  Q: How to remove and install a power steering pump on Lincoln Navigator?

  A:

  The process of power steering pump removal starts by taking away the fan and shroud followed by the Drive Belt. First detach the three bolts before setting the power steering pump reservoir in a safe position. First disconnect and drain the power steering pump supply line through its reservoir pump hose. Then disconnect the power steering pressure hose for draining the power steering system. Untighten the nuts followed by the deflector then disconnect the two bolts. A safe operation environment is achieved by shutting off the electrical power to air suspension through the air suspension switch located in the right-hand kick panel area before the start of operations. Lift the vehicle before taking out bolts that secure the skid plate when present. The Electronic Variable Orifice (EVO) power steering control valve actuator requires its electrical connector to be disconnected first before removing the bolt. Owners can then lower the vehicle. The power steering pump should be removed together with the Power Steering Reservoir pump hose and the power steering pressure hose. The Power Steering Pump Remover tool enables the removal of the power steering pump pulley from a vise-clamped pump before you retrieve the pump from the vise. To put the steering pump back in service replace its pulley when it reaches two installation cycles and check the hub vicinity around the web for paint marks; replace the pulley if it shows two paint marks or apply a paint pencil marker otherwise. Install the power steering pump pulley to the power steering pump using the Power Steering Pump Pulley Replacer after you position it within a vise. Follow this by removing the pump from the vise. Installation of a new seal at the power steering pressure hose pump end requires the disposal of the old seal followed by stretching the new seal onto the Seal Replacer until it covers the tube nut properly. Begin by attaching the power steering pressure hose to the power steering reservoir pump hose followed by setting the power steering pump into the vehicle and implementing loose hardware fastening of its two bolts. Lift and holding the vehicle again add the bolt then connect the EVO power steering control valve actuator electrical connector at its destination. The skid plate can be installed by first positioning it and then installing its bolts. Next proceed to lower the vehicle while you begin tightening the two bolts followed by installing belt deflector pieces then nuts before connecting the power steering pressure hose and power steering reservoir pump hose. Attach the power steering oil reservoir by installing its three bolts. Install the drive belt alongside the fan and shroud and finish the power steering system procedure by filling then bleeding while searching for any potential leaks.

  Q: How to service and repair the power steering pump on Lincoln Navigator?

  A:

  The power steering pump service requires users to remove its pulley before proceeding. The extract of power steering fluid requires a proper suction device to work from the reservoir. Unclamp and then disconnect the power steering fluid reservoir-to-pump supply hose before unscrewing the power steering pressure line bracket-to-engine nut when placing it back ensure proper torque is 40 Nm (30 lb-ft). After taking off the power steering pressure line from its fitting you should dispose of the old Teflon(R) seal while tightening the new fitting to 65 Nm (48 lb-ft) torque settings during engine assembly. The power steering pump has three securing bolts which must be removed before tightening them to 25 Nm (18 lb-ft) torque during reinstallation. The reinstall process starts with using the Teflon(R) Seal Installer Set to place a fresh Teflon(R) seal on the pressure line-to-pump fitting followed by filling the power steering system.
