DRIVE BELT
ON-VEHICLE INSPECTION
1. INSPECT DRIVE BELT'S INSTALLATION CONDITION
Check that the drive belt fits properly in the ribbed grooves.
2. INSPECT DRIVE BELT TENSION
Using a belt tension gauge, check the drive belt tension.
Belt tension gauge:
Nippondenso BTG-20 (95506-00020) or Borroughs
No. BT-33-73F
Drive belt tension:
New belt 160 ± 25 lbf
Used belt 100 ± 20 lbf
HINT:

ºNew beltº refers to a belt which has been used less than
5 minutes on a running engine.

ºUsed beltº refers to a belt which has been used on a run-
ning engine for 5 minutes or more.

After installing the drive belt, check that it fits properly in
the ribbed grooves.

COMPRESSOR
ON-VEHICLE INSPECTION
1. INSTALL MANIFOLD GAUGE SET
2. RUN ENGINE AT APPROX. 2,000 RPM
3. INSPECT COMPRESSOR
(a) High pressure gauge reading is not lower and low pressure gauge reading is not higher than normal.
(b) Check that the metallic sound.
(c) Check that the leakage from shaft seal.

EXPANSION VALVE
ON-VEHICLE INSPECTION
1. CHECK QUANTITY OF GAS DURING REFRIGERATION CYCLE
2. INSTALL MANIFOLD GAUGE SET
3. RUN ENGINE
Run the engine at 1,500 rpm for at least 5 minutes. Then check that the high pressure reading is 1.37 - 1.57
MPa (14 - 16 kgf/cm
2, 199 - 228 psi).
4. CHECK EXPANSION VALVE
If the expansion valve is faulty, the low pressure reading will drop to 0 kgf/cm
2, 0 psi), otherwise it is OK.
HINT:
When the low pressure drops to 0 kPa (0 kgf/cm
2, 0 psi), feel the receiver's IN and OUT sides for 0 tempera-
ture difference.

PRESSURE SWITCH
ON-VEHICLE INSPECTION
1. SET ON MANIFOLD GAUGE SET
(See page AC-21)
2. DISCONNECT CONNECTOR FROM PRESSURE
SWITCH
3. RUN ENGINE AT APPROX. 2,000 RPM
4. Magnetic Clutch Control:
INSPECT PRESSURE SWITCH OPERATION
(a) Connect the positive (+) lead from the ohmmeter to termi-
nal 4 and the negative (-) lead to terminal 1.
(b) Check continuity between terminals when refrigerant
pressure is charged, as shown in the illustration.
If operation is not as specified, replace the pressure switch.
5. Condenser Fan Control:
INSPECT PRESSURE SWITCH OPERATION
(a) Connect the positive (+) lead from the ohmmeter to termi-
nal 2 and the negative (-) lead to terminal 3.
(b) Check continuity between terminals when refrigerant
pressure is changed, as shown in the illustration.
If operation is not as specified, replace the pressure switch.
6. STOP ENGINE AND SET OFF MANIFOLD GAUGE SET
7. CONNECT CONNECTOR TO PRESSURE SWITCH
