Fan belt fell off while driving, and the whole fan assembly is very loose causing the fan belt to shred. I have had some suggestions that it may be the fan motor but I am not sure.

The pulley that the fan is connected to and which the belt goes around is loose and making noise. Is it a bearing?


If the pulley is loose and the bolts are tight, chances are the water pump bearing has failed.

My fan is not moving when i start my engine. It's the fan near the radiator?


Is the belt that goes to the fan pulley assembly loose or missing? Tighten or supply a belt.

If a belt is present and tight, is the pulley rotating with the belt or stationary? If stationary, then the fan pulley assembly bearing is defective.

Need diagram for serpentine belt


14ae203.jpg

Fig. 1: Exploded view of the belt drive fan assembly-1992 vehicle shown

To install:
1. Position the fan on the drive clutch. Install the bolt and washer assemblies, then tighten to 12-17 ft. lbs. (16-24 Nm).

2. Position the fan drive clutch, fan assembly and fan shroud, then bolt the fan and clutch assembly to the water pump hub. Install and tighten the clutch retaining bolt and water pump assemblies evenly and alternately to 15-22 ft. lbs. (20-30 Nm) for the 3.8L engine or to 36-47 ft. lbs. (48-65 Nm) for the 5.0L engine.

3. Install the fan belt. Align the fan shroud and adjust for equal fan-to-shroud radiator clearance but maintaining a minimum of 0.38 inch clearance to the fan tip on 5.0L engines.

4. Install and tighten the shroud retaining screws. On 5.0L engines, snap the air deflector assembly to the sub-frame cross brace.

Smoke, smoke, smoke and alternator/fan belt shredded


If 1994 Suzuki equip with air condition then please check the A/C compressor clutch.

The compress clutch can lock up on a defect ai/c pump and cause the belt to smoke.

Please check for a fail a/c pump first and get back to me.

An fair A/C pump can be bypass via an a/c pump bypass pulley (as picture below)

You've covered all the reasons why fan belts shred. I would suggest looking closer, and making sure the bearings are good in all belt driven devices.

Changing the water pump on 2000 Jeep Grand Cherokee V6


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)

REMOVAL
Disconnect negative battery cable from battery.
Drain cooling system. Refer to Draining Cooling System in this group.
Do not waste reusable coolant. If solution is clean, drain coolant into a clean container for reuse.

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. Using special tool spanner wrench 6958 with adapter pins 8346 and a suitable fan wrench loosen the fan drive Viscous Fan and Fan Drive Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.
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.

If water pump is being replaced, do not unbolt fan blade assembly from thermal viscous fan drive.
Remove two fan shroud-to-radiator nuts Fan Shroud Mounting Hardware Do not attempt to remove fan shroud at this time.
Remove fan shroud and fan blade/viscous fan drive assembly from vehicle as a complete unit.
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.
Remove accessory drive belt as follows: The drive belt is equipped with a spring loaded automatic belt tensioner. Relax tension from belt by rotating tensioner clockwise (as viewed from front) Automatic Belt Tensioner - When all belt tension has been relaxed, remove accessory drive belt.
Remove lower radiator hose clamp and remove lower hose at water pump.
Remove seven water pump mounting bolts and one stud bolt
CAUTION: Do not pry water pump at timing chain case/cover. The machined surfaces may be damaged resulting in leaks.

Remove water pump and gasket. Discard gasket.
INSTALLATION
Clean gasket mating surfaces.
Using a new gasket, position water pump and install mounting bolts as shown. Water Pump Installation - Tighten water pump mounting bolts to 54 N·m (40 ft. lbs.) torque.
Spin water pump to be sure that pump impeller does not rub against timing chain case/cover.
Connect radiator lower hose to water pump.
Relax tension from belt tensioner Automatic Belt Tensioner - Install drive belt
CAUTION: When installing the serpentine accessory drive belt, belt must be routed correctly. If not, engine may overheat due to water pump rotating in wrong direction. Refer to Belt Routing for correct belt routing. Or, refer to the Belt Routing Label located in the engine compartment. The correct belt with correct length must be used.

Position fan shroud and fan blade/viscous fan drive assembly to vehicle as a complete unit.
Be sure the upper and lower portions of the fan shroud are firmly connected. All air must flow through the radiator.
Install two fan shroud-to-radiator nuts Fan Shroud Mounting Hardware
Be sure of at least 25 mm (1.0 inches) between tips of fan blades and fan shroud.
Install fan blade/viscous fan drive assembly to water pump shaft.
Fill cooling system. Refer to Refilling the Cooling System in this group.
Connect negative battery cable.
Start and warm the engine. Check for leaks
