REMOVAL
WARNING: RISK OF INJURY TO SKIN AND EYES
FROM SCALDING COOLANT. DO NOT OPEN COOL-
ING SYSTEM UNLESS TEMPERATURE IS BELOW
90°C (194°F). OPEN CAP SLOWLY TO RELEASE
PRESSURE. STORE COOLANT IN APPROVED AND
APPROPRIATELY
MARKED
CONTAINER.
WEAR
PROTECTIVE GLOVES, CLOTHING AND EYE WEAR.
NOTE: Constant tension hose clamps are used on
most vehicles. When removing or installing clamps
use tools designed for servicing these types of
clamps. A number or letter is stamped on the
clamp. If replacement is required use only original
equipment clamps with a matching letter or number.
NOTE: When removing the radiator, note the loca-
tion of the rubber radiator-to-body air seals. These
seals are used to prevent overheating and must
remain in there original positions.
Do Not waste usable coolant. If solution is clean,
drain into a clean container for reuse.
(1) Disconnect negative battery cable.
(2) Drain coolant from radiator (Refer to 7 -
COOLING/ENGINE/COOLANT - STANDARD PRO-
CEDURE).
NOTE: When ever the high pressure line fittings are
removed from the hydraulic fan drive the O-rings
must be replaced.
(3) Disconnect both pressure lines at hydraulic fan
drive (Refer to 7 - COOLING/ENGINE/RADIATOR
FAN - REMOVAL).
(4) Disconnect low pressure return hose at hydrau-
lic fan drive(Refer to 7 - COOLING/ENGINE/RADIA-
TOR FAN - REMOVAL).
(5) Disconnect fan electrical connector and set
aside.
(6) Remove lower, upper radiator, and coolant
pressure container hoses from radiator.
NOTE: The lower portion of the radiator is equipped
with two alignment dowel pins that are seated in
rubber grommets. These grommets are pressed into
the lower cross member and must remain present
to prevent radiator tank damage.
(7) Remove radiator retaining bolts, and carefully
remove coolant module assembly from vehicle (Fig.
15).
(8) Separate coolant fan from 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.
