Power Steering Pump

Place a drain pan beneath the pump before removing the hoses while keeping them capped for preservation. Professionally install the Power Steering Pump pulley remover (J 25034-C) by making sure the pilot bolt reaches the bottom of the pump shaft through a process of directing the nut to the pilot bolt top position before holding the bolt and counterclockwise nut rotation. Proceed to take out the pump by disconnecting the front mounting bolts then removing rear mounting nuts from the studs along with the evo actuator electrical connector. To install the pump first use Power Steering Pump pulley installer (J 25033-C) then secure front mounting bolts with 50 nm (37 ft. Lbs.) torque followed by rear mounting nuts tightened to the same value of 50 nm (37 ft. Lbs.). The pump shaft should receive the pulley while using j 25033-c to add it through the pilot bolt until it rests within the pump shaft. Keep holding the pilot bolt and turn the nut clockwise. Position the pulley at the Power Steering Pump shaft end where it shows 0.5 mm (0.020 inch) of slippage. After installing the Drive Belt and hoses and electrical connector to the evo actuator complete the system fill and bleeding operation and check the hoses and wiring clearance.

Use the Power Steering Pump Pulley Remover (J 25034-C), ensuring the pilot bolt bottoms in the pump shaft by turning the nut to the top of the pilot bolt, holding the pilot bolt, and turning the nut counterclockwise.
