3. Move probe along component approximately 25 - 50 mm (1 - 2 in)/sec.
CHECKING PROCEDURE
To prevent inaccurate or false readings, make sure there is no refrigerant vapor, shop chemicals or 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 °C (61 °F). If less than specification, recover/evacuate
and recharge the system with the specified amount of refrigerant. Refer to "HFC-134a (R-134a) Service Procedure".
NOTE: At temperatures below 16 °C (61 °F), leaks may not be detected since the system may not reach 345 kPa (3.52 kg/sq.cm, 50 psi).
