Bearing noise on the righthand side of motor sounds like the waterpump.How do I remove the serpentine belt and the viscous fan

The service and repair manual will help you to locate and fix the problem on your own easily with a diagram and you will get the manual from the given link http://toolsnyou.com/

Turn your A/C off, the compressor can make noise if bearings are dry or system is low on compressor oil.
Remove your serpentine belt. Turn pulleys by hand to check for roughness. Bearings in those pulleys routinely go bad.
You may get computer warnings with the following test, but with serpentine belt removed, run engine for 2 or 3 minutes. Do this on a warm engine after serpentine belt is removed. The warm oil will not mask the problem like cold thick oil can. Noise generated means problem is internal.
If this is a stick shift transmission sometimes the clutch bearing can make noise and is a sign that bearing is bad.

Hello: Remove the serpentine belt, see if the waterpump pulley wobbles/makes noise when you spin it. If thats not it then start the engine, belt still off see if noise is there also while engine is running see if vthe crankshaft pulley wobbles. Also check the A/C compressor pulley (engine off, belt off) spin it by hand and check for noise and wobble. If all the previous is ok then it could be the balance shaft front bearing and or the timing chain.

Would really need the model to be precise in diagnosing and giving the right instructions to repair this problem.I am assuming that by fan clutch that you have a viscous fan coupling bolted to your waterpump.Usually they dont get noisey,if they do,I would suggest that the fan would be either very loose and wobbly as you spin it while the engine is off,or it would be very stiff and rough to turn.Usually the fault is the waterpump bearing.It has the load of the fanbelt as well as the fan on it so it will wear out.If it is the fan,usually no need to replace the waterpump at this time,unless it is easy to get to at the same time,and for peace of mine if the mileage is getting high.This is assuming that it is the model that bolts to pump and isnt part of the pressed on hub on the pump shaft.This model is usually easier to replace as a whole unit-pump and viscous fan.I hope this helps you in decision making.

This is for the 3.9 v6 you did not specify motor size.
Hope this helps, it it does please leave feedback Thank You and Good Luck


The water pump can be removed and installed without discharging the air conditioning system (if equipped).

1. Disconnect battery negative cable.
2. Drain cooling system.
3. Do not waste reusable coolant. If solution is clean, drain coolant into a clean container for reuse.

WARNING: CONSTANT TENSION HOSE CLAMPS ARE USED ON MOST COOLING SYSTEM HOSES. WHEN REMOVING OR INSTALLING, USE ONLY TOOLS DESIGNED FOR SERVICING THIS TYPE OF CLAMP, SUCH AS SPECIAL CLAMP TOOL (NUMBER 6094). SNAP-ON CLAMP TOOL (NUMBER HPC-20) MAY BE USED FOR LARGER CLAMPS. ALWAYS WEAR SAFETY GLASSES WHEN SERVICING CONSTANT TENSION CLAMPS.

CAUTION: A number or letter is stamped into the tongue of constant tension clamps. If replacement is necessary, use only an original equipment clamp with matching number or letter.

1. Remove upper radiator hose clamp and hose at radiator.

Fan Blade And Viscous Fan Drive-3.9L/5.2L/5.9L Engines

1. The thermal viscous fan drive is attached (threaded) to the water pump hub shaft. Remove fan/viscous fan drive assembly from water pump by turning mounting nut counterclockwise as viewed from front. Threads on viscous fan drive are RIGHT HAND. A Snap-On 36 MM Fan Wrench (number SP346 from Snap-On Cummins Diesel Tool Set number 2017DSP) can be used. Place a bar or screwdriver between water pump pulley bolts to prevent pulley from rotating. Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.
2. If water pump is being replaced, do not unbolt fan blade assembly from thermal viscous fan drive.
3. Remove fan shroud attaching hardware (two bolts at bottom-two clips at top).
4. Remove fan shroud and fan blade/viscous fan drive assembly from vehicle as a complete unit.
5. After removing fan blade/viscous fan drive assembly, do not place thermal viscous fan drive in horizontal position. If stored horizontally, silicone fluid in viscous fan drive could drain into its bearing assembly and contaminate lubricant.
6. Do not remove water pump pulley bolts at this time.

