age radiator cooling fins or water tubes during
removal.

INSTALLATION

(1) Slide radiator and fan module down into posi-

tion, seat the radiator assembly lower rubber isola-
tors in the mount holes provided.

equipped. Tighten mounting screws to 5 N·m (45 in.
lbs.).

(3) Install air conditioning line support bracket

and attaching screw to right side of radiator.

(4) Connect engine block heater wire, if equipped.
(5) Connect lower radiator hose and clamp.

(6) Install external transmission oil cooler line

support bracket and attaching screw to left side of
radiator (if equipped).

(7) Connect automatic transmission hoses; tighten

hose clamps to 2.5 N·m (22 in. lbs.).

(8) Install fan module.
(9) Connect fan motor electrical connection.
(10) 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.

(11) Install upper radiator crossmember. Refer to

Group 23, Body for procedure.

(12) Connect negative cable to auxiliary jumper

terminal.

(13) Fill cooling system with coolant. Refer to Cool-

ing System Refilling in this section.

(14) Operate engine until it reaches normal oper-

ating temperature. Check cooling system and auto-
matic transmission for correct fluid levels.

RADIATOR DRAINCOCK

REMOVAL

CAUTION: Plastic tanks, while stronger then brass
are

subject

to

damage

by

impact,

such

as

wrenches.

(1) Turn the draincock stem counterclockwise to

unscrew the stem. When the stem is unscrewed to
the end of the threads, pull the stem (Fig. 22) from
the radiator tank.

NOTE: To open draincock on vehicle equipped with
2.5L engine, use a 3/8 inch drive extension 3” long,
a 19mm socket with universal.

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 to 2.0-2.7 N·m (18-25 in. lbs.) torque.

REMOVAL AND INSTALLATION (Continued)

RADIATOR FAN, MOTOR AND SHROUD

REMOVAL

(1) Remove upper radiator crossmember. Refer to

Group 23, Body for procedure.

(2) Disconnect fan motor electrical connector.
(3) Remove fasteners attaching fan module to radi-

ator (Fig. 24).

(4) Remove fan module.

FAN SERVICE

There are no repairs to be made to the fan. If the

fan is warped, cracked, or otherwise damaged, it
must be replaced with only the recommended part
for adequate strength, performance and safety.

(1) To remove fan from motor shaft, bench support

the motor and motor shaft while removing the fan
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. 23). 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. 24).

(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.

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.
