  Q: How to service and repair the air suspension compressor on Lincoln Navigator?

  A:

  The air suspension compressor repair process starts with removing the air suspension relay from its bracket while also unattaching the windshield Washer Pump and reservoir. The compressor drier requires disconnecting the air line when you push the orange lock ring inward while pulling the line away from the drier. First disconnect the air compressor electrical connector before removing the air compressor bracket bolts with the goal of taking out the air compressor/drier assembly while tightening these bolts to 9 Nm (80 inch lbs.) during reinstallation. Discard the bracket of the air compressor by taking away the three screws and washers alongside the three rubber isolators. The silencer (Muffler) must be removed by discarding its retaining screws to break the connection with the bracket. Complete insertion of the white air line into its fitting is necessary for a successful reinstallation. The installation should start by reversing the removal steps to guarantee objects remain clear of both the bracket and that the air compressor avoids contact with other components and moves without issue within the rubber isolators and eliminates vibration noises. Check that the bracket remains undeformed so rubber isolators do not load against each other during installation; install only new fasteners when utilizing new brackets from the kit.

  Q: How to Ensure Proper Functioning of the Air Suspension Compressor on a Lincoln Navigator?

  A:

  The first step for repairing or servicing the air suspension compressor demands venting all air pressure from the system to minimize potential injuries. Start the procedure by detaching the inner fender splash shield followed by disconnecting the air line from the compressor drier through lock ring compression and line pull-out. The next step demands removal of the air compressor air intake hose together with the electrical connector. When reassembling the air compressor and bracket assembly replace the three bolts which need to be tightened to 15 Nm (133 lb-in) torque. Make sure to completely insert the white internal part of the air line into its fitting to achieve correct installation. Verify that nothing remains caught beneath or on the bracket while ensuring the air compressor keeps away from surrounding elements to minimize vibration noise and moves easily through all rubber isolators. Verify that bracket deformatiions are absent because such deformations would create forces pushing rubber isolators against each other. The finish installation process requires doing the reverse actions of removal steps.
