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.

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. 787471

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 83914

Based on how this felt after installation, I was sure it was going to leak. I'm glad I was wrong. It works wonderfully. 242583

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. 851548

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! 848898

Purchased this with an Derale 8000 Series plate-fin transmission cooler. Fit perfectly into the factory radiator port for the transmission cooling line. End barb holds an 11/32" hose very well. lots of space for a worm clamp to be applied as well. 828869

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! 809672

Installed I about an hour in my ‘09 Tahoe. Been in for a week now and lowered the tranny temp an average of 15-20 degrees. I definitely needed the extra hose that was suggested in other reviews.

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. 682381

    In order to install an aftermarket transmission cooler on a 2015 Chevrolet Traverse you will only need to use one of the Derale Snap-In Radiator Adapter Fittings for GM part # D13035.

  • Is Transmission Cooler Adapter Needed to Install Derale Cooler in a 2004 Chevy Silverado
    You will want to also get the adapter part # D13035. The transmission cooler you are planning on installing, part # D13504 does come with universal fittings that can be used, but the # D13035 makes the install much easier as it snaps right into the radiator. I attached an install video that shows this cooler installed in a similar GM vehicle.

  • Where is the Transmission Return Line on a GMC Sonoma
    I really wish I knew exactly which transmission line on your GMC Sonoma was the return line but unfortunately, I do not have this information. However, if you drive the vehicle around the block and then grab each of the two transmission lines that lead in and out of the radiator that should give you a very good idea of which is which. The return line should be considerably cooler. Please note that in order to install a transmission cooler on a GMC Sonoma you may also need to use the...

    Some vehicles are required by the vehicle manufacturer to have a transmission cooler installed if they are to tow. Usually this information can be found in the owners manual. Regardless of whether or not a cooler is needed, it is a good idea to install one because it will keep the transmission fluid in the optimum operating temperature range, and prolong the life of the transmission.

  • What are the Measurements of the Derale Snap-In Radiator Adapter Fitting, # D13035
    I went out to the warehouse and pulled a Derale Snap-In Radiator Adapter Fitting, # D13035, to take some measurements for you. 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.

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

I have attached a short video review on this particular product that you can check out as well.

  • Does Install of Transmission Cooler on 2018 GMC Sierra 1500 Require Fitting Adapters
    According 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.

  • Which Transmission Line of 2004 Chevy Blazer to Install Transmission Cooler On
    On your 2004 Chevy Blazer the upper connection is from the trans, (hot). The lower connection goes back to the trans, (cooled). The lower line is the return line and the one you want to install a cooler on. For a transmission cooler the Derale part # D13503 would be a fantastic option. It measure 11" Wide x 8-3/4" tall x 7/8" deep and is a plate fin style cooler which is very efficient. The correct adapter fitting you'll want to use is the part # D13018.

  • Transmission Cooler and Oil Cooler Option for 2012 Chevy Avalanche
    Derale Transmission Coolers don't offer the bypass feature, but they do offer a bypass oil filter sandwich adapter for their oil coolers. The sandwich adapter has an internal thermostat that allows the oil to bypass the cooler when it reaches temperatures below 180 degrees. They do indeed offer highly efficient stacked-plate heat exchangers suitable for oil or transmission fluid cooling. For a stacked-plate transmission cooler, I'd recommend part # D13403. You'd also need the # D13035...

    Some vehicles require a special fitting when installing a supplemental transmission cooler but there is not one specified for the 2016 GMC Sierra 2500 with 6.0 liter motor. However, past models with the same motor did require fitting # D13035. It is possible that GM changed the radiator or something about the radiator after the 2015 model year, that I can't be sure of, but if they did not change anything then it does stand to reason that D13035 would be needed for a 2016 as well. But 2015...

  • 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.

    For your 2007 Chrysler 300C, the Derale Snap-In Radiator Adapter Fitting for GM # D13035 may fit but I can't confirm it. Most of the transmission coolers come with an insta-dapt radiator adapter like # D13004 that fits most vehicles and has both male and female threads to fit 5/16 inch transmissions lines. The GM specific adapter is a much nicer option for vehicles that fit, but your Chrysler is not on the list of confirmed fits.
