• Q: How to replace the power steering pump (3.1L) on 2005 Buick Century?

  A: Beginning the replacement of the Power Steering Pump (3.1L) demands removal of the coolant recovery reservoir then setting it aside. Remove the accessory Drive Belt first from the Power Steering Pump pulley and then disconnect the ignition control wiring harness situated near the pump. Disconnect both the power steering pressure hose and return hose from the pump followed by removing its mounting bolts to take out the Power Steering Pump. Next you need to disconnect the Power Steering Pump pulley together with its reservoir unit from the pump. Begin with fitting the Power Steering Pump reservoir to the pump before mounting the pulley. Place the pump onto the engine before adding the mounting bolts which should be tightened to 34 nm (25 ft. Lbs.). Reinstall the ignition control wiring harness after finalizing the connection of power steering pressure hose and return hose. Replace the accessory Drive Belt on top of the pump pulley followed by reinstalling the coolant recovery reservoir. Use power steering fluid to fill the power steering system followed by bleeding of the system before checking possible leaks after draining substances from beneath the car.
