Hey All. I have an '87 Renix with 4.0 & manual trans. All of my thread searches indicate that the temp sensor which triggers the electric cooling fan should be in the passenger side radiator tank. Mine has a temp sensor in the driver side lower radiator hose. This lower hose is in two parts with a metal tube with a bung in it to which this sensor is mounted. Do I have a transitional model being an '87 (first year of the mighty 4.0) with an alternate location for this sensor? Just wondering as I'm not certain that my electric fan works. As I only drive it in the winter and the remainder of the cooling system is in perfect order it could be that it's never reached a temp high enough to trigger the fan. I don't want to spend time testing the wrong sensor. Thanks in advance for your replys.

 

You can test the fan at tue plug with a couple pieces of wire.

 

sensor should be in the driver side rad tank near the bottom of the air box ,that other sensor most likely add on

 

If you have dealer installed air conditioning, the sensor will be in a metal tube in the middle of your lower radiator hose.

 

Thank you! Mine does indeed have AC and I now know that it was dealer installed. I appreciate the info. Thanks again.
