  Q: How to Address Issues with the Fan Shroud on a Lincoln Navigator?

  A:

  Start the cooling fan shroud service and repair process by placing the vehicle on a hoist while keeping it in neutral and removing the battery ground cable. Start by draining the engine cooling system and remove the upper Air Deflector through removing both the 12 pushpin retainers and the deflector unit. Service technicians should disconnect the outlet pipe of the air cleaner (ACL) by removing its nut and electrical cables that require tightening to 10 Nm or 89 lb-in before reinstallation. Afterward they should remove the wiring harness retainer. First, disconnect the upper Radiator hose from the radiator and the position retainer of the cooling fan shroud. Next, execute the removal of the electrical connector and wiring harness position retainer. The procedure requires disconnection of vacuum components that include the wiring harness position retainer from the vacuum reservoir and vacuum connectors with an electrical connector from the LH side of the cooling fan shroud. Once these steps are completed you can remove the vacuum canister. Reviewing the torque to 7 Nm or 62 lb-in before reinstalling, remove the 2 cooling fan shroud bolts and wiring harness retainers along with the wiring harness retainer from the RH side of the radiator. Users must first remove the mass air flow (MAF) sensor electrical harness position retainer followed by the power steering fluid hose position retainer from the Radiator Support and the bolt which will allow space for relocating the Power Steering Reservoir (reinstalling each component with 11 Nm or 97 lb-in torque). The radiator overflow hose should be disconnected while the 2 lower cooling fan shroud pushpin retainers are removed along with the downward release of a lower position tab. The shroud can then be lifted upwards for locking into new placement. You should remove the clip followed by disconnecting the lower radiator hose quick connector from the radiator and finally take out the cooling fan shroud. You should follow the removal steps in reverse order to install the 2 new lower cooling fan shroud pushpin retainers.

  Q: How to service and repair the cooling fan shroud on Lincoln Navigator?

  A:

  Service and repair of the cooling fan shroud begins with placing the vehicle on a hoist where the neutral gear engages. First disconnect the battery ground cable then drain all fluid from the engine cooling system. Perform this service by removing the air cleaner outlet pipe then loosen the nut while disconnecting electrical cables that must be tightened to 10 Nm (89 inch lbs.) during reinstallation. Start the cooling fan shroud service by unplugging the wiring harness retainer before removing the upper Radiator hose from the radiator followed by disconnecting the upper radiator hose position retainer from the cooling fan shroud. The electrical connector must be disconnected together with the wiring harness position retainer before vacuum reservoir removal. Additionally, vacuum connectors and electrical connector disconnection from the cooling fan shroud's LH side is required. You must first disconnect the wiring harness retainer on the radiator right-hand side before removing two cooling fan shroud bolts and wiring harness retainers while tightening each to 10 Nm (89 inch lbs.) for reinstallation. Start the four bolts of the power distribution box (PDB) support bracket manually before setting aside the PDB and its bracket. Take caution to protect the radiator support when starting the bolts and tighten all PDB support bracket bolts to a torque value of 10 Nm (89 inch lbs.) upon reinstallation. Detach the Mass Air Flow Sensor position retainer and the power steering fluid hose position retainers which connect to the radiator support and cooling shroud. The Power Steering Reservoir can be positioned aside utilizing this bolt while securing it to 11 Nm (8 ft. lbs.) when reassembly is complete. Remove the degas bottle coolant inlet hose from the radiator before you unlock the lower cooling fan shroud position tab and raise the lower shroud until its lower tab locks in position. Drain the clip before you disconnect the lower radiator hose quick connect coupling from the radiator and detach the cooling fan shroud. The reverse procedure should be followed for reinstallation.
