set properly per the manufacturer's operating instructions.
The leak detector is a delicate device. In order to use the leak detector properly, read the manufacturer's operating instructions and perform any specified 
maintenance.

1. Position the leak detector probe approximately 5 mm (3/16 in) away from the point to be checked.

2. When testing, circle each fitting completely with the leak detector probe.

3. Move the leak detector probe along the component at approximately 25 to 50 mm (1 to 2 in)/sec.

CHECKING PROCEDURE

NOTE:  To prevent inaccurate or false readings, make sure there is no refrigerant vapor, shop chemicals, or cigarette smoke in the vicinity of the
vehicle. Perform the leak test in a calm area (low air/wind movement) so that the leaking refrigerant is not dispersed.

1. Turn engine OFF.
2. Connect a suitable A/C manifold gauge set to the A/C service ports.
3. Check if the A/C refrigerant pressure is at least 345 kPa (3.52 kg/sq.cm, 50 psi) above 16 degrees C (61 degrees F). If less than specification,

recover/evacuate and recharge the system with the specified amount of refrigerant.

NOTE:  At temperatures below 16 degrees C (61 degrees F), leaks may not be detected since the system may not reach 345 kPa (3.52 kg/sq.cm,
50 psi)
 pressure.

4. Conduct the leak test from the high side (compressor discharge to evaporator inlet) to the low side (evaporator drain hose to the compressor shaft

seal). Refer to MTC-90, "Components".  See: Diagrams/Exploded Views/Heating and Air Conditioning/Manual Air Conditioner Clean the
component to be checked and move the leak detector probe completely around the connection/component.

Perform a leak check for the following areas:
