How to Replace the Fan in Cars

by Contributing Writer; Updated June 12, 2017

The engine fan in the Jeep car helps the radiator to disperse heat energy from the engine and keep it within its operating temperature. The fan is mounted just behind the radiator. It includes a clutch assembly that alters the fan speed according to signals it receives from the engine thermostat. The clutch is driven by the water pump and automatically speeds up or slows down to maintain the appropriate amount of cooling.

Remove the Old Fan

Purchase a Chevy Cobalt radiator cooling fan to replace the old unit.

Raise your Chevy Cobalt and support it on jack stands or ramps. Make certain that the vehicle is secure and won't shift.
