Stabilizing A/C System

WARNING: This page does not describe the selected car, but rather 110 other vehicles, including the 1999 Saturn SW2, 1999 Saturn SW1, 1999 Saturn SL2, 1999 Saturn SL1, and 1999 Saturn SL. However, it is still accessible from the selected car via links, so may be relevant.
  1. Once manifold gauge set is attached to system and test hoses have been purged, the system is ready for testing. Place all test hoses, gauge set and other equipment away from all moving parts of engine.
  2. Start engine, and turn A/C controls to maximum cooling position (full cold or MAX A/C). Set blower on high speed. Open doors and/or windows. Operate system for 5-10 minutes. System should now be stabilized and ready for test readings.
