retaining clip, so that the shaft and motor will not be
damaged by excessive force. Surface burr removal
may be required to remove fan from motor
shaft (Fig. 43). Do not permit the fan blades to
touch the bench.
(2) To install fan on motor shaft, slide the fan over
the shaft. Support motor and shaft while installing
fan retaining clip.
FAN SHROUD
All vehicles have fan shrouds to improve fan air
flow efficiency.
The shroud supports the electric fan motor and
fan.
FAN MOTOR SERVICE
(1) Remove the motor fasteners from support.
Remove motor from support.
(2) Reverse the above procedure for Installation.
Tighten the short fan motor fasteners to 3 N·m (25
in. lbs.) and tighten the tall fan motor fasteners to 5
N·m (45 in. lbs.).
INSTALLATION
(1) Install fan module to radiator. Tighten shroud
to radiator fasteners to 7.5 N·m (65 in. lbs.) (Fig. 44).
(2) Connect fan motor electrical connector. For
wiring diagrams of fan motor systems, refer to
Group 8W, Wiring Diagrams.
(3) Install upper radiator crossmember. Refer to
Group 23, Body for procedure.
ENGINE BLOCK HEATER
REMOVAL
(1) Drain coolant from radiator and cylinder block.
Refer to Cooling System Drain, Clean, Flush and
Refill of this section for procedure.
(2) Detach power cord plug from heater.
(3) Loosen screw in center of heater. Remove
heater assembly.
INSTALLATION
(1) Thoroughly clean core hole and heater seat
(Fig. 45).
(2) Insert heater assembly with electrical connec-
tor position at the top of the core hole.
(3) With heater seated, tighten center screw
securely to assure a positive seal.
(4) Fill cooling system with coolant to the proper
level, vent air, and inspect for leaks. Pressurize sys-
tem with Radiator Pressure Tool before looking for
leaks.
The power cord must be secured in its retainer
clips, and not positioned so it could contact linkages
or exhaust manifolds and become damaged.
ACCESSORY DRIVE BELTS—2.0/2.4L ENGINES
AIR CONDITIONING COMPRESSOR AND
GENERATOR BELT
(1) Loosen T-Bolt locking nut A and pivot bolt B to
remove and install Poly V belt and/or adjust belt ten-
sion (Fig. 46).
(2) Tighten adjusting bolt to adjust belt tension to
specification shown in Belt Tension Chart.
(3) Tighten T-Bolt locking nut A and pivot bolt B to
54 N·m (40 ft. lbs.) (Fig. 46).
POWER STEERING PUMP BELT
(1) From the top of the vehicle loosen pivot bolt C.
(2) From under the vehicle loosen locking bolts D
and E (Fig. 47).
(3) Install the belt. Adjust belt tension with 1/2 in.