Automatic Belt Tensioner Assembly-3.9L/5.2L/5.9L Engines

1. Remove accessory drive belt as follows: The drive belt is equipped with a spring loaded automatic tensioner. Relax tension from belt by rotating tensioner clockwise (as viewed from front). When all belt tension has been relaxed, remove accessory drive belt.
2. Remove four water pump pulley-to-water pump hub bolts and remove pulley from vehicle.
3. Remove lower radiator hose clamp and remove lower hose at water pump.
4. Remove heater hose clamp and heater hose from heater hose coolant return tube.

Coolant Return Tube-3.9L/5.2L/5.9L Engines-Typical

1. Loosen heater hose coolant return tube mounting bolt and remove tube from water pump. Discard the old tube O-ring.

Water Pump Bolts-3.9L/5.2L/5.9L Engines

1. Remove seven water pump mounting bolts.
2. Loosen clamp at water pump end of bypass hose. Slip bypass hose from water pump while removing pump from vehicle. Discard old gasket.

CAUTION: Do not pry water pump at timing chain case/cover. The machined surfaces may be damaged resulting in leaks.


Belt Routing-3.9L/5.2L/5.9L Engines

Serpentine belt tightener pulley bearing was bad, made a loud noise. I replaced the pulley (jobber part) and the noise level was reduced enough to notice the waterpump was also making a noise ... more revs = louder noise. I am now replacing the water pump. (approx 60k Miles too).

Congrats, I have one 1993 GC Limited and its a nice SUV...

5.2L Engines

1. Disconnect the negative battery cable.
2. The viscous fan drive and blade assembly is threaded into the water pump hub shaft. Remove the fan drive and blade assembly from the water pump by turning the mounting nut counterclockwise as viewed from the front while securing the water pump pulley. Do not remove or unbolt the fan drive and blade at this time.

Fig. : Fan blade and viscous drive (click for zoom)


The threads on the viscous fan drive are right hand threaded.

1. Remove the 2 fan shroud-to-upper crossmember nuts.
2. Remove the fan drive, blade and shroud as an assembly.

WARNING Do not place the viscous fan drive in a horizontal position. If stored horizontally, silicone fluid in the viscous fan drive could drain into its bearing assembly and the assembly would have to be replaced.
CAUTION Do not remove the water pump pulley-to-water pump bolts. The pulley is under spring tension.

1. Remove the 4 bolts securing the fan blade assembly to the viscous fan drive.
   

To install:

1. Install the fan blade on the viscous drive. Install the bolts and tighten them to 17 ft. lbs. (23 Nm).
2. Position the fan shroud, viscous fan and blade into the engine compartment as an assembly.
3. Position the fan shroud to the radiator. Insert the lower slots of the shroud into the crossmember. Install the upper attaching nuts.

Ensure the upper and lower portions of the fan shroud are firmly connected. All air must flow through the radiator.

1. Install the fan drive and blade assembly to the water pump shaft and tighten the nut.
   

Ensure there is at least 1 inch (25mm) between the tips of the fan blades and shroud.

1. Connect the negative battery cable.

WATER PUMP
The water pump is bolted directly to the engine timing chain case/cover.

A gasket is used as a seal between the water pump and timing chain case/cover.

If water pump is replaced because of bearing/shaft damage, or leaking shaft seal, the mechanical cooling fan assembly should also be inspected. Inspect for fatigue cracks, loose blades, or loose rivets that could have resulted from excessive vibration. Replace fan if any of these conditions are found. Also check condition of the thermal viscous fan drive. Refer to Viscous Fan Drive in this group.

The water pump can be removed without discharging the air conditioning system (if equipped)
