Most Popular Class III for 2017 Ford Flex

Installed this product on my 2013 Ram 5.7 Hemi. Install was simple and straight forward. I hoped there would be improvements in the operating temperature of my engine oil, which there was. Now towing my trailer is no worry about engine oil temp. This cooler works exactly as advertised, and the temp never go above 220. An unexpected result was better gas mileage by almost 2 additional miles per gallon. Also the truck runs much quieter than before and smoother. This noticed by my wife who rides with me always. So I would defiantly call this a win win install and purchase.

I purchased this kit 1 year ago for an 08 Toyota Highlander V6 Sport. The vehicle had a small (and I mean small) trans cooler already installed with the sport, but adding this additional cooler gives us the piece of mind an confidence that when either towing or evening just sitting in temps up to 116F at the drive through in SoCal during summer hours, my family will stay cool. The fans run less and the whole vehicle runs a bit cooler as well. I have verified this with 3rd party OBD readers, actively watching oil temps both at normal operating temps, hill climbs, towing, and when sitting in extreme heat. IT DOESNT BUDGE! I dont have enough good things to say about this cooler. If youve ever thought about it, you should do it. Very easy to install and it flat out works.

Installed the Derale engine oil cooler today. Excellent kit installed without any problems. Parts were very complete. I am pleased with the proiduct.

I bought this engine oil cooler so I could pull my 21 foot boat with my 2016 Ford Explorer. I am very pleased with how it works. It was easy to install even with having to remove the bumper cover so I could attach it to the front of the radiator. I would buy another one if I ever needed to. I would also buy from etrailer again, they have great prices and products.

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.

Happy to find a system with the adapter. Mounted to my 4runner very easily. Not much confidence in the plastic mounting method will make something else.
