Installation

1. Install compressor.

• Tighten the compressor fixing bolts to the

specified torque.

Torque: 19N•m (14 lb•ft)

2. Connect refrigerant line connector.

• Tighten the refrigerant line connector fixing bolts

to the specified torque.

Torque: 15N•m (11 lb•ft)

• O-rings cannot be reused. Always replace with

new ones.

• Be sure to apply new compressor oil to the

O-rings when connecting refrigerant lines.

3. Install serpentine belt.

• Move serpentine belt tensioner to loose side

using wrench, then install serpentine belt to
normal position.

4. Connect magnetic clutch harness connector.

New Compressor Installation

The new compressor is filled with 150cc (5.0fl.oz.)of
compressor oil and nitrogen gas. When mounting the
compressor on the vehicle, perform the following steps;

1. Gently release nitrogen gas from the new

compressor.
• Take care not to let the compressor oil flow out.
• Inspect O-rings and replace if necessary.

2. Turn the compressor several times by hand and

release the compressor oil in the rotor.

3. When installing on a new system, the compressor

should installed as it is. When installing on a used
system, the compressor should be installed after
adjusting the amount of compressor oil. (Refer to
