Refrigerant: Testing and Inspection
ON-VEHICLE INSPECTION
1. INSPECT REFRIGERANT VOLUME
a. Check the sight glass on the liquid tube sub-assembly A.
Test conditions:
-
Engine is running at 1,500 rpm.
-
Blower speed control switch is at HI.
-
A/C switch is ON.
-
Temperature control switch is at the MAX. COOL position.
-
Doors are fully open.
2. 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:
-
Temperature at the air inlet is 30 to 35 degrees C (86 to 95 degrees F).
-
Engine is running at 1,500 rpm.
-
All doors are fully open.
-
Blower speed control switch is at HI.
-
Temperature control switch is at MAX. COOL.
