Refrigerant: Testing and Inspection
HEATING / AIR CONDITIONING: REFRIGERANT: ON-VEHICLE INSPECTION
1. INSPECT REFRIGERANT VOLUME
(a) Check the sight glass on the liquid tube sub-assembly.
(1) Prepare the vehicle according to the chart below.
(2) Compare the sight glass to the following chart.
*: Bubbles in the sight glass with the vehicle's interior temperature above 35°C (95°F) can be considered normal if cooling is sufficient.
2. INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET
HINT
This is a method where a manifold gauge set is used to help locate the problem.
(a) Read the manifold gauge pressure when the following conditions are met:
Test conditions:
Temperature at the air inlet with the switch set at RECIRC is 30 to 35°C (86 to 95°F).
The engine is running at 1500 rpm.
The blower speed control switch position is at "HI".
The temperature control dial position is at "COOL".
