drive belts (Fig. 1). One belt drives the generator, the
other drives the power steering pump and air condi-
tioning compressor (if equipped). The power steering/
air conditioning belt is tensioned by an automatically
controlled belt tensioner. The generator belt is man-
ually tensioned using an adjusting bolt and a locking
nut.

OPERATION

The accessory drive belts form the link between

the engine crankshaft and the engine driven accesso-
ries.

DIAGNOSIS AND TESTING - ACCESSORY DRIVE BELT DIAGNOSIS

CONDITION

POSSIBLE CAUSE

CORRECTION

BELT SLIPPAGE

1. Belt slipping because of
insufficient tension.

1. Re-tension generator belt.
Replace the power steering belt’s
automatic belt tensioner.

2. Belt excessively glazed or
hardened from heat and excessive
slippage.

2. Replace belt.

3. Incorrect belt.

3. Replace belt.

4. Driven component bearing
failure.

4. Replace faulty component.

5. Belt or pulley subjected to
substance (belt dressing, oil,
ethylene glycol) that has reduced
friction.

5. Replace belt and clean pulleys.

BELT NOISE (OBJECTIONABLE
SQUEAL, SQUEAK, OR RUMBLE)

1. Belt slippage.

1. Re-tension generator belt,
replace belt, or automatic belt
tensioner.

2. Foreign material imbedded in
belt.

2. Replace belt.

3. Non-uniform belt.

3. Replace belt.

4. Misaligned pulley(s).

4. Align accessories.

5. Non-uniform groove or eccentric
pulley.

5. Replace pulley(s).

6. Bearing noise.

6. Locate and repair.

BELT ROLLED OVER IN GROOVE
OR BELT JUMPS OFF

1. Broken cord in belt.

1. Replace belt.

2. Belt tension too loose, or too
tight.

2. Retension generator belt.
Replace the power steering belt’s
automatic belt tensioner.

3. Misaligned pulleys.

3. Align accessories.

4. Non-uniform grooves or eccentric
pulley.

4. Replace pulley(s).

5. Foreign object(s) in grooves.

5. Remove foreign objects in
groove.

REMOVAL

POWER STEERING PUMP AND AIR CONDITIONING
COMPRESSOR BELT

(1) Using a 17 mm wrench, rotate belt tensioner

clockwise (Fig. 2) until belt can be removed from
power steering pump pulley. Gently, release spring
tension on tensioner.

(2) Remove the drive belt (Fig. 3).

GENERATOR BELT

(1) Remove power steering pump/air conditioning

compressor drive belt.

(2) Loosen generator locking nut (Fig. 4).
(3) Raise vehicle on hoist.
(4) Remove accessory drive belt splash shield (Fig.

5).

(5) Loosen generator pivot bolt (Fig. 4).
(6) Loosen generator adjusting bolt until generator
