SOHC
DESCRIPTION
The accessory drive consists of one Poly-V type
drive belt that drives the generator, power steering/
water pump, and air conditioning compressor (if
equipped). The belt tension is controlled by an auto-
matic belt tensioner. If equipped with air condition-
ing, the accessory drive also has an idler pulley (Fig.
1) or (Fig. 2).

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. Refer to BELT SLIPPAGE above.
2. Foreign material imbedded in
belt.
2. Replace belt.
3. Non-uniform belt.
3. Replace belt.
4. Non-uniform groove or
eccentric/bent pulley.

ACCESSORY DRIVE BELT
REMOVAL
(1) Disconnect negative battery cable.
(2) Insert a 1/2” drive breaker bar into the square
opening of the accessory drive belt tensioner.
(3) Rotate accessory drive belt tensioner counter-
clockwise until accessory drive belt can be removed
from pulleys (Fig. 1) or (Fig. 2). Remove accessory
drive belt.
CLEANING
Clean all foreign debris from belt pulley grooves.
The belt pulleys must be free of oil, grease, and cool-
ants before installing the drive belt.

INSPECTION
New developments in belt technology allow the belt
to greatly increase its life expectancy. Unless the belt
exhibits one of the following conditions do not replace
the belt.
• Excessive wear
• Frayed cords
• Severe glazing
Poly-V Belt system may develop minor cracks
across the ribbed side (due to reverse bending). These
minor cracks are considered normal and acceptable.
Parallel cracks are not (Fig. 3).
NOTE: Do not use any type of belt dressing or
restorer on Poly-V Belts.
INSTALLATION
NOTE: When installing drive belt on the pulleys,
make sure that belt is properly routed and all
V-grooves make proper contact with pulley grooves.
(1) Install belt around all the pulleys except for
the generator pulley (Fig. 1) or (Fig. 2).
(2) Rotate accessory drive belt tensioner counter-
clockwise until accessory drive belt can be installed
on the generator pulley. Release spring tension onto
belt.
(3) Remove breaker bar from accessory drive belt
tensioner.
(4) Connect negative battery cable.
