Most Popular With - 8 AN Inlets for GMC Yukon XL

Oil cooler works great, Only thing that I have an issue with is I can not use my stock oil filter with it. I have a 1992 Chevy K3500 with a 454 tonawanda 7.4 liter. In the instructions it is telling me to use a filter that is for a 350 or a 5.6 liter. But I was told by Derale that I should have no issues at all.

This is a good cooler however on a 4 wheel drive avalanche it's a challenge to get it installed in a position that will work with all of that equipment under there. I pinched the oring a little bit and it's leaking very slightly. On the next oil change I'll replace the oring, other than that this cooler works great.

I am extremely disappointed in this product. Installation has been a nightmare, even being someone that has automotive experience. From etrailer.com's recommendations to other customers I purchased this oil cooler for my 2010 Dodge Journey. DON'T! Unless you have access to some way to make a custom mounting bracket mounting is impossible. This CANNOT be mounted using the supplied method due to the stock cooling fan mounting shroud. After making my own mounting brackets from aluminum this cooler has done nothing but leak. It uses adapters, attached to adapters to make the connections to the tank, they leak. To attach the lines to the sandwich plate the instruct you to use teflon tape, or a similar sealant. With the temperatures and pressures involved keeping this from leaking took several attempts, not to mention oil sprayed all over the underside of my vehicle, including my brakes, and the front of my brand new trailer. Overall a very, very disappointing experience with this product.

Save your money. Two big problems. First, the sandwich plate adapter continues to work loose causeing an oil leak. I've removed the filter and retourqed to Derale specs a couple of times and it eash time after a couple of days it starts to leak again. Derale tech support was not at all helpful, they said, hmmmm, maybe tighen it a litte more, which I did, and it didn't help. Second issue is this cooler is very small, I installed it on a Ram 1500 5.7l and it made no noticable difference in the engine oil tempure when towing. I considered buying a larger cooler core and asked Derale tech support for some sizing guidance and their best response was put as big a one as will fit. Lot of science going on there. Couldn't give me any information regarding input and output temps vs flow, sizeing guidelines by displacement, nothing, no data of any kind seemed available. I'll make one more attempt to reseal, retighten, try a new o-ring etc. It doesn't work it's coming off and going in the trash. Overall the kit is sized for a very, very small application, maybe your riding lawn mower, that should be indicated. On a full size 1/2ton pickup this does next to nothing for your oil temp. Unfortunately tech support from Derale was no help whatsoever and showed not interest in helping trouble shoot or solve the problem. Very disappointing, I'd look else where.
