On-vehicle inspection

1. INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET

(a) This method uses a manifold gauge set to locate problem areas. Read the manifold gauge pressure when these conditions are established.

Test conditions:

INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET

Refrigerant

(1) Normally functioning refrigeration system

Gauge reading

(2) The A/C system periodically changes between normal and improper function due to moisture in the refrigerant system.

Refrigerant

(3) The A/C system does not function effectively due to insufficient cooling.

Refrigerant

(4) The A/C system does not function effectively due to poor circulation of the refrigerant.

Refrigerant

(5) The A/C system does not function intermittently because the refrigerant does not circulate.

Refrigerant

(6) The A/C system does not function effectively due to overcharged refrigerant or insufficient cooling of the condenser.

Refrigerant

Refrigerant

(7) The A/C system does not function due to air in the refrigeration system.

CAUTION: The low-pressure piping may be very hot and cause serious burns.

Refrigerant

(8) The A/C system does not function effectively due to an expansion valve malfunction.

Refrigerant

(9) The A/C system does not function due to a defective compressor.
