    Q:
    How to remove the Power Steering Pump on Chevrolet Blazer? Posted by Keyvan T.
    A:
    To remove the power steering pump, start by disconnecting the cable from the negative terminal of the battery. Then, remove the upper fan shroud and the serpentine drive belt. Use a special power steering pump pulley remover to remove the pulley from the pump. Place a drain pan under the pump and disconnect the pressure and return hoses, plugging them to prevent contaminants from entering. Remove the pump mounting fasteners and lift the pump from the vehicle, being careful not to spill fluid on painted surfaces. To install the new pump, position it in the mounting bracket and secure it with bolts and nuts. Connect the hoses and tighten the fittings securely. Use a special pulley installer tool or a fabricated alternative tool to press the pulley onto the shaft. Install the drive belt and fill the power steering reservoir with the recommended fluid. Finally, bleed the system to ensure proper functioning.
