Question 1

How to remove and replace a power steering pump on Volvo V40?

Accepted Answer

To remove the power steering pump, start by firmly applying the handbrake, jacking up the front of the car, and supporting it on axle stands. Next, take out the retaining screws and fasteners to remove the undershield beneath the engine/transmission, followed by the auxiliary drivebelt. Use brake hose clamps to clamp both the supply and return hoses near the power steering fluid reservoir to minimize fluid loss. Clean the area around the power steering pump fluid pipe unions. For engines excluding GDI, loosen the retaining clip and disconnect the fluid supply hose from the pump, unscrew the union nut and retaining clip bolt, and disconnect the outlet pipe while being prepared for fluid spillage; plug the hose/pipe ends and pump unions to prevent fluid loss and dirt entry, discarding the outlet pipe sealing ring for later replacement. Then, through the cut-outs in the pump pulley, loosen and remove the bolts securing the front mounting bracket to the pump, unscrew the bolts securing the mounting bracket to the cylinder block, and remove the bracket. Undo the bolts securing the pump to the rear bracket and maneuver the pump out of position. For GDI engines, unbolt the steering fluid reservoir and set it aside, unbolt the fluid outlet pipe clamps from the car body, disconnect the wiring plug from the pressure switch at the front of the pump, and release the wiring from the retaining clips. Release or cut off the clip securing the low-pressure hose to the top of the pump and remove the hose. Unscrew the fluid outlet pipe union bolt, recover the washer and O-ring, and remove the pipe from the pump while being prepared for fluid loss; plug the pump openings and pipe ends to prevent further fluid loss and dirt entry. Finally, loosen and remove the three pump mounting bolts to take the steering pump from the engine mounting bracket. If the power steering pump is faulty, it must be replaced as it is a sealed unit and cannot be overhauled. For refitting, reverse the removal process, ensuring to fit new O-ring seals and washers where necessary, clean all union fittings, securely reconnect all hoses (using new pipe clips if needed), tighten the pump mounting bolts, refit the auxiliary drivebelt and tension it, and securely hold the undershield with all its retaining screws and fasteners. Upon completion, bleed the hydraulic system.

Question 2

How to remove the Power Steering Pump auxiliary drivebelt on Volvo V70?

Accepted Answer

To remove the auxiliary drivebelt, you first need to improve access to it by removing the cold air inlet duct from the ECU box if it is fitted, and releasing the fluid supply hose from the clip on the pump pulley. To minimize the fluid loss, clamp the fluid supply hose near the pump and then loosen the pressure pipe union lock bracket bolt a few turns and take off the lock bracket. Place absorbent rags underneath the pump, unscrew the pressure pipe union and recover the O-ring. Carefully disconnect the fluid supply hose from the pipe stub on the pump without using excessive force so as not to damage it. Access the pulley and undo the three mounting bolts from the pump and for diesel models to remove the bracket from the back of the pump. If contamination of power steering fluid is suspected, the car should be raised and supported at the front so that the wheels are just off the ground, and then a suitable container should be placed beneath the car to catch the fluid from the hoses while the steering is turned from lock to lock. If a new pump is being fitted, transfer the pulley and reservoir should be done by a dealer or qualified repairer because of the special tools required. For refitting, follow the reverse order of removal while using a new O-ring on the pressure pipe union, tightening the mounting bolts to the specified torque, refitting the auxiliary drivebelt, ensuring pressure pipe union locking bracket fits around the hexagon section of the union and refilling or topping up the fluid reservoir while bleeding the system.
