(3) To duplicate a high-ambient temperature condi-
tion (high head pressure), restrict the air flow
through the condenser. Install a manifold gauge set
to be certain that the discharge pressure does not
exceed 2760 kPa (400 psi).
(4) Check the refrigerant system plumbing for
incorrect routing, rubbing or interference, which can
cause unusual noises. Also check the refrigerant lines
for kinks or sharp bends that will restrict refrigerant
flow, which can cause noises. (Refer to 24 - HEAT-
ING & AIR CONDITIONING/PLUMBING - CAU-
TION)
(5) If the noise is from opening and closing of the
high pressure relief valve, evacuate and recharge the
refrigerant system. (Refer to 24 - HEATING & AIR

A/C CONDENSER
DESCRIPTION
The condenser is located in the air flow in front of
the engine cooling radiator. The condenser is a heat
exchanger that allows the high-pressure refrigerant
gas being discharged by the compressor to give up its
heat to the air passing over the condenser fins.
OPERATION
When the refrigerant gas gives up its heat, it con-
denses. When the refrigerant leaves the condenser, it
has become a high-pressure liquid refrigerant. Thevolume of air flowing over the condenser fins is crit-
ical to the proper cooling performance of the air con-
ditioning system. Therefore, it is important that
there are no objects placed in front of the radiator
grille openings in the front of the vehicle or foreign
material on the condenser fins that might obstruct
proper air flow. Also, any factory-installed air seals or
shrouds must be properly reinstalled following radia-
tor or condenser service.
The condenser cannot be repaired and, if faulty or
damaged, it must be replaced.

erant line fittings.
(4) Disconnect the liquid line (Left-Hand Drive) or
liquid line jumper (Right-Hand Drive) refrigerant
line fitting at the condenser outlet. (Refer to 24 -

Install plugs in, or tape over all of the opened refrig-
erant line fittings.
(5) Remove the radiator and the condenser from
the vehicle as a unit. Refer to Cooling for the proce-
dures.
(6) Remove the two nuts that secure the condenser
studs to the upper brackets of the radiator (Fig. 6).
(7) Slide the condenser down from the radiator far
enough for the condenser studs to clear the upper
radiator bracket holes, and for the lower condenser
bracket holes to clear the dowel pins on the bottom of
the radiator.
(8) Remove the condenser from the radiator.
