Air Conditioning

The A/C refrigerant system is a clutch cycling orifice tube type. The system consists of the following components:
- A/C compressor
- A/C clutch
- A/C condenser core
- A/C evaporator core
- A/C charge port valve (high side)
- A/C charge port valve (low side)
- connecting refrigerant lines
- function selector switch
- suction accumulator

The refrigerant system operation is controlled by the following:
- A/C evaporator core orifice
- A/C cycling switch
- A/C compressor pressure relief valve
- A/C pressure cut-off switch.

The refrigerant system incorporates an A/C compressor controlled by an A/C cycling switch.

The A/C cycling switch senses A/C evaporator core pressure to control A/C compressor operation.

An A/C compressor pressure relief valve is installed in the A/C manifold and tube assembly (3.0L engine), on the discharge port of the A/C compressor (2.3L engine) to protect the refrigerant system against excessively high refrigerant pressures.

An A/C evaporator core orifice is installed in the condenser-to-evaporator line to meter the liquid refrigerant into the A/C evaporator core.
