(2) Raise vehicle on hoist.
(3) Remove the two (2) push clips attaching lower
air shield to engine cradle. Remove air shield.
(4) Loosen tensioner adjusting bolt until the belt
can be removed.
INSTALLATION
(1) Install generator/power steering belt.
NOTE: Use Special Tool 7198, Belt Tension Gauge
to obtain proper tension on accessory drive belt.
Refer to Belt Tension Chart.
(2) Tighten adjusting bolt until the specified ten-
sion is obtained.
(3) Install lower air shield and attaching push
clips.
(4) Lower vehicle.
(5) Tighten tensioner pulley locking nut.
Generator/Power Steering Belt Tension Adjustment
Loosen the tensioner pulley locking nut and adjust
belt tension by tightening adjusting bolt. Use Belt
Tension Gauge and refer to Belt Tension Chart for
specifications. Torque pulley nut to 54 N·m (40 ft.
lbs.) after adjustment.
CLEANING AND INSPECTION
WATER PUMP
CLEANING
Clean all gasket mating surfaces as necessary.
INSPECTION
Inspect and replace the water pump if it has any of
the following defects:
(1) Damage or cracks on the pump body.
(2) Coolant leaks; if the seal is leaking, this will be
evident by traces of thick deposits of dried glycol run-
ning down the pump body (3.2/3.5L), pump weep pas-
sage (2.7L) (Fig. 47), and components below. A thin
black stain below pump weep hole/passage is consid-
ered normal operation.
(3) Impeller rubs inside of cylinder block (2.7L) or
timing belt cover (3.2/3.5L) engines.
(4) Excessively loose or rough turning bearing.
NOTE: It is normal for the water pump to weep a
small amount of coolant from the weep hole (black
stain on water pump body). Do not replace the
water pump if this condition exists. Replace the
water pump if a heavy deposit or a steady flow of
engine coolant is evident on water pump body (3.2/
3.5L) or from the weep passage (2.7L) (Fig. 47). This
indicates a shaft seal failure and pump must be
replaced. Be sure to perform a thorough analysis
before replacing water pump.
ACCESSORY DRIVE BELTS
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.
