ator assembly lower rubber isolators in the mounting
holes provided in lower radiator support (Fig. 23).

clips on radiator. Install mounting screws and
tighten to 5 N·m (45 in. lbs.) (Fig. 25).
(3) Connect lower radiator hose and clamp.
(4) Install transmission cooler line bracket and
attaching fastener. Connect automatic transmission
hoses; torque hose clamps to 2.5 N·m (22 in. lbs.).
(5) Install fan module.
(6) Connect fan motor electrical connector.
(7) Connect engine oil cooler lines (if equipped).
(8) Install upper radiator hose. Align hose so it
does not interfere with the accessory drive belt or
engine. Position hose clamp so it will not interfere
with the hood liner.
(9) Install upper radiator support crossmember.
(10) Connect negative cable to remote jumper ter-
minal.
(11) Fill cooling system with coolant. Refer to Cool-
ing System Filling in this section.
(12) Operate engine until it reaches normal oper-
ating temperature. Check cooling system and auto-
matic transmission for correct fluid levels.
RADIATOR DRAINCOCK
REMOVAL
WARNING:
DO NOT REMOVE THE CYLINDER
BLOCK PLUG OR THE RADIATOR DRAINCOCK
WITH THE SYSTEM HOT AND UNDER PRESSURE
BECAUSE SERIOUS BURNS FROM COOLANT CAN
OCCUR.
CAUTION:
Use of pliers on draincock is not rec-
ommended. Damage may occur to part. Draincock
should not be removed unless leakage is observed.
(1) Turn the draincock stem counterclockwise to
unscrew the stem. When the stem is unscrewed to
the end of its threads, turn back 1/8 turn and pull
the stem (Fig. 26) from the radiator tank.
INSTALLATION
(1) Push the draincock assembly body into the
tank opening until it snaps into place.
(2) Tighten the draincock stem by turning clock-
wise until it stops.
COOLING FAN MODULE
REMOVAL
(1) Remove upper radiator crossmember. Refer to
Group 23, Body for procedure.
(2) Disconnect fan electrical connector.
(3) Remove fan module attaching fasteners and
clips (Fig. 27).

(4) Remove fan module by lifting upward to clear
radiator.
INSTALLATION
(1) Install fan module.
(2) Install mounting clips and fasteners.
(3) Connect fan module electrical connector.
(4) Install upper radiator crossmember.
ENGINE BLOCK HEATER
REMOVAL
(1) Raise vehicle on hoist.
(2) Detach power cord plug from heater (Fig. 28).
(3) Remove block heater attaching screw located
below heater terminals.
(4) Remove block heater from cylinder block.
INSTALLATION
(1) Thoroughly clean cylinder block heater cavity.
(2) Insert heater assembly into block such that
mounting hole is located below heater terminals.
(3) Install mounting screw and tighten to 12 N·m
(105 in. lb.).
(4) Attach power cord to heater.
CAUTION: To prevent damage, the power cord
must be secured in its retainer clips, and not posi-
tioned so it could contact linkages or exhaust man-
ifolds.
(5) Lower vehicle.
AIR CONDITIONING BELT—2.7L
REMOVAL
(1) Remove accessory drive belt. Refer to procedure
outlined in this section.
(2) Loosen BUT DO NOT REMOVE tensioner
locking bolt (Fig. 29).
(3) Insert 1/2” drive breaker bar into square open-
ing on belt tensioner. Rotate tensioner counterclock-
wise until belt can be removed from pulleys (Fig. 29).
(4) Slowly rotate tensioner clockwise to relieve
spring load.

SIONER LOCKING BOLT WITHOUT FIRST HOLDING
THE TENSIONER WITH A 1/2” DRIVE BREAKER
BAR, AS PERSONAL INJURY COULD RESULT.
NEW BELT
NOTE: Verify that torsion spring position is in the
new belt position before installing a NEW belt (Fig.
30). If torsion spring is not in the new belt position,
follow steps 1 – 7 to change the tensioner spring
from the USED belt position to the NEW belt posi-
tion.
(1) Insert a 1/2” drive breaker bar into the square
opening on the tensioner. Hold counterclockwise pres-
sure on tensioner while removing the locking bolt
(Fig. 29).
(2) Carefully release spring load of the torsion
spring on the tensioner.
(3) Remove pivot bolt, tensioner, and spring from
front timing cover.
(4) Insert spring arm into the NEW belt position
on the tensioner (Fig. 30).
(5) Install torsion spring, tensioner, and pivot bolt.
(6) Tighten pivot bolt to 28 N·m (250 in. lbs.).
(7) Using a 1/2” drive breaker bar, apply counter-
clockwise pressure until locking bolt can be installed.
(8) Rotate tensioner counterclockwise until the
NEW belt can be installed on pulleys. See (Fig. 31)
for belt routing.
(9) Release tensioner and remove socket wrench.
Belt is automatically adjusted with the tensioner’s
torsion spring.
(10) Tighten tensioner locking bolt to 28 N·m (250
in. lbs.) (Fig. 29).
(11) Install accessory drive belt.
USED BELT
NOTE: A “used belt” is considered having more
than 500 miles of service use.
NOTE: Perform steps 1 – 7 to change the tensioner
spring from the NEW belt position, to the USED belt
position.
(1) Insert a 1/2” drive breaker bar into the square
opening on tensioner. Hold counterclockwise pressure
on tensioner, while removing tensioner locking bolt
(Fig. 29).
(2) Carefully release the tension of spring on ten-
sioner.
(3) Remove pivot bolt, tensioner, and spring from
front cover.
(4) Insert spring into the used belt position on ten-
sioner bracket (Fig. 30).
(5) Install spring, tensioner bracket, and pivot
bolt.
(6) Tighten pivot bolt to 28 N·m (250 in. lbs.).
(7) Using a 1/2” drive breaker bar, apply counter-
clockwise pressure until locking bolt can be installed.
(8) Install the USED belt by rotating tensioner
counterclockwise until belt can be installed on pul-
leys. See (Fig. 31) for belt routing.
