HOSE CLAMPS
DESCRIPTION - HOSE CLAMPS
The cooling system uses constant tension spring
type hose clamps. If a spring type clamp replacement
is necessary, replace with the original Mopar
t equip-
ment spring type clamp.
Vehicles equipped with a 2.7L engine, use unique
“Low Profile” type constant tension hose clamps at
the coolant outlet connector hoses.
CAUTION: A number or letter is stamped into the
tongue of constant tension clamps. If replacement
is necessary, use only an original equipment clamp
with matching number or letter (Fig. 22) or (Fig. 23).
OPERATION - HOSE CLAMPS
The constant tension type hose clamps maintain
constant clamping force on the hose connections as
the temperature of the cooling system rises and falls.
Worm gear type hose clamps may not have sufficient
clamping
force
in
colder
weather
conditions
if
installed during warm weather.
To remove a spring type hose clamp, use Special
Tool 8495 Hose Clamp Pliers, or equivalent, (Fig. 24)
to compress the hose clamp.

for use on the “Low Profile” type hose clamps used
at the coolant outlet connector hoses on the 2.7L

styles of constant tension type hose clamps.
RADIATOR
REMOVAL
(1) Disconnect
negative
cable
from
auxiliary
jumper terminal.
WARNING: DO NOT REMOVE PRESSURE CAP OR
ANY HOSE WITH THE SYSTEM HOT AND UNDER
PRESSURE
BECAUSE
SERIOUS
BURNS
FROM
COOLANT CAN OCCUR.
(2) Drain cooling system (Refer to 7 - COOLING/
ENGINE - STANDARD PROCEDURE).
(3) Remove upper radiator crossmember (Fig. 25).
CAUTION: Plastic tanks, while stronger than brass
are
subject
to
damage
by
impact,
such
as
wrenches.
(4) Disconnect the radiator fan electrical connector.
(5) Remove radiator fan.
(6) Disconnect hoses from radiator.
(7) Remove screw that holds support bracket for
transmission cooler tubes at left side of radiator (if
equipped).
CAUTION: Avoid bending the condenser inlet tube.
Care should be taken not to damage radiator or
condenser cooling fins.
(8) Remove the air conditioning condenser attach-
ing screws located at the front of the radiator (Fig.
26). Disengage AC condenser from radiator. It is not
necessary to discharge the air conditioning system to
remove radiator.
(9) Radiator can now be lifted free from engine
compartment. Care should be taken not to dam-
age radiator or condenser cooling fins 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) Slide radiator into position and seat the radia-
tor assembly lower rubber isolators in the mount
holes.
(2) Attach air conditioning condenser to radiator.
Tighten mounting screws to 5 N·m (45 in. lbs.).
(3) Install transmission oil cooler tube support
bracket and attaching screw to left side of radiator.
Tighten mounting screw to 5 N·m (45 in. lbs.).
(4) Connect hoses to radiator.
(5) Install radiator fan.
(6) Connect radiator fan electrical connector.
(7) Install upper radiator crossmember.
(8) Connect negative cable to auxiliary jumper ter-
minal.
(9) Fill cooling system(Refer to 7 - COOLING/EN-
GINE - STANDARD PROCEDURE).
RADIATOR DRAINCOCK
REMOVAL
CAUTION: Use of pliers on draincock is not recom-
mended. Damage may occur to radiator or drain-
cock.
NOTE: It is not necessary to remove draincock dur-
ing a routine coolant drain.
(1) Drain the cooling system (Refer to 7 - COOL-
ING/ENGINE - STANDARD PROCEDURE).
(2) Open the draincock by turning it counterclock-
wise until it stops.
(3) Turn the draincock back (clockwise) 1/8 turn.
(4) Pull the draincock (Fig. 27) from the radiator
tank.
INSTALLATION
(1) Align draincock stem to radiator tank opening.
(2) Push draincock into the radiator tank opening.
(3) Tighten the draincock by turning clockwise
until it stops.
(4) Fill the cooling system (Refer to 7 - COOLING/
ENGINE - STANDARD PROCEDURE).
PRESSURE CAP
DESCRIPTION
CAUTION: Vehicles equipped with 2.0L/2.4L engines
use a different pressure cap than vehicles equipped
with 2.7L engines. The pressure caps are NOT inter-
changeable. Verify proper pressure cap part num-
ber.
The cooling system is equipped with a pressure cap
that releases built up pressure, maintaining a range
of 97-124 kPa (14-18 psi).
There is also a vent valve in the center of the cap.
This valve also opens when coolant is cooling and
contracting, allowing coolant to return to radiator
from coolant reserve/recovery system container by
vacuum through connecting hose. If valve is stuck
shut, the radiator hoses will be collapsed on
cool down. Clean the vent valve (Fig. 28) to
ensure proper sealing when boiling point is
reached.
