  Q: How to replace the Air Suspension Compressor on Cadillac DeVille?

  A:

  The replacement process for the Air Suspension Compressor begins with vehicle elevation. Organize a cleaning process for the Air Hose before taking it off from the intake Air Filter and Air Suspension Compressor because you want to stop dirt from getting inside the alc system. Disconnect the air tube from the air dryer before removing the bolt and harness tie with the air tube from the Air Suspension Compressor bracket. Start by taking out the intake Air Filter followed by removing the Air Suspension Compressor's vehicle harness connector and disconnecting 2 bolts and 2 nuts which secure the compressor assembly to the vehicle. Detach the Air Suspension Compressor connector from its anchor point and remove two bolts securing them alongside the heat shield from the bracket then dismount the air dryer from the compressor. Detach the Air Suspension Compressor's Air Hose at two locations and subsequently remove two screws and brackets from the Air Suspension Compressor. To install the 2 brackets on the Air Suspension Compressor use 2 screws but tighten them to 7 nm (62 inch lbs.). The air dryer connects to the Air Suspension Compressor through two mounting points while the installation of the air dryer onto the compressor takes place. Fasten the heat shield to the Air Suspension Compressor bracket through three bolts, setting aside the fourth bolt until the air tube connection is complete, then tighten the bolts to 4 nm (35 inch lbs.). Re-establish the Air Suspension Compressor connector to the connector anchor before you put the Air Suspension Compressor assembly on the vehicle by tightening its 2 bolts with 2 nuts to 9 nm (80 inch lbs.). First, fit the Air Suspension Compressor connector to its matching harness connector then put on the intake Air Filter before installing the air tube to the air dryer. The air tube and harness tie assembly must be joined to the Air Suspension Compressor bracket through a bolt which requires tightening at 4 nm (35 inch lbs.). Driving operations require a brief ignition activation followed by a 45-second wait to ensure sufficient air pressure fills the adjustable Shock Absorbers before lowering the vehicle.
