(11) Lift condenser upward enough to disengage
upper mounting clips. Allow condenser to rest on
lower radiator crossmember. It is not necessary to
discharge the air conditioning system.
(12) Radiator can now be lifted from engine com-
partment. Care should be taken not to damage
radiator cooling fins or water tubes during
removal.
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) Position radiator into engine compartment.
Seat the radiator assembly lower rubber isolators
into the mounting holes in radiator lower support
(Fig. 15).
(2) Attach air conditioning condenser to mounting
clips on radiator. Install mounting screws and
tighten to 5 N·m (45 in. lbs.) (Fig. 17) or (Fig. 18).
(3) Install the radiator lower hose and clamp.
(4) Install the transmission cooler line bracket and
attaching fastener (Fig. 17) or (Fig. 18). Connect
automatic transmission hoses and torque hose
clamps to 3 N·m (28 in. lbs.).
(5) Install the radiator fan. (Refer to 7 - COOL-
ING/ENGINE/RADIATOR FAN - INSTALLATION)
(6) Connect radiator fan motor electrical connector.
(7) Connect engine oil cooler lines (if equipped).
Torque lines to 18 N·m (160 in. lbs.).
(8) Install the radiator upper 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.
(9) Install the radiator upper support crossmem-
ber. (Refer to 23 - BODY/EXTERIOR/GRILLE OPEN-
ING REINFORCEMENT - INSTALLATION)
(10) Connect negative cable to remote jumper ter-
minal.
(11) Fill cooling system with coolant. (Refer to 7 -
COOLING - STANDARD PROCEDURE)
(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 recom-
mended. Damage may occur to part. Draincock
should not be removed unless leakage is observed.
(1) Drain the cooling system (Refer to 7 - COOL-
ING - STANDARD PROCEDURE).
(2) Turn the draincock stem counterclockwise 180
degrees to the 9:00 o'clock position.
(3) With the stem at the 9:00 o'clock position, pull
the draincock assembly from the radiator tank (Fig.
19).
INSTALLATION
(1) Inspect the draincock body and O-ring for dam-
age. Replace as necessary.
