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)
