REMOVAL SERVICE POINTS
<<A>> FLEXIBLE SUCTION HOSE/FLEXI-
BLE DISCHARGE HOSE DISCONNEC-
TION
CAUTION
As the compressor oil and receiver are highly
moisture absorbent, use a non-porous material
to plug the hose and nipples.
To prevent the entry of dust or other foreign bodies,
plug the dismantled hoses and compressor nipples.
<<B>> DRIVE BELT REMOVAL
The following operations will be needed due to the
serpentine drive system with the alternator drive belt
auto tensioner.
Pre-removal Operation
• Refrigerant Discharging (Refer to
Post-installation Operation
• Drive Belt Tension Adjustment (Refer to GROUP 11A,
On-vehicles Service
− Drive Belt Tension Check
).
• Refrigerant Charging (Refer to
).

1. Securely insert the spindle handle or ratchet
handle with a 12.7 mm insertion angle into the jig
hole of the alternator drive belt auto tensioner,
and turn the alternator drive belt auto tensioner
anti-clockwise until it hits the stopper.
CAUTION
To reuse the alternator drive belt, draw an arrow
indicating the rotating direction (clockwise) on
the back of the alternator drive belt using chalk.
2. Align hole A with hole B, insert an L-shaped
hexagon wrench, etc. to fix and then remove the
alternator drive belt.
<<C>> A/C COMPRESSOR REMOVAL
Take care not to spill any compressor oil when
removing the compressor.
INSTALLATION SERVICE POINT
>>A<< A/C COMPRESSOR INSTALLA-
TION
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 mL) of oil within the
removed compressor.
2. Drain (from the new compressor) the amount of
oil calculated according to the following formula,
and then install the new compressor.
New compressor oil amount = 120 mL
120 mL
−X mL = Y mL
NOTE: Y mL indicates the amount of oil in the
refrigerant line, the condenser, the evaporator,
etc.
NOTE: When replacing the following parts at the
same times as the compressor, subtract the rated
oil amount of the each part from Y mL and dis-
charge from the new compressor.
Quantity:
• Evaporator: 60 mL
• Condenser: 15 mL
• Suction hose: 10 mL
• Receiver: 10 mL

OPERATION CHECK
Connect the compressor connector terminal to the
battery positive (+) terminal and earth the battery’s
negative (
−) terminal to the compressor unit. At that
time, the magnetic clutch should make a definite
operating sound.
