Derale Plate-Fin Engine Oil Cooler Kit w/ Adjustable Sandwich Adapter (Multiple Threads) - Class V
just one problem the sandwich adapter will not fit on a 2008 Avalanche 4x4 the front drive shaft is in the way had to modify
Before I purchased this oil cooler, I was pulling my small boat loaded with camping gear over the willamette pass in oregon in the middle of summer. The temp outside was pushing 100 degrees and the road was a pretty steep grade uphill. My ram 1500 started singing with different bells and displayed engine temp was pushing 245 degrees. I started sweating bullets, hoping my engine wouldn’t blow up. After I got home I did some research and found this oil cooler. Hoping it would help and do the trick, I purchased it and hoped for the best. We went camping this year to the same location, and the entire way I was staring at all the temp gauges. My truck never got above 220 degrees. This thing works!

Derale Hyper-Cool Remote Engine Cooler Kit w/ Fan, -8 AN Inlets - Class V
Love my engine oil cooler. I was having overheating problems with my Dodge truck while towing on a hot day. I asked the guys at etrailer if I should add a bigger radiator, and engine oil cooler or another tranny cooler. They nailed it when they recommended a supplemental engine oil cooler. I now can town my fifth wheel RV trailer on the hottest days and in the mountains without overheating. I do still have to watch the temps and if they start to get over 260 f or so I downshift a gear or two to get greater fluid flows. The only reason I am not giving this 5 stars is that with the supplied hose clamps I was plagued with constant slow leaks. I finally bought a much higher end hose Clamp which did solve the problem.
I was surprised at the lack of feedback on these products, and the differences in opinions. I tow a fare amount, between 7000lbs and 9500lbs. My vehicle is a 2013 Dodge Ram 1500 with the 8 speed transmission. ( outside temperature 20-30 deg Celsius ). Before I installed this engine cooler my temperature ran around 115 deg Celsius on a flat pull and 130 - 135 deg Celsius on most hills. After a hill it took a long time to drop in temperature, most time it hardly dropped. Now I rarely see 115 deg Celsius on a hill, and recovers to 100 deg Celsius very quickly. So in short I'm very happy with this product. I would recommend it to anyone that Tows.
