RADIATOR (Continued)

CLEANING

Clean radiator fins are necessary for good heat
transfer. The radiator and air conditioning fins
should be cleaned when an accumulation of debris
has occurred. With the engine cold, apply cold water
and compressed air to the back (engine side) of the
radiator to flush the radiator and/or A/C condenser of
debris.

INSPECTION

Inspect the radiator tanks for cracks, broken or
missing fittings also inspect the joint where the
tanks seam up to the radiator core for signs of leak-
age and/or deteriorating seals.
Inspect radiator core for corroded, bent or missing
cooling fins. Inspect the core for bent or damaged
cooling tubes.

INSTALLATION

(1) Non-Turbo Vehicles: Install the lower air seal
to radiator (Fig. 34).
NOTE: Turbocharger Equipped Vehicles: When low-
ering radiator, make sure lower radiator pins
engage properly through charge air cooler locating
tabs (Fig. 37).

(2) Position radiator into mounting position.
(3) Position A/C condenser against radiator. Hand
start fasteners.
(4) Turbocharger Equipped Vehicles: Install
fasteners attaching charge air cooler to radiator.
Torque fasteners to 8 N·m (70 in. lbs.) (Fig. 35).
(5) Install radiator fan/shroud assembly. Hand
start fasteners.
ENGINE - 2.0/2.4L DOHC
(6) Torque all condenser fasteners to 8 N·m (70 in.
lbs.).
(7) Torque all radiator fan fasteners to 6 N·m (55
in. lbs.).
(8) Non-Turbo Vehicles with Automatic Trans-
mission: Install fasteners attaching transmission oil
cooler to radiator. Torque fasteners to 8 N·m (70 in.
lbs.).
(9) Raise vehicle on hoist.
(10) Non-Turbo Vehicles: Connect the lower air
seal to the side air seals (Fig. 34).
(11) Connect lower radiator hose (Fig. 33). Align
the hose and position the clamp so it will not inter-
fere with engine components.
(12) Connect the radiator fan electrical connector.
(13) Turbocharger Equipped Vehicles: Connect
the power steering hoses.
(14) Close radiator draincock.
(15) Lower vehicle.
(16) Turbocharger equipped vehicles: Inspect
radiator inlet neck o-ring. Replace if necessary.
Install radiator inlet neck. Torque fasteners to 6 N·m
(55 in. lbs.).
(17) Connect upper radiator hose (Fig. 33). Align
the hose and position the clamp to prevent interfer-
ence with the engine or hood.
(18) Install upper radiator closure panel and cen-
ter brace (Refer to 23 - BODY/EXTERIOR/RADIA-
TOR CLOSURE PANEL - INSTALLATION).
(19) Install grille (Refer to 23 - BODY/EXTERIOR/
GRILLE - INSTALLATION).
(20) Install battery tray and battery.
(21) Connect positive battery cable. Connect nega-
tive battery cable.
(22) Install air cleaner housing assembly.
(23) Fill cooling system with coolant (Refer to 7 -
COOLING/ENGINE - STANDARD PROCEDURE).
(24) Operate engine until it reaches normal oper-
ating temperature. Check cooling system for correct
fluid level.
(25) Turbocharger Equipped Vehicles: Check
power steering fluid level. Fill as needed.
