How do i remove my fan clutch on my 96 jeep grand cherokee?


Disconnect battery, remove bolts holding fan shroud, at the water pump where the fan shaft attaches. Unscrew the nut. It will remove the fan from water pump, lift out fan and shroud, 4 bolts holding clutch to fan.

I have a 2002 4x4 Grand Cherokee Laredo 6 cyl. automatic. Engine sounds like the engine is idling high but it is only 700 RPM.at idle. Does this sound like a harmonic balancer?


It may be the radiator fan making all that racket. Usually when the engine is cold, the thermal fan clutch allows more "slip" --- this allows the fan to turn slower than the water pump pulley (less load on the engine). When the fan clutch detects more engine heat, it reduces slippage of the fan clutch and this results in the fan turning "faster". It's actually turning at the same speed as the water pump pulley. The "roaring" noise is the result of the fan pulling in more air through the radiator.

If the noise is present at all times, whether or not the engine is hot or cold, then the fan clutch might be malfunctioning.


I hope this helps.


Have a nice day !!!
