Placing System In Operation

WARNING: This page does not describe the selected car, but rather 60 other vehicles, including the 1995 Pontiac Trans Sport, 1995 Pontiac Sunfire, 1995 Pontiac Grand Prix, 1995 Pontiac Grand Am, and 1995 Pontiac Firebird. However, it is still accessible from the selected car via links, so may be relevant.

After component service or replacement has been completed, evacuate system thoroughly with a vacuum pump. Charge system with proper amount of refrigerant. See the REFRIGERANT OIL SPECIFICATIONS tables in the A/C COMPRESSOR SERVICING article. Perform leak test. After system has been leak tested, check system operation.

NOTE: A/C systems normally will not need additional refrigerant oil unless oil loss has occurred due to ruptured lines, leaking compressor seals, compressor overhaul or component replacement.
