Taken off a clutch fan on a 2002 jeep lib. - 2002 Jeep Liberty

Yes, clutch fans always turn. They just slow down with the RPM of the eng.

FAN SHOULD NOT BE LOOSE OR WOBBLY IF CLUTCH FAN BOLTS ARE TIGHT, MORE LIKELY FAN CLUTCH IS BAD NEED REPLACING.

Check clutch fan if you can spin it by hand freely with no resistance the clutch fan is bad.
if the clutch fan spins more than twice if you give it a good flip the clutch is bad.

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 !!!

Instead of cutting into your vehicle original harness, places like Best Buy sell the harness adapters for about $20 and you **** connect them to your radio and plug it into your vehicles harness. this way it doesn't mess with any grounds or security systems built into the car. It can also mess with the lighting if not careful.

if it low on oil the computor will shut the motor down or the sensor oil pressure is faulty

Look here.

your clutch on cooling fan could be faulty or your radiators cores is blocked and restricted.also grilled could be blocked restricting air flow.

try hitting clutch fan nut three times with bar and hammer and use adjustable wench to turn other wise you will need two tools can borrow from dealer of a parts shop one to wold water pump pully other to turn clutch nut.

If you have any questions feel free to ask. Let me know if you dont get diagrams(happens sometimes)

Reverse rotation water pump—2.5L and 4.0L engines

1. Before servicing the vehicle, refer to the precautions in the beginning of this manual.
2. Drain the cooling system.
3. Remove or disconnect the following: NOTESome 4.0L engines are equipped with a fan clutch that threads Directly on to the water pump shaft. This fan clutch is equipped with right-hand threads. NOTEDo not store the fan clutch assembly horizontally, silicone may leak into the bearing grease and cause contamination. NOTEOne of the water pump bolts is longer than the others. Note the location for reassembly.
   • Negative battery cable
   • Electric cooling fan connector
   • Accessory drive belt
   • Engine cooling fan and pulley
   • Water pump pulley
   • Power steering pump
   • Lower radiator hose from the water pump
   • Heater hose
   • Water pump and discard the gasket

To install:

1. Clean the mating surfaces of all gasket material.
2. Install or connect the following:
   • Water pump using a new gasket. Torque the bolts to 17 ft. lbs. (23 Nm).
   • Heater hose
   • Lower radiator hose
   • Water pump pulley. Torque the bolts to 20 ft. lbs. (27 Nm).
   • Power steering pump
   • Engine cooling fan and shroud. Torque the bolts to 31 inch lbs. (3 Nm).
   • Accessory drive belt
   • Electric cooling fan connector
   • Negative battery cable
3. Fill and bleed the cooling system.
4. Start the engine, check for leaks and repair if necessary.

3.7L Engine

1. Before servicing the vehicle, refer to the precautions in the beginning of this manual.
2. Drain the cooling system.
3. Remove or disconnect the following:
   • Negative battery cable
   • Fan and clutch assembly from the pump
   • Fan shroud and fan assembly. If you’re reusing the fan clutch, keep it upright to avoid silicone fluid loss!
   • Lower hose
   • Water pump (8 bolts)
4. Installation is the reverse of removal. Tighten the bolts, in sequence, to 40 ft. lbs. (54 Nm). Water pump tightening sequence—3.7L
