Condenser Installation

Using pliers, install the cooler dryer.

Apply a sufficient amount of compressor oil to the contact surfaces of a new O-ring and the cap.

Compressor:

ND-OIL 8 or equivalent

Install the O-ring to the cap.

Using a 14 mm socket hexagon wrench, install the cap to the modulator.

Torque:

2.9 N*m{30 kgf*cm, 26 in.*lbf}

Install the cooler condenser assembly with the 3 bolts as shown in the illustration.

Torque:

for bolt A:

5.4 N*m{55 kgf*cm, 48 in.*lbf}

for bolt B:

4.4 N*m{44 kgf*cm, 39 in.*lbf}

Remove the attached vinyl tape from the hose and the connecting part of the cooler condenser assembly.

Sufficiently apply compressor oil to a new O-ring and the fitting surface of the discharge hose sub-assembly joint.

Compressor:

ND-OIL 8 or equivalent

Install the O-ring to the discharge hose sub-assembly.

Connect the discharge hose sub-assembly to the cooler condenser assembly with the bolt.

Torque:

5.4 N*m{55 kgf*cm, 48 in.*lbf}

NOTICE:

1. When tightening the bolt, do not allow any tools to contact the pipe.
   
2. When tightening the bolt, hold a part of the pipe near the connector.
   

Install the 2 bolts and No. 2 cooler condenser bracket.

Install the 2 bolts and No. 1 cooler condenser bracket.

Remove the attached vinyl tape from the pipe and the connecting part of the cooler condenser assembly.

Sufficiently apply compressor oil to a new O-ring and the fitting surface of the air conditioning tube assembly joint.

Compressor:

ND-OIL 8 or equivalent

Install the O-ring to the air conditioning tube assembly.

Connect the air conditioning tube assembly to the cooler condenser assembly with the bolt.

Torque:

5.4 N*m{55 kgf*cm, 48 in.*lbf}

NOTICE:

1. When tightening the bolt, do not allow any tools to contact the pipe.
   
2. When tightening the bolt, hold a part of the pipe near the connector.
   

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 100 g (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.
