Q: What Checks Should Be Performed for Fan Clutch,Belt-Driven and Electric Fans?
A: For belt-driven fans, perform the following checks: Disconnect the negative battery cable and check for excessive bearing play by rocking the fan back and forth by hand. When the engine is cold, turn the fan blades by hand to ensure they turn freely. For electric fans on V6 engines, first, check the fuse and then unplug the electrical connector for the fan motor and apply battery voltage to test the fan. If the fan motors, fuse, and relay are functional but the fan is not working, check all wiring and connections to the fan motor and have the cooling fan system diagnosed by a qualified repair shop if no obvious issues are found. To remove the electric fan, drain the cooling system and remove the upper radiator hose and Coolant Reservoir. Installation is the reverse of removal, ensuring the fan assembly fasteners are tightened securely.
