  Q: What steps should be taken before servicing the air suspension compressor on Mercury Marauder?

  A:

  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.

  Q: What precautions should be taken before servicing the air suspension compressor on Mercury Grand Marquis?

  A:

  To protect against sudden air spring changes that could harm people, the first step before compressor servicing is ensuring power to air suspension power is disabled. The air suspension service must be set to off position. Position the vehicle into neutral and maintain it on the hoist. Start the process by removing the air cleaner followed by removal of the air compressor drier cover using a pushpin first and a cover second protocol. Finish the task by pulling out the canister through its pushpin removal. Disconnect the air suspension compressor by using the quick connect locking ring compression to extract the air tube before separating the electric connector. Reassemble the air suspension compressor brackets by tightening their bracket nuts to 5 Nm (44 lb-in) torque setting. The installation ends with removing the air suspension compressor assembly. The installation requires feeding at least 3 mm (1/8 in) of visible white tube into the fittings where air tubes connect to the compressor drier before proceeding with installation.
