A / C CONDENSER ASSEMBLY
INSPECTION
Check
a) condenser fins for blockage
b) condenser fittings for leakage
c) condenser fins for damage
Clogged condenser fins should be washed with water, and should
be dried with compressed air.
CAUTION:
Be careful not to damage condenser fins. If condenser fin is
bent, straighten it by using a screwdriver or pair of pliers. If
any leakage is found from fitting or tube, repair or replace
condenser.
REMOVAL
1) Disconnect negative (±) cable at battery.
2) Recover refrigerant by using recovery and recycling equipment.
Be sure to follow the instruction manual for the equipment.
The amount of compressor oil removed must be measured and
the same amount added to the system.
3) Remove front bumper assembly and remove lower stay (1) if
equipped (Refer to Section 9 ªBODY SERVICEº).
4) Disconnect compressor discharge hose (1) from condenser in-
let fittings.
CAUTION:
As soon as above hose and pipe are disconnected, cap
opened fittings so that moisture and dust do not enter
condenser.
