Derale 15502 High Performance Engine Oil Cooler Kit - Universal Fit for Cars & Trucks - Black Finish | Improves Engine Cooling & Extends Oil Life for Daily Driving & Towing

2016 Ram 1500 5.7 in AZ towing camper trailer or flat bed with rock crawler on it.Had high oil temps towing my trailer up certain grades up to around 250°. This helped lower those temps by 10-20° on average. I also did the louver trick at the same time. Gas mileage has not really changed as some have claimed.Easy install minus adding the hoses onto the barbs after I already installed the adapter. Would recommend installing hoses first fully before adding adapter on but check position and hose routing first. If you tow a lot grab one with the fan.
