RADIATOR
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 side 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.
COOLING SYSTEM CLEANING/FLUSHING
CLEANING
CAUTION: Internal
radiator
pressure
must
not
exceed 138 kPa (20 psi) as damage to radiator may
result.
Reverse flushing of cooling system is the forcing of
water through the cooling system. This is done using
air pressure in the opposite direction of normal cool-
ant flow. It is usually only necessary with very dirty
systems with evidence of partial plugging.
(1) Drain cooling system. Remove thermostat hous-
ing and thermostat. Install thermostat housing.
(2) Connect a suitable cooling system flusher and
follow instructions supplied with flusher.
INSPECTION
After performing a flush procedure, inspect all
hoses, clamps and connections for deterioration and
leaks. Inspect radiator and heater core for leaks.
TRANSMISSION OIL COOLER
CLEANING
For cooler flushing procedure, refer to Group 21,
Transaxle.
Clean debris from cooling fins on external (air-to-
oil) cooler as necessary.
INSPECTION
Inspect all hoses, tubes, clamps and connections for
leaks, cracks, or damage. Replace as necessary. Use
only approved transmission oil cooler hoses that are
molded to fit the space available.
Inspect external coolers for leaks, loose mounts, or
damage. Replace as necessary.
