Refrigerant: Testing and Inspection
Refrigerant Leak Check
INSPECTION
1. Operate the A/C system for approx. 10 minutes, and confirm that the high-side pressure shows at least 690 kPa (7.03 kg/sq.cm, 100 psi). Then
stop the engine to start the leak test.
2. Starting from the connection between the high-pressure tube and evaporator, check the system for leaks along the high-pressure side through the
compressor. The following items must be checked thoroughly.
-
Connection between the tube and tube fitting
-
Connection between 2 parts
-
Connection between the tube and nut
3. Check the joint and seam between the pressure switch (dual switch) and receiver dryer.
4. Check the connections between the condenser and tubes, and welded joints on the condenser. The leak tester may detect the oil on the condenser
fins as a leak.
5. Check the joint between the compressor and hoses.
6. Check the machined area of compressor and other joints on the compressor.
7. Check the thermal limiter (if equipped) on the compressor housing.
8. Check the compressor shaft seal at the area near the center of compressor clutch pulley. Some shaft seals show a slight amount of leakage about 28
g (1.0 oz) per year. This is not a problem.
9. Starting from the connection between the low-pressure tube and evaporator, check the system for leakage along the high-pressure side through the
compressor. The following items must be checked thoroughly.
-
Connection between the tube and tube fitting
-
Connection between 2 parts
