## Description

Derale 13503 Series 8000 Plate and Fin Transmission Oil Cooler , Black

Review: Cooler than the other side of the pillow. - What can I say that hasn't already been said already. Heat is a killer of transmission, whether or not you tow. Stop and go traffic, short trips, excessive idling all add up to heat. The stock transmission coolers on most vehicles is laughably inefficient. I had purchased this as an add on to the transmission cooler already in the radiator of my 2002 Trailblazer, only to discover that the stock cooler was leaking. So instead of replacing the radiator (project for another day) I installed this instead. This, along with the Efan replacement, has done wonders in keeping my transmission cooler and happy. Mounted it in front of the radiator and condenser using the Hayden mounting kit. Also purchased additional hose, as the one supplied in the kit is never enough. Installation was a breeze. Cut the ends off the lines from the transmission, double flared them, attached the hoses, ran them to the front and attached the cooler. Mounted it up and topped off the fluid. It fits nicely in the space behind the grill and doesn't restrict the flow of air to the condenser and radiator. Worth the price.
Review: Instantly dropped 25+ degrees! - Installation: Installed on my 2008 Chevy Avalanche with almost no issue. I was able to install by removing the front grille inserts instead of the whole front bumper assembly which was a huge time/pain saver. I used the Derale 13002 metal strap mounting kit to mount to the metal bracket in front of the radiator. I did go ahead and purchase the Derale 13003 4' hose per previous review suggestions as the supplied hose is a couple of feet short of what was needed for my install. For a GM truck you'll need the Derale 13035 radiator adapter for GM to connect to the cooler to the radiator where you pull the factory cooler line from. Here's where my only problem arose. From the videos I watched on how to install this, I knew that tiny retainer clip that holds the radiator adapter in place was going to be the death of me. It was. As soon as I popped it off, it fell straight to the ground and, unfortunately, I don't have a garage or paved driveway to work in so into the gravels it went never to be seen again. Long story short...BE CAREFUL WHEN REMOVING/REPLACING THE RETAINER CLIP! Performance: I generally run a constant 185 degrees on most normal days and the other day I was in heavy interstate traffic and my gauge read 205. I'd been thinking about a cooler for a while and hitting 205 degrees sealed the deal for me. In the days since installing we've had some 90 degree weather and I've had some long and short driving distances and have observed a constant 165-167 degree operating temp since installing! In closing, I'm very pleased with the ease of installation and the many videos available online showing the installation of this product as well as the immediate temperature savings the cooler is providing. I highly recommend this item!

### ⭐⭐⭐⭐ A good, quality cooler. Just make sure you have at least 14" to 16" height clearance before purchasing.
*by V***Y on December 6, 2013*

I purchased this for my 2001 Jeep Grand Cherokee. Derale makes a good quality product and this 13503 is no exception. I was lead to the 13503 from another websites app guide which showed this as an option that would work. It dose fit '99-'04 WJ's, but, installation was not without it's complications. The 3/8 hose O.D. is too large to fit between the condenser and the frame, it's better to bend up some hard line to get around the radiator. My issue was the connections, the overall height caused interference between the hose connections and the frame which lead to a significant leak a few months after installation. Aside from that it performed perfectly well and I had no problems with the cooler itself. I ended up replacing it with the Derale 13611 9000 series cooler which was a much better fit for my Jeep. I will be installing this 13503 on my '82 K20 as there is ample room for the cooler with the hoses connected.
