What is the function of fan clutch?
Fan Clutches are ‘fluid’ coupling devices that provide air flow through the radiator by using the water pump shaft to power the fan blade. When the pump is cool or at normal operating temperature, the fan clutch will partially disengage.
How do I know if my fan pulley is bad?
To confirm the diagnosis, start with this simple test: Spin the fan as hard as you can on an engine that has not been started that day. If the fan rotates more than five times, you can bet the clutch is bad. You should feel some resistance and the fan may spin up to three times, depending on the ambient temperature.

Where do I find the serpentine belt routing diagram?
Find the serpentine belt routing diagram. Many cars come with a sticker in the engine bay that shows exactly how the serpentine belt is supposed to be routed through the various pulleys on the engine. If your vehicle does not have a sticker, you will need to find another way to remember how the belt should be run.
How is the tension set on a serpentine belt?
Depending on the application, your serpentine belt will either have tension placed on it using a movable bracket or an auto tensioner pulley. This pulley uses an internal spring to apply consistent pressure to the belt at all times. If your vehicle does not have a tensioner pulley, the alternator bracket is likely how tension is set on the belt.
