Leak Testing - Refrigeration System

CAUTION: Do not operate the detector in a combustible atmosphere since its sensor operates at high temperatures or personal injury and/or damage to the equipment may result.

Perform a refrigerant leak test on the system whenever you suspect a leak. Also perform a refrigerant leak test after a service operation which disturbs any of the following items:
- The components
- The lines
- The connections

Ensure that the vehicle has at least 0.45 kg (1 lb) of refrigerant in the A/C refrigeration system in order to perform a leak test.

Refer to Refrigerant Recovery and Recharging for recharging the A/C system.
