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

  A:

  The air compressor replacement process begins by lifting the vehicle into position while using support equipment. You should turn the ignition on while the engine remains off and implement a scan tool to purge system air pressures for no less than one minute. Before disconnecting the Air Hose from the air compressor please clean all parts while keeping an eye on minimal air pressure remaining in the tubes. Detach the air tube from both the air dryer and electrical connection followed by removing the air inlet and hose from the fuel filler neck bracket. Begin by loosening the mounting nuts then pull the air compressor backwards until it clears the frame slots before complete removal from the vehicle. Place the air compressor inside the vehicle when installing it by using the correct fasteners which must maintain the proper part number alignment. Every fastener requires paint, lubricant or corrosion inhibitor exclusion unless specified because they reduce torque performance along with clamping force. After moving the air compressor forward tighten the mounting nuts to reach 15 nm (11 lb ft) torque to insert the fasteners into the frame slots. Reinstall the air inlet hose to the fuel filler neck bracket followed by connecting the air tube to the air dryer while reconnecting the electrical connection. To activate the air compressor first lower the vehicle and start the ignition while leaving the engine off. Connect a scan tool and run the air compressor for 30 seconds until the rear elevation begins to rise. Cycle the ignition while enabling the engine to function between the off and on positions to permit the air suspension system to reach its desired rear suspension setting.
