A power steering pump is a mechanical device that assists in the steering of a vehicle by providing hydraulic power to the steering system. It is typically driven by the engine’s crankshaft via a serpentine belt and consists of a pump, a reservoir, and various hoses and fittings. The pump draws hydraulic fluid from the reservoir and pressurizes it, which is then directed to the steering rack or steering gear to assist in turning the wheels.
A faulty power steering pump can lead to a variety of issues, including difficulty steering, increased steering effort, and abnormal noises. Replacing a power steering pump is a relatively complex task that requires specialized tools and knowledge, but it can be completed in a few hours by following the correct steps.
