Question about Jeep Cherokee
Normal operating temp is between 200 and 210. If it gets hotter than that there is a problem. The system works as follows:
Temp sending unit sends signal to the computer which in turn completes the ground circuit to the relay which then turns on the fan. All connectors and wiring need to be clean and intact for it to operate properly.
To check initially you can put a piece of cardboard over the grille while it is idling and force it into a near overheat. If the fan comes on, it is working, if not, you need to trace the problem down.
