REMOVAL AND INSTALLATION

SERVICE POINTS OF REMOVAL





1. REMOVAL OF COMPRESSOR DRIVE BELT
(1) Loosen bolt "A" for holding the tension pulley.
(2) Loosen bolt "B" for adjustment, and remove the compressor drive belt.

2. REMOVAL OF SUCTION HOSE
If the hoses or pipes are disconnected, cap the hoses or pipes with a blank plug to prevent entry of dust, dirt, and water.

6. REMOVAL OF COMPRESSOR
When doing this work, be careful not to spill the compressor oil.
For DOHC engines, remove the compressor with the compressor mounting bolt set in the compressor.

INSPECTION
- Checking for heat damage of the tension pulley.
- Check for excessive play or deflection of the tension pulley.
- Check for unusual wear of the tension pulley.
- Check for hardening of the air conditioning belt.
- Check for unusual wear or abrasion of the air conditioning belt.





OPERATION CHECK OF THE COMPRESSORS MAGNETIC CLUTCH
(1) Connect terminal (1) at the compressor side to the positive (+) terminal of the battery, and earth the negative (-) terminal of the battery to the compressor.
(2) The condition of the compressor's magnetic clutch can be considered satisfactory if the operation sound (a "click" sound) of the magnetic clutch can be heard when this check is made.





CHECK OF THE COMPRESSOR
(1) Connect terminal (1) at the compressor side to the positive (+) terminal of the battery, and ground the negative (-) terminal of the battery to the compressor.
(2) The condition of the compressor's magnetic clutch can be, considered satisfactory if the operation sound (a "click sound) of the magnetic clutch can be heard when this check is made.
Replace the magnet clutch if it is defective.
(3) With the magnetic clutch functioned, make sure that the compressor pulley turns when cranking by hand.

NOTE: If the cranking is performed with the starter. the compressor drive belt could be cut if it locks. Replace the compressor if it is defective.

SERVICE POINTS OF INSTALLATION

6. INSTALLATION OF COMPRESSOR
(1) If a new compressor is installed. first adjust the amount of oil according to the procedures described below. and then install the compressor.
1) Measure the amount [X cm3 (X fl.oz.)] of oil within the removed compressor.
2) Wipe away (from the new compressor) the amount of oil calculated according to the following formula and then install the new compressor.


New compressor oil amount 160 cm3 - X cm3 = Y cm3 (5.4 fl.oz. - X fl.oz."', Y fl.oz.)


170 cm3 - X cm3 = Y cm3 (5.7 ft.oz. - X ft.oz. = Y ft.oz.)

NOTE
(1) Y cm3 (Y fl.oz.) indicates the amount of oil in the refrigerant line. the condenser. the cooling unit, etc.
(2) When replacing the following parts at the same time as the compressor. subtract the rated oil amount of the each part from Y cm3 and discharge from the new compressor.

Compressor oil:
FREOL S-83 or SUNISO 5GS
SUN PAG56

Quantity:
Evaporator: 60 cm3 (2.0 fl.oz.)
Condenser: 15 cm3 (.5 fl.oz.)
Suction hose: 10 cm3 (.3 fl.oz.)
Receiver: 10 cm3 (.3 fl.oz.)

(2) For DOHC engines. install the compressor with the compressor mounting bolt set in the compressor.
