Compressor (For 1Vd-Ftv) Installation

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:

VDJ200L-GNMNZV, GNTNZV, GPMNZV:

(Oil capacity inside the new compressor and magnetic clutch: 140 + 15 cc (4.7 + 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)

Except VDJ200L-GNMNZV, GNTNZV, GPMNZV:

(Oil capacity inside the new compressor and magnetic clutch: 135 + 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)

NOTICE:

1. When checking the compressor oil level, follow the A/C system precautions.
   
2. 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.
   
3. If the volume of oil remaining in the removed compressor and magnetic clutch is too small, check for oil leakage.
   
4. Be sure to use ND-OIL 8 or equivalent for compressor oil.
   

Install the cooler compressor with the 4 bolts.

Torque:

24.5 N*m{250 kgf*cm, 18 ft.*lbf}

HINT:

Tighten the bolts in the order shown in the illustration.

Connect the connector.

Remove the attached vinyl tape from the cooler refrigerant suction hose.

Sufficiently apply compressor oil to a new O-ring and the fitting surface of the cooler compressor.

Compressor oil:

ND-OIL 8 or equivalent

Install the O-ring to the suction hose.

Connect the suction hose to the cooler compressor with the bolt.

Torque:

9.8 N*m{100 kgf*cm, 87 in.*lbf}

Remove the attached vinyl tape from the discharge hose.

Sufficiently apply compressor oil to a new O-ring and the fitting surface of the cooler compressor.

Compressor oil:

ND-OIL 8 or equivalent

Install the O-ring to the discharge hose.

Connect the discharge hose to the cooler compressor with the bolt.

Torque:

9.8 N*m{100 kgf*cm, 87 in.*lbf}

Install the No. 2 intake air connector pipe to the No. 2 inlet compressor elbow.

NOTICE:

Make sure there is no gap between the air pipe and hose stopper on the elbow side.

Install the bolt of the No. 2 intake air connector pipe.

Torque:

21 N*m{214 kgf*cm, 15 ft.*lbf}

NOTICE:

Do not excessively pull the air pipe towards the front of the engine.

Tighten the hose clamp on the elbow side.

Torque:

6.0 N*m{61 kgf*cm, 53 in.*lbf}

HINT:

1. Align the 2 protrusions of the air pipe and elbow.
   
2. Install the air pipe so that the protrusion on the pipe side is within the range of the protrusion on the elbow side.
   
3. After tightening, a gap between the air pipe and hose stopper on the elbow side is acceptable.
   
4. Make sure the direction of the hose clamp is as shown in the illustration.
   

w/ Intercooler:
Connect the vacuum hose.

Connect the No. 2 air cleaner pipe to the No. 2 intake air connector pipe.

Connect the ventilation hose to the oil separator.

Install the pipe with the bolt.

Torque:

21 N*m{214 kgf*cm, 15 ft.*lbf}

Tighten the hose clamp.

Torque:

6.3 N*m{64 kgf*cm, 56 in.*lbf}

Perform vacuum purging using a vacuum pump.

Charge refrigerant HFC-134a (R134a).

NOTICE:

1. Do not operate the cooler compressor before charging refrigerant as the cooler compressor will not work properly without any refrigerant, and will overheat.
   
2. Approximately 100g (3.53 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 the engine at less than 1850 rpm for 2 minutes or more after charging the refrigerant.

NOTICE:

Be sure to warm up the compressor when turning the A/C switch is on after removing and installing the cooler refrigerant lines (including the compressor), to prevent damage to the compressor.

After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.

Perform the operation under these conditions:

1. Stop the engine.
   
2. Secure good ventilation (the halogen leak detector may react to volatile gases other than refrigerant, such as evaporated gasoline or exhaust gas).
   
3. Repeat the test 2 or 3 times.
   
4. Make sure that some refrigerant remains in the refrigeration system. When compressor is off: approximately 392 to 588 kPa (4.0 to 6.0 kgf/cm², 57 to 85 psi).
   

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.
