ADJUST COMPRESSOR OIL
When replacing the compressor and magnetic clutch with a new one, gradually discharge the refrigerant gas from the service valve, and drain the following amount of oil from the new compressor and magnetic clutch before installation.
| Standard (Except G.C.C) |
|---|
| (Oil capacity inside the new compressor and magnetic clutch: 130 + 15 cc (4.6 + 0.51 fl. oz.) ) - (Remaining oil amount in the removed compressor and magnetic clutch) = (Oil amount to be removed from the new compressor when replacing) |
| Standard (G.C.C) |
|---|
| (Oil capacity inside the new compressor and magnetic clutch: 170 + 15 cc (5.7 + 0.51 fl. oz.) ) - (Remaining oil amount in the removed compressor and magnetic clutch) = (Oil amount to be removed from the new compressor when replacing) |
Note
When checking the compressor oil level, observe the A/C system's precautions.
If a new compressor and magnetic clutch is installed without removing some oil remaining in the pipes of the vehicle, the oil amount will be too large. This prevents heat exchange in the refrigerant cycle and causes refrigerant failure.
If the volume of oil remaining in the removed compressor and magnetic clutch is too small, check for oil leakage.
Be sure to use ND-OIL 8 or equivalent for compressor oil.
INSTALL WITH PULLEY COMPRESSOR ASSEMBLY
Using an E8 "TORX" socket wrench, install the with pulley compressor assembly with the 2 stud bolts.
Install the 2 bolts and 2 nuts.
Note
Tighten the nuts and bolts in the order shown in the illustration to install the with pulley compressor assembly.
Connect the connector.
CONNECT DISCHARGE HOSE SUB-ASSEMBLY
Remove the attached vinyl tape from the hose.
Sufficiently apply compressor oil to a new O-ring and the fitting surface of the with pulley compressor assembly.
| Compressor oil |
|---|
| ND-OIL 8 or equivalent |
Install the O-ring to the discharge hose sub-assembly.
Connect the discharge hose sub-assembly to the with pulley compressor assembly with the bolt.
CONNECT SUCTION TUBE SUB-ASSEMBLY B
Remove the attached vinyl tape from the tube sub-assembly B.
Sufficiently apply compressor oil to a new O-ring and the fitting surface of the with pulley compressor assembly.
| Compressor oil |
|---|
| ND-OIL 8 or equivalent |
Install the O-ring to the cooler suction tube sub-assembly B.
Connect the suction tube sub-assembly B to the with pulley compressor assembly with the bolt.

INSTALL COWL TOP VENTILATOR LOUVER
for LHD:
Install the 6 clips and cowl top ventilator louver RH.
Note
If the cowl top ventilator louver RH is not properly installed, water may leak into the engine room and cause malfunctions. Therefore, make sure the cowl top ventilator louver RH is installed properly.
for RHD:
Install the 6 clips and cowl top ventilator louver LH.
Note
If the cowl top ventilator louver LH is not properly installed, water may leak into the engine room and cause malfunctions. Therefore, make sure the cowl top ventilator louver LH is installed properly.
ADD COMPRESSOR OIL
When performing work on air conditioning parts, follow the oil guidelines below in order to protect the cooler compressor.
| Part and Condition | Oil Level (cc) | Work Procedure | |
|---|---|---|---|
| Compressor replacement | -100 to -120 | Drain oil from new compressor | |
| Condenser replacement | 35 to 55 | Fill oil into replacement part | |
| Evaporator replacement | 40 to 60 | ||
| A/C pipe replacement | High pressure | 5 to 25 | |
| Low pressure | |||
| When discharging refrigerant gas quickly | 30 to 50 | While applying vacuum, use manifold gauge to fill oil from low pressure side valve | |
CHARGE REFRIGERANT
Perform vacuum purging using a vacuum pump.
Charge refrigerant HFC-134a (R134a).
| Standard | |||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
|
| *a | Amount to be charged | *b | Charge 100 g (3.53 oz) |
| *c | Mean value in proper range | *d | Point where bubbles disappear |
| *e | Overcharged | *f | Pressure |
| *g | Sub-cool system | *h | Refrigerant amount |
Note
Do not operate the cooler compressor before charging refrigerant as the cooler compressor will not work properly without any refrigerant, and will overheat.
Approximately 200 g (7.05 oz.) of refrigerant may need to be charged after bubbles disappear. The refrigerant amount should be checked by measuring its quantity, and not with the sight glass.
WARM UP ENGINE
Warm up the engine at less than 1850 rpm for 2 minutes or more after charging the refrigerant.
Note
Be sure to warm up the compressor when turning the A/C switch ON after removing and installing the cooler refrigerant lines (including the compressor) to prevent damage to the compressor.
CHECK FOR LEAKAGE OF REFRIGERANT
After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.
Perform the operation under these conditions:
Stop the engine.
Secure good ventilation (the halogen leak detector may react to volatile gases other than refrigerant, such as evaporated gasoline or exhaust gas).
Repeat the test 2 or 3 times.
Make sure that some refrigerant remains in the refrigeration system.
Tech Tips
When compressor is off:
approximately 392 to 588 kPa (4 to 6 kgf/cm2, 57 to 85 psi)
| *1 | Halogen Leak Detector |
| *a | Check for Leakage |
Using a halogen leak detector, check the refrigerant line for leakage.
If a gas leak is not detected on the drain hose, remove the blower motor control (blower resistor) from the cooling unit. Insert the halogen leak detector sensor into the unit and perform the test.
Disconnect the connector and wait for approximately 20 minutes. Bring the halogen leak detector close to the pressure switch and perform the test.
INSPECT FOR EXHAUST GAS LEAK
If gas is leaking, tighten the areas necessary to stop the leak. Replace the damaged parts as necessary.
