The compressor is a large roundish type unit mounted on the engine. The compressor has usually two hoses attached to it.
- Turn the engine ON and let it idle for ten minutes with the air conditioning switched ON.
- Turn the engine OFF and disconnect the negative battery cable.
- Safely discharge the refrigerant from the system, this must be performed by a properly trained and certified mechanic in a facility equipped with refrigerant recovery/recycling equipment that meets SAE standards.
- Unplug the compressor clutch wire.
- Disconnect the two refrigerant lines at the compressor. Cap the open fitting immediately to keep moisture out of the system. Discard the old O-rings.
- Remove the fan shroud, then remove the air conditioning drive belt.
- For 3VZ-E engines, remove the power steering pump. On some models you will need to remove the engine undercover.
- Remove the mounting bolts and lift out the compressor. The compressor is heavy; support it before removing the retaining bolts.
- Remove the compressor bracket.
- Install the compressor bracket to the unit.
- Install the compressor, then tighten the mounting bolts to 18 ft. lbs. (25 Nm).
- Install the drive belt and adjust the tension.
- Install new O-rings to the A/C lines and lubricate them with ND-Oil 8 or an equivalent refrigerant oil. Connect the two refrigerant lines to the compressor. Tighten the suction line to 7-24 ft. lbs. (9-32 Nm) and the discharge line to 7-16 ft. lbs. (9-22 Nm).
- Connect the compressor clutch wire.
- Install the power steering pump or engine undercover if removed.
- Connect the negative battery cable.
