Most Popular Class V for Ford Flex

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.
