Are you getting that temperature measurement off the factory gauge or an aftermarket gauge? Have you measured actual engine temperature using a inferred thermometer at coolant temperature sensor body?

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

We changed the gauge. It is a VDO 0-250 temp. it only got to 200 this time. also we put a chip in it. Do you think this would cause it to get hot ?

Thx for the reply Larry

200F would be in normal range if it starts getting going around the 250F then I would worry.

IF it gets hot again feel both upper and lower rad hoses. If one is hot and one is cold you have flow issue or air in the system. I would also get a chemical test done to make sure it's not a headgasket leak. No a chip won't cause it to overheat.

Re: overheating ranger	Sign In

The flex fan is not the best cooling method .It flattens out in low speed high revs situations ,as in offroading , which gives you little airflow. IF class rules permit it get an electric unit mounted to radiator frame . You'll gain a few ponies to boot.
