2015 Ford Transit Solutions for 2015 Ford Transit that Overheats When Towing in Warm Weather  


Have a 2015 Ford Transit with the 3.5L ecoboost. We use it to tow our 4000# 19foot travel trailer to Utah and California. When the ambient temps are 90, the engine temps get above normal and the engine frequently cuts power to reduce engine temperature. I cant fit a larger radiator in our van. Would a Derale engine oil cooler do anything to lower my coolant temps? What other options do I have to help our van run cooler? The transmission has a small auxiliary cooler that attaches to the side of the radiator. So a larger transmission cooler wouldnt help lower the radiator temps.


Expert Reply:

An oil cooler would be exactly what you would need to keep your 2015 Ford Transit from getting too hot when towing. I did some checking and the oil filter threads you would have on your van would be 22 mm x 1.5 mm which is a size that the Derale Cooler part # D15502 is compatible with.

You can also look into running distilled water in your radiator during the summer months this will also drastically reduce coolant temperatures. There's a product called Water Wetter that helps as well. You HAVE to go back to an anti-freeze mix if you ever will be in below freezing temperatures though.
