Compressor

The service process for air suspension compressors needs a shutdown of electrical power to the air suspension system to avoid arbitrary air spring pressure changes that might shift the vehicle during lifting or jacking or towing. First switch off the air suspension control before removing the engine air cleaner and air compressor drier cover by taking out their pushpins. You should first take out the snorkel by removing its pushpin. Start by unhooking the air compressor through two processes of first interfacing the locking ring to compress the quick connect then pulling out the air line afterward disconnecting its electrical connection. You should first support the vehicle while raising it then unscrew all nuts before lowering it down for air compressor extraction. Install the air lines into the compressor drier with a minimum white air line presence of 3 mm (1/8 inch) visible from the fittings. The installation should finish by following the opposite procedure of removal.

Service and repair of the air suspension compressor requires disconnecting power from the air suspension system first to stop unexpected air spring changes that may result in vehicle shifting while you work. Start by shutting down the air suspension switch followed by removing engine air cleaner and air compressor drier cover through pushpin removal. Prototype next requires removal of both the pushpin securing the snorkel and complete removal of the snorkel. To disconnect the air compressor workers must first compress the quick connect locking ring then draw out the air line before ending by separating the electrical connector. The vehicle needs support for maintenance and workers must remove the nuts after vehicle lowering to extract the air compressor. The installation of air lines into the compressor drier requires at least 3 mm (1/8 in) of visible white air line exposure at the fitting end. Beginning from the opposite direction as removal allows the completion of the process.
