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.



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:

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:

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.

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



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!



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:

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:

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:

Exactly what we were after, perfect!



by:

Snapped right in!

Still works fine. Hasnt leaked yet



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.



by:

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



by:

Fit perfectly! I have a 2014 silverado 1500 ltz with a tow package. The location of the trans cooler line is different than any DIY video you have but I found it and everything I recieved from Etrailer went together seamlessly.

E-trailer is my one stop shop for everything travel trailer.

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:

Fits correctly.



by:

Worked good easy hook up



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!



by:

Used this with my new transmission cooler install. Works great to install into radiator of my 2009 Suburban.



by:

Was adding an aux transmission cooler to my 2006 grand prix gxp. Adapter went right in with no problem.



by:

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:

Purchased this to use on my transmission cooler installation. Easy to install, easily adapts from GM radiator to rubber hose supplied with cooler.



by:

This product fits as it is supposed to. It is difficult to slide the hoses over the end but as other reviewers have mentioned this is actually probably a good thing to help form a tight seal. Also removal of the retaining C-clip from the existing connection is difficult under tight conditions and it is easy to lose that clip. The intent is for the clip to be re-used but that isn't exactly realistic in all situations, so I believe that a new clip should be provided with this product. That would have saved me a trip to the auto parts store during the install!

    In 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.

    The original transmission cooler line is held in by an E clip.

The transmission line will then come out of the radiator housing. You will then install the Derale Snap-In Radiator Adapter, item # D13035, using the E clip to hold the fitting in place. If this fitting leaks, an O-Ring in the radiator at this...

  • Determining Which Transmission Line is Return Line of 1993 GMC 1500
    While I wasn't able to get you the exact answer I can help you easily identify which transmission line is which on your truck. 1. Start engine while engine is cold 2. Place transmission shift lever in drive for no more than 10 seconds. 3. Stop engine and remove keys 4. Identify the oil return line by feeling both oil lines. The coolest line is the oil return line and the one to install the transmission cooler on.

  • Fitting Needed to Install Transmission Cooler on 2003 Chevy Silverado Without Cutting Lines
    The Derale # D13035 you'd looked at is the fitting you'll need to install a transmission cooler like # D12903 on your 2003 Chevy Silverado 1500. The # D13035 will allow you to install a transmission cooler without cutting the existing transmission lines, as you can see in the video I've linked for you. The video shows a transmission cooler being installed on a 2003 Chevy Avalanche, but the procedure would be identical for your Silverado.

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.

    The Derale Snap-In Radiator Adapter Fitting # D13035 that you referenced is not available in a 90 degree angle.

  • Attaching Hose to Transmission Lines When Installing Transmission Cooler on 2005 Chevy Suburban
    The 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.

  • Transmission Cooler for 2015 Chevrolet Suburban
    The largest transmission cooler you can fit in front of your AC condenser will give you the most cooling efficiency so I suggest Derale Cooler kit # D12903 along with Hose Fitting kit # D13035 for the 5.3L V8 engine. This cooler measures 15-1/4 wide x 7-1/2 tall x 3/4-inch deep; you will want to check the space in front of your condenser to ensure there is enough room to mount the Derale. The inlets/outlets can point in any direction. You will want to ensure that you can access the transmission...
