Refrigerant: Testing and Inspection

ON-VEHICLE INSPECTION 

1. INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET

a. This is a method to specify trouble areas by using a manifold gauge set. Read the manifold gauge pressure when the following conditions are

established.
Test conditions:
-

Engine has been warmed up.

-

All doors are fully open.

-

A/C switch is ON.

-

Engine is running at 1,500 rpm.

-

Air inlet mode selector damper is set at recirculation.

-

Temperature control switch is in MAX. COLD position.

-

Blower speed control switch is in HI position.

-

Air temperature at the air inlet is 30 to 35 degrees C (86 to 95 degrees F).

1. When the refrigerant volume is proper.

Gauge reading:
Low pressure side: 0.15 to 0.25 MPa (1.5 to 2.5 kgf/sq.cm) 
High pressure side: 1.37 to 1.57 MPa (14 to 16 kgf/sq.cm)
