Power Steering Pump Reservoir

The power steering fluid replacement within the vehicle starts with draining the power steering fluid from the pump before proceeding with the Power Steering Reservoir removal. You must first remove the pump mounting studs before completing the separation of the connector and fitting assembly together with its o-ring seal. You must remove the control valve assembly with the flow control spring from the pump housing assembly if needed. First remove the Power Steering Reservoir assembly from the pump housing assembly then extract the o-ring seals including parts 1, 4, and 5 along with the magnet before cleaning the magnet. Power Steering Pump replacement becomes necessary when the welch plug inside Power Steering Pump housing appears deformed or dislodged. To assemble the parts use new o-ring seals that require lubrication with power steering fluid applied to (1, 4 and 5). The pump housing assembly accepts first the control valve assembly and flow control spring and then the o-ring seals (1, 4, and 5) before accepting the magnet. The pump housing assembly must receive the Power Steering Reservoir assembly along with an installed o-ring seal before connecting the connector and fitting assembly to this unit. Install pump mounting studs to the pump housing until they reach 58 n.m (43 lb ft) torque whereas connector and fitting assembly requires 75 n.m (55 lb ft) torque for mounting.

The power steering fluid drainage from the Power Steering Pump must occur as the first step for Power Steering Reservoir replacement. After removing the mounting studs secure the pump you can disconnect the fitting assembly and o-ring seal maintained within the fitting. The assembly requires removal of the control valve and the flow control spring from the pump housing when needed. Start by removing the o-ring seals , and from the reservoir assembly when separating it from the pump housing assembly . The cleaning process should include the magnet . Failure to have the Power Steering Pump housing welch plug installed in proper form requires immediate replacement of the pump unit. The assembly process requires new o-ring seals to which power steering fluid provides lubrication. The assembly of control valve components and flow control spring in the pump housing should be performed before adding o-ring seals numbered 1, 4 and 5. Connect the magnet to the pump housing assembly before inserting the reservoir assembly to it while you install the o-ring seal. After that attach the pump housing assembly with the connector and fitting assembly. Use the pump mounting studs to secure the pump housing while applying torque up to 58 nm (43 ft. Lbs.). After that, torque the connector and fitting assembly to a final torque of 75 nm (55 ft. Lbs.).

Siphoning all power steering fluid from the reservoir should be your first step when you plan to replace the power steering reservoir. Begin by disconnecting both the outlet hose from the reservoir and then removing the inlet hose. Use tools to remove mounting nuts on the power steering pump remote reservoir while separating it from its position. Installation of the power steering pump remote reservoir necessitates proper fastener caution when attaching it to the vehicle. Fasten the power steering pump remote reservoir mounting nuts with a torque of 11 Nm (97 lb in). You should add the reservoir inlet hose to the reservoir followed by attaching the reservoir outlet hose to the reservoir. The power steering system needs a bleeding procedure as its final step.

The first step to replace the Power Steering Reservoir off the vehicle entails draining the power steering fluid from the Power Steering Pump. First unfasten the pump mounting studs then detach the connector and fitting assembly before taking out the o-ring seal from the connector and fitting assembly . You should remove the control valve assembly with the flow control spring if needed from the pump housing assembly. Thereafter disconnect the reservoir assembly from the pump housing assembly while taking out the o-ring seals , and and the magnet for cleaning. Examine the welch plug within the Power Steering Pump housing using the original position; disassemble the pump if either the plug is misshapen or out of its proper location. Implementation of assembly begins with power steering fluid-lubricated new o-ring seals followed by control valve assembly and flow control spring installation onto the pump housing assembly then the sequential installation of o-ring seals (1, 4 and 5). The pump housing assembly needs the magnet installed followed by connecting the reservoir assembly to the pump housing assembly. You should install the o-ring seal and the connector and fitting assembly to the pump housing. Installing mounting studs onto the pump housing should be tight to 58 nm (43 ft. Lbs.) before making 75 nm (55 ft. Lbs.) final torque on the connector and fitting assembly .

The first step to replace the remote power steering reservoir involves removing the power steering fluid through siphoning procedures from the reservoir. Start by disconnecting both the reservoir outlet hose from the reservoir then removing the reservoir inlet hose. The first step requires removal of the power steering pump remote reservoir mounting nuts before taking out the power steering pump remote reservoir itself. Complete installation of the power steering pump remote reservoir requires securing it to the vehicle while tightening mounting nuts to 7 Nm (58 inch lbs.). Connect the reservoir inlet hose to its opening and join the reservoir outlet hose to the same hole. Power steering system bleeding must be performed as the final step.

Take off the power steering pump remote reservoir mounting nuts and remove the power steering pump remote reservoir.
