Power Steering Pressure Hose

Service and repair operations on the power steering line and hose should start once the vehicle is positioned on a hoist in NEUTRAL gear. Before beginning work the fire suppression system needs to be de-powered to protect workers from serious injuries. The removal process requires the steering line clamp plate bolt and pressure and return line detachment from the steering gear using new O-ring seals that must be installed before tightening to 17 Nm (150 lb-in). New O-ring seals need to go into the connections to avert leakages and their tightening procedure should be set to 17 Nm (150 lb-in). For installation of the pressure line bracket-to-engine nut use a torque of 8 Nm (71 lb-in) after placement. Detach the inlet connection of the Power Steering Pressure (PSP) switch electrical connector together with the pressure line-to-pump fitting and discard the Teflon® seal. Use a new Teflon® seal for installation and secure the fitting with 73 Nm torque at 54 lb-ft. The power steering system requires filling after performing the installation. The vehicle needs a newly powered system after both safety procedures to prevent injuries are completed if it contains a fire suppression system.

The repair process for power steering line and hose begins when you position the vehicle in NEUTRAL position on a hoist for service. Protection from foreign materials entering the power steering system is essential because it creates complications that lead to component breakdowns. The power steering gear requires users to remove its clamp plate bolt followed by disconnecting both pressure lines and return lines. Users must discard their O-ring seals. Follow the installation procedure by using 17 Nm torque setting while tightening all connections at 150 lb-in. After separating them, install the pressure line bracket-to-engine nut and tighten it to 8 Nm (71 lb-in) when reinstalling it. Disconnect the electric connector of the Power Steering Pressure (PSP) switch and then separate the pressure line-to-pump fitting by discarding the Teflon(R) seal. New Teflon(R) seals need replacement during reinstallation and the fitting requires a torque value of 73 Nm (54 lb-ft). You should employ the Teflon(R) Seal Installer Set to mount a new seal onto the pressure line-to-pump fitting. To finish the service you need to execute the power steering system fill operation.

Any Teflon O-ring seals remaining in the gear ports of the steering gear are also removed.
