2001-2004 Motorcraft F-150 SVT Lightning 5.4 Fan Clutch | YB 3041 by Motorcraft

Lightning Replacement Cooling Fan Clutch
This replacement 2001-2004 Lightning fan clutch can help get your cooling system back in order. When the engine is cool or even at normal operating temperature, the fan clutch partially disengages your Lightning's cooling fan, located at the front of the water pump and driven by the serpentine belt. This saves power, since your engine does not have to drive the cooling fan at full speed. When your Lightning's engine temperature rises above the fan clutch's engagement temperature, the fan becomes engaged, and draws more air through your Lightning's radiator, which lowers the coolant temperature to an acceptable level.

Lightning Fan Clutch Failure
When your Lightning fan clutch fails normally it will stop engaging and will allow the fan to spin freely, not pulling in the amount of air required to cool your Lightning's engine. This will cause your engine to overheat and for your air conditioning to stop cooling as well because the air conditioner's condenser is located in front of your Lightning's radiator. Though not as common another symptom of fan clutch failure is when the fan clutch is locked up or always 100% engaged. If this happens during the winter months the heater will blow lukewarm air instead of hot air.

Fitment Note
Will only fit models with 36mm fan nut.
