Liquid Leak Detection/Pressure Testing Methods

Due to their lack of sensitivity and restricted visibility in today's refrigerant systems, liquid/bubble leak detectors have very limited usefulness. Therefore, the liquid leak detection/pressure testing methods are not recommended for this vehicle.

SERVICE PORT SEAL/CAP
The primary seal for the service ports is the sealing cap. The cap contains a specially designed O-Ring or gasket which provides a leak free seal. Should the cap be loose, missing, or the wrong usage, a loss of refrigerant could result.
