MY radiator fan has stop running which is causing my car to run hot. I was told by somebody that if the fan is burned out that the fan would be stiff, it would be hard to turn. My fan is easy to turn so do I need a new fan or could it be an electrical problem?And is this true about when a fan burns out? My car is a 1998 Cavalier 2.2 :165,000 mi

When the engine is running hot and the radiator fan should be on, check for 12 volts to the fan. If there is no voltage, there is a relay or sensor that has failed. If there is voltage, then the fan motor needs replacing.

Suggested Repair

With the engine hot and the radiator fan commanded on, check for 12 volts at the fan. No voltage indicates a failed relay or temperature sensor. If voltage is present, replace the fan motor.

Conversation Summary

The owner of a 1998 Cavalier 2.2 with 165,000 miles says the radiator fan stopped and the engine runs hot. They were told a burned-out fan would be stiff to turn, but theirs turns easily, and they ask whether the fan or an electrical fault is the cause. The expert says to check for 12 volts at the fan when it should be running: no voltage points to a failed relay or sensor, while voltage present means the fan motor needs replacement.
