way Install kit part # ETBC7. I attached an install video and installation instructions...
view full answer... - Selecting Transmission Cooler for 2002 Chevrolet Tahoe 5.3L V8 Towing 4000-lb TrailerMost transmission and oil coolers are not vehicle-specific (apart from the few pan types that are vehicle-specific) and so you can install as large a cooler as you have space for it. You cannot over cool transmission fluid so the largest most-efficient one that will fit is the way to go. The two linked articles will give you plenty of background on the types offered and installation guidance as well. I suggest the efficient Class IV Derale # D13504 that you referenced. Along with this...

The overall length is 2 inches. The larger flare is approximately 0.48 inches in diameter and the smaller flange is 0.43 inches in diameter. The diameter of the main body is 0.37 inches. And finally the diameter of the opening on either end is 0.27 inches. I produced a picture that shows the dimensions for you.

- Derale Combination Transmission and Engine Oil Cooler Installation on a 2007 Chevrolet SuburbanThe Combination Engine Oil and Transmission Cooler you purchased, # D15902, will work great on your 2007 Suburban, provided that there is 2 inches of clearance below the OEM oil filter for installation of the sandwich adapter and installation and removal of the filter and there is room for the oil cooler hose to be routed when the sandwich adapter is installed. Lets break the installation down to engine oil cooler and transmission oil cooler separately since the combo you purchased is...

- Radiator Fitting For 2005 Chevy Silverado 2500 With Derale RadiatorThank you for your purchase from etrailer of a Derale supplemental radiator like # D13502 for your 2005 Chevy Silverado 2500. There are adapter fittings for this, the Derale Snap-In Radiator Adapter Fitting for GM # D13035.
view full answer... - Recommended Transmission Cooler for 2008 Chevrolet TahoeFor a towing application adding a supplemental transmission cooler to your 2008 Chevy Tahoe 5.3L V8 is an excellent way to reduce thermal stress and help prolong the life of your transmission. The OEM cooler (built into the radiator) is meant for normal driving but by itself it will not be able to match the combined cooling performance you'll get from a secondary unit. I recommend the Class III-rated Derale Series 8000 cooler # D13503 and Radiator Adapter Fitting # D13035 which avoids...

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...
view full answer... - Troubleshooting Transmission Fluid And Engine Coolant Mixing On 2003 Cadillac CTSSorry to hear about the problems with your brother's 2003 Cadillac. The first thing you will want to do is have the transmission taken care of. I am not aware of a separate cooler for the transmission located under the intake manifold. Typically what is used is a line that runs from the transmission to the radiator. The radiator holds engine coolant and the transmission fluid line is run inside the radiator as well. The radiator cools both the engine coolant and the transmission fluid...

- Transmission Cooler Recommendation for a 2009 Chevy Silverado 2500 6.0 LiterThe most popular cooler for your 2009 Chevy Silverado 2500 6.0 liter and what I recommend is the Derale cooler # D13504. This is a larger cooler at 11 x 12 inches so it will offer a large area to cool the fluid. To avoid having to cut and flare lines I also recommend fitting # D13035.
view full answer... - Attaching Hose to Transmission Lines When Installing Transmission Cooler on 2005 Chevy SuburbanThe hose from the aftermarket cooler would simply slip over the flare on the end of the line that was removed from the radiator. There will be enough play in the line so that it can be moved back from the radiator. Make sure you slip the hose onto the line far enough so that the flare will prevent the hose from backing off the line once its secured with a hose clamp. I have linked you to some FAQ articles about transmission coolers that you might find helpful.

This fitting will allow you to install the cooler without having to cut and flare the factory lines. The flow of the transmission fluid will go from the transmission, to the factory cooler, out from there to the Derale cooler, and then from there back to the transmission. Adding a second cooler will be a tremendous help in keeping the transmission fluid temperature down closer...
view full answer... - Weight Capacity of Timbren Suspension Enhancement # TGMRAZT on 2006 Buick RendezvousThe 3000 lb rating for the Timbren Suspension Enhancement System refers to any load carried in the cargo area of the vehicle and applied to the rear axle, not the towing capacity. The only effect that towing would have on the Timbren system would be any tongue weight exerted on the vehicle by the trailer. The tongue weight (or downward force exerted on the trailer ball) would typically be 10 to 15 percent of the weight of the trailer plus the weight of anything loaded on it. If you are...
view full answer... - Transmission Cooler Recommended for 2003 GMC EnvoyTypically, the transmission lines make a loop through the radiator so if you're working your SUV hard while towing, you'd certainly benefit from a transmission cooler. Unless you live way up north where it gets seriously cold, it's difficult to over-cool a transmission. The best spot to mount a cooler is directly behind the grille in front of the radiator, so we typically recommend choosing the largest cooler that will fit into the available space. The Derale # D13504 measures 11 x 12...

I recommend using the Derale Series 8000 Plate-Fin Transmission Cooler # D13503 on your 2019 Chevrolet Traverse. As the transmission coolers we carry are a universal fit they do not always get listed for every vehicle. The Derale Snap-In Radiator Adapter Fitting # D13035 is specifically designed to fit GM radiators which have a snap ring holding the transmission line in place.

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 #...
