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.

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

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! 302743

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. 296174

This is a customer service review not a product review. Leeza J. was very helpful in helping me get everything needed for adding a secondary transmission cooler to my Chevy truck. I ordered 3 different items and the one item was not in stock and I was promised that I would be notified when it arrived. I was notified that the item was in stock 2 days later and I received the package a few days after that. Very good service that impressed me. 377289

This product worked great for two reasons: It snapped perfectly into place after removal of the OEM hose connector (no leaks - by the way) and it eliminates the need to cut the end off of the metal tubing on your stock radiator hose. I would recommend attaching the cooling hose prior to installing the connector since the supplied hose is a very tight fit, I managed to fight with it better in the living room than under the truck. 61080

  • Tow Capacity of 4x4 2007 Chevy Silverado Classic with 5.3L and Transmission Cooler Recommendation

The max is usually either with the truck properly equipped or when using weight distribution. Your owners manual should be able to shed some light on this.

The Derale Transmission Cooler, # D13502, is one of the recommended coolers for the 2007 Chevy Silverado with the 5.3 liter engine.

  • Installing Transmission Cooler on 2009 Chevy Silverado Without Cutting Transmission Lines

The most efficient location to mount the cooler itself is directly behind the grille, in front of the radiator and A/C condenser.

A stacked plate cooler is going to be the most efficient. For a stacked plate that is very efficient and rated as a Class V I recommend # D13403. It measures 13 inches wide, 7-5/16 inches tall, and 2 inches deep. I also recommend fitting # D13035 so you do not have...

When towing up a high at low speeds using a low gear or towing mode, if available, would be the correct way to go about towing the trailer.

  • Sorry 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.

  • Can 11/32 Hose or Fittings be Used with 3/8 Inch Transmission Lines on a 2009 GMC Savanna 2500
  • We are talking about 3 hundredths of an inch and a short distance using the hose included with many of the transmission coolers that we carry. The slightly smaller size should not be a problem. The most popular cooler for the 2009 GMC Savanna is # D13503. I have included a link to a video showing an installation and a link to our help article on coolers for you. Using optional fitting # D13035 would allow installation without having to cut and flare lines.

  • When choosing a transmission cooler, it is always a good idea to go with the largest one that will fit in the available space in the engine compartment.

  • 2010 GMC Sierra 2500HD Transmission Cooler Recommendation
  • For your 2010 GMC pickup truck I would recommend that you get a Derale Transmission Cooler for the 2010 GMC Pickup, Sierra, part # D13105. The ideal transmission fluid temperature is from 160 to 200 degrees, 240 is way too hot and you should definitely upgrade your transmission cooler before you pull your trailer again.
