Derale 15660 Hyper-Cool Remote Engine Oil Cooler , Black

I installed this on my Ram 1500 and it made a significant improvement. On average my engine oil stays 20 degrees cooler even when towing heavy loads.

This thing is the bees knees. I was having overheating issues on my Dodge Ram while towing my RV. The cooler was easy to install and all of my overheating issues are gone.

The aluminum shroud is stressed too much where it is bent and is cracking. The universal adaptor is not so universal as it didn't fit my truck. Careful of the fittings, look inside them and knock out any shavings or they'll end up in your oil. The cooler itself is nice.
