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.
