Discharging A/C System

NOTE: Recent findings by the EPA indicate that refrigerant is harmful to the Earth's protective Ozone layer. When discharging refrigerant, avoid allowing refrigerant to enter the atmosphere. Refrigerant recovery/recycle system should be used whenever possible instead of discharging system. Many states now require by law the use of recovery/recycle systems. Check local laws before proceeding.

General Motors does not provide procedures for discharging of A/C system. To discharge system, follow procedures for refrigerant recovery using a recovery/recycle system as outlined under REFRIGERANT RECOVERY in this article.
