Pressure Relief Valve

WARNING: This page does not describe the selected car, but rather 38 other vehicles, including the 1987 Pontiac Sunbird, 1987 Pontiac Safari, 1987 Pontiac Grand Prix, 1987 Pontiac Grand Am, and 1987 Pontiac Firebird. However, it is still accessible from the selected car via links, so may be relevant.

Pressure relief valve is located on the rear of the compressor. It opens automatically when the discharge side pressure reaches approximately 440 psi. This prevents damage due to excessive pressure.
