Why does your 2002 Dodge Durango overheat?

Answer 1

I don't know why Durangos overheat but here is a solution that has TOTALLY eliminated my overheating problems. I would add that I live in Dubai and we get months where the temperature is over 110F. My Durango would overheat quickly in traffic and cool down when travelling.

My Durango is fitted with a mechanical fan behind the radiators. There are three or four radiators each cooling Transmission Fluid, air-con gas, engine coolant etc. So I decided to fit two 10" diameter electric fans in front of the radiators blowing back towards the engine. The only problem is that you need thin fans as the space between the back of the closed hood and the first radiator is only about 70mm (2,75").

The workshop wired the fans to the air-con circuit so that if the aircon is on the fans are on and vice-versa. They needed a secondary relay for the fans.

This has totally solved my overheating problem as well as getting the air-con to work from start-up and keep working. I can leave the car to stand for ages and the temperature gauge stays below half all the time.

There seems to be several types of Durango overheating, but for my type this works.
