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.

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: 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.
by: Cory 04/25/2024
Appreciate the recommendation to get this part for my install to be complete
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.

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.

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

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

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.
by: Jerry S.07/14/2020
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: 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: 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.

- Oil/Transmission Cooler Installation in GMC Yukon XLIn the two Derale combination oil/transmission fluid cooler kits # D15902 and # D15903 the actual cooler core part is the same, measuring 17" wide x 12-1/2" tall x 3/4" deep, but the difference between the kits is that part # D15903 is a GM-specific kit while the other is a universal kit with more parts to allow it to work in more applications. These extra component parts are the reason for the higher cost. For your Yukon you will use # D15903 along with Snap-In Radiator Adapter # D13035. I...

It is the Derale Series 9000 Plate-Fin Transmission Cooler Kit w/ NPT Inlets item # D13613. This 11" Wide x 8-7/8" tall x 1-1/4" deep, radiator-style heat exchanger improves the performance and overall functioning of your GMC Sierra's transmission. Anything above 200 degrees starts to reduce the life expectancy of a transmission. You will need the Derale Snap-In Radiator Adapter Fitting for GM item # D13035 you were looking...
view full answer... - Is 247 Degrees Fahrenheit Too High For Transmission Fluid While Towing With a Chevy TraverseThe transmission fluid temperature you have of 247 degrees Fahrenheit while towing in your 2018 Chevy Traverse is on the high side. The transmission is not going to immediately blow up so to speak because of this but over time it can cause more wear to occur which then degrades the life of your transmission. I know you said that you already have a transmission cooler but it may not be larger or efficient enough for the trailer you are towing with your vehicle or the climate for that matter....

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...
view full answer... - Can a 2011 Chevy Silverado 1500 4.8L V8 2wd Tow a 3,500 lb Travel TrailerAssuming your towing capacity is 4,700 lbs, you can safely tow a 3,500 lb trailer. In fact, 2wd trucks typically have a higher towing capacity than 4wd trucks and long bed trucks, or trucks with longer wheel bases, hold up better to towing issues such as trailer sway and traction control. I checked the owners manual for your truck and it only discusses the towing capacity for the 6.0L engines, but according to Trailer Life Magazine's towing guides, your truck should have a 4,700 lb towing...
view full answer... - Transmission Cooler Recommendation for a 2005 Chevy Silverado 1500HDI would recommend you go with as big of a transmission cooler as you can fit in your 2005 Chevy 1500HD. You will need to measure the available space in front of the radiator to pick out the biggest one that will fit there. The part # D13614 would be an excellent choice as it is a very efficient cooler. It's dimensions are 11" Wide x 11-3/8" tall x 1-1/4" deep. Check out the review video I attached for more info. You will also need the fitting part # D13035.
view full answer... - How to Determine Which Line is the Return Line for Installing Supplemental Transmission CoolerIn order to tell which transmission fluid line is the return line leaving the factory cooler of a vehicle like your 2001 Chevy Silverado you want to start with your vehicle cold. Start it up and put it in drive and brake torque it (apply brakes and rev the engine), for about 10 seconds or so, put vehicle back in park, and turn engine off. Now quickly go out and feel both transmission lines. The cooler of the two is the return line and the one to use for installing the # D13035.

- Transmission/Oil Cooler Recommendation for 2012 GMC Yukon XLI'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...
view full answer... - Transmission Cooler Recommendation for a 2007 Chevy Suburban Z71 5.3 LiterFor getting your transmission fluid cooler the best solution would be a supplemental cooler like the part # D13503 that you referenced. 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...
view full answer... - Will Adding a Transmission and Oil Cooler Increase the Towing Capacity of a 2014 GMC Yukon SLTJust adding a transmission cooler and oil cooler will not increase the towing capacity of your 2014 GMC Yukon. The towing capacity of the vehicle is pretty much set in stone. But adding coolers will certainly be beneficial to you and help protect the transmission and motor for excessive heat. I recommend a combination cooler # D15902 so that you can have one unit that can be used for both fluids. I also recommend fitting # D13035 to avoid having to cut and flare transmission lines.

view full answer... - Transmission Cooler Recommendation for a 2013 Chevy Silverado 1500All vehicles with an automatic transmission have a factory transmission cooler. Normally it is located inside the radiator but it can also be outside of the radiator. Trucks that have a tow package often have a larger cooler that is outside of the radiator. Regardless of where your factory cooler is located, you can still add a supplemental cooler because transmission fluid cannot be over cooled. You are correct about towing in warmer weather and in the mountains. It will increase the...

Since it looks like you will be replacing your OEM cooler with this product you will need to remove the current fittings on your lines and then connect the new cooler over the flares and secure the included hose with the included clamps. We also have extra hose # D13003, universal mounting brackets # D13002, and a snap-in adapter fitting # D13035 that...

If your Tahoe has the 4.8L V8 I recommend the Derale Series 9000 Plate-Fin Transmission Cooler Kit w/ NPT Inlets - Class V - Extra Efficient # D13614, or if you have the 5.3L V8 I recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class IV - Efficient # D13504 instead.

Because we are in the towing industry, our customers are used to seeing Class ratings on their trailer hitches, so this is an easy way to alert the customer as to which cooler is the most efficient for their towing needs. Therefore we use the Class rating to let customers know that if they have a Class II...
view full answer... - Does Install of Transmission Cooler on 2018 GMC Sierra 1500 Require Fitting AdaptersAccording to Derale you would not use the # D13035 when installing a transmission cooler like the # D13504 on your 2018 GMC Sierra 1500 with a 5.3 liter engine. Instead the rubber lines of this kit attach directly without the use of an adapter.

For your Pilot I recommend using part # D13503 which is 11" wide x 8-3/4" tall x 7/8" deep and for your Avalanche I recommend using part # D13504 which is slightly larger at 11" wide x 12" tall x 7/8" deep. Either of these options will work well for you and provide your vehicle with adequate transmission fluid cooling. However, in order to install a transmission...

Since your vehicle will be virtually identical you'll need the adapter as well. I attached the install video below as well which you can use as a guide.

You shouldn't have any problem towing that weight in the mountains. It will give your truck a workout, but nothing it can't handle under wise driving conditions. You will want to make sure your trailer brakes, your brake controller, and wiring are all working properly prior to the trip as they will also be strongly utilized in the mountains.

view full answer... - How to Upgrade a 2006 Hummer H2 For TowingI do have some options for you but the radiator cooling fans are not typically the weak point in a towing setup. The factory clutch fan and or electric fans (if equipped) will be sufficient for most so long as you are towing within capacity. If you are having issues with the engine overheating then you most likely have other issues going on (i.e. stuck thermostat). With that being said, if you just want to upgrade to an electric fan setup then they don't really offer any exact fits for...

If you haven't already picked out a transmission cooler, the Derale Series 8000 Plate-Fin Transmission Cooler part # D13502 is what I recommend because it will be the perfect size for the Traverse.

The largest one we have is the part # D54006 which measures 13" Wide x 13-11/16" tall x 2" deep. For a bracket kit you would need the part # D50020, for AN fitting adapters you'd need two of the # D98200. For the fitting for your truck you would want the part # D13035. For a 5 foot section of hose we have the part # D13016.

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...
