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.

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: Aaron W.05/31/2024
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.

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.
by: Robert07/27/2020
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.

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

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.

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: 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.

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

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.

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.
by: Rhett09/18/2016
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.

view full answer... - Can a 2006 Buick Lucerne Tow an 800 Pound Trailer without a Transmission CoolerAccording to the owner's manual for the 2006 Buick Lucerne it has a gross trailer weight capacity of 1,000 pounds maximum. It does not say that a transmission cooler is required. However, a transmission cooler is always a good idea, especially when towing, to keep the fluid cooler so the transmission is less likely to get damaged or wear out any faster than normal. If you do decide to install a cooler the most popular option for models with the 4.6 liter V8 is # D13503. And we also recommend...

This will keep the fluid much cooler which will prolong the life of the transmission. Your fluid is getting too hot, I would strongly recommend a cooler. Full synthetic fluid won't help keep the temperatures down, but it might help prevent the fluid from breaking down. You will want to measure the area in front of your radiator to determine if this cooler...

Both types of coolers operate the same, but the plate-fin coolers uses smaller plates to allow more fluid to contact the aluminum surface inside the cooler. More surface contact results in greater heat dissipation. I have attached two FAQ articles on transmission coolers for you to check out.

- Recommended Derale Transmission Cooler for 2010 Silverado with 4.8L EngineThe highest-efficiency transmission cooler for your 4.8L 2010 Silverado is the Derale Class III Plate-Fin cooler # D13503 which you will install using hose fitting # D13035. This is the most popular trans cooler for your truck and if you like you can refer to the many customer reviews to see what hundreds of etrailer customers think of this cooler after installing it.

The most efficient spot to install a cooler to ensure it gets maximum airflow is directly behind the vehicle grille, in front of the radiator.

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.

At 2,500 pounds dry you should be within the tow capacity of the Venture. If your total trailer weight is close to the limit of the van, then I would suggest a suspension supplement. Since you will be towing a camper that will have pretty much the same load each time, I would suggest the Timbren Suspension Enhancement System as it will not need to be adjusted for varying loads.

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.

You'll just need to add the Snap-In Radiator Adapter Fitting # D13035. I have linked two videos to illustrate the cooler and demonstrate its installation.

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.

However, you can add a supplemental cooler to help give you much more cooling capacity that the small unit in the radiator is capable of, which is especially useful if you do a lot of towing. I recommend using something like the Derale 8000 Series # D13503, but you could use just about...
