O-Ring Replacement
O-Ring ReplacementImportant
^ Install new GM approved replacement O-rings whenever a joint or fitting is disassembled. Even though and O-ring may look the same, it is extremely important that only recommended service replacement air conditioner O-rings be used or leakage of R-12 may occur.
^ Make sure that the O-ring is the correct size and style, and check that both the O-rings and the fittings are not marred, deformed, or nicked. Damaged line parts can lead to refrigerant leaking.
