INSTALLATION
(1) Position fan shroud over the fan blades rear­
ward towards engine.
(2) Install rubber insulators to alignment dowels at
lower part of radiator.
(3) Lower the radiator into position while guiding
the two alignment dowels into lower radiator sup­
port. Different alignment holes are provided in the
lower radiator support for each engine application.
(4) Install two upper radiator mounting bolts.
Tighten bolts to 11 N-m (95 in. lbs.) torque.
(5) 3.9L ¥-6 or 5.2L/5.9L V-8 Engines: Position the
rubber shields to the sides of radiator. Install the
plastic clips retaining the rubber shields to the sides
of radiator.
(6) Connect both radiator hoses. Refer to previous
CAUTION and install hose clamps.
(7) If equipped, connect transmission oil cooler
lines to radiator tank. Refer to Group 21, Transmis­
sions for procedures.
(8) Install windshield washer reservoir tank. Refer
to Group 8K.
(9) Position fan shroud to flanges on sides of radi­
ator. Install fan shroud mounting bolts (Fig. 64).
Tighten bolts to 6 N-m (50 in. lbs.) torque.
(10) Diesel Engines: Install metal clips to top of
fan shroud.
(11) All engines: Install coolant reserve/overflow
tank hose to radiator filler neck nipple.
(12) All Engines Except 8.0L V-10: Install coolant
reserve/overflow tank to fan shroud (fits into T-slots
on shroud).
(13) Connect throttle cable to fan shroud.
(14) Install negative battery cable(s) to battery(s).
(15) Diesel Engine: Install positive battery cable to
top of radiator. Tighten radiator-to-battery cable
mounting nuts.
(16) Position heater controls to full heat position.
(17) Fill cooling system with coolant. Refer to Re­
filling Cooling System in this group.
(18) Operate engine until it reaches normal tem­
perature. Check cooling system and automatic trans­
mission (if equipped) fluid levels.
RADIATOR CLEANING
The radiator and air conditioning fins should be
cleaned when an accumulation of bugs, leaves etc.
has occurred. Clean radiator fins are necessary for
good heat transfer. 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 con­
denser of debris.
COOLING SYSTEM HOSES
Rubber hoses route coolant to and from the radia­
tor, intake manifold and heater core. Radiator lower
hoses are spring-reinforced to prevent collapse from
water pump suction at moderate and high engine
speeds.
Inspect the hoses at regular intervals. Replace
hoses that are cracked, feel brittle when squeezed or
swell excessively when system is pressurized. The
use of molded replacement hoses is recommended.
When performing a hose inspection, inspect radiator
lower hose for proper position and condition of
spring.
