Repeated Failures of New Fan Clutches

techtips_fanclutch.jpg

Multiple failures of new fan clutches on the same vehicle when the failure appears to be bearing, seal or shaft separation related should perform the following:

Closely inspect and replace the water pump if visible movement of the shaft in a vertical or horizontal direction is noted when checked by physically applying pressure to the fan blade in a front to back direction with the vehicle turned off and the battery disconnected.

The fan clutch and the water pump share a shaft and are related components. Always check and or replace your fan clutch when replacing the water pump.
