Chevrolet Power Steering Pump Pulley

Power Steering Pump Pulley And Belt Drive

A power steering pump pulley transfers rotation from the accessory drive belt to the hydraulic steering pump. The pulley, belt and pump work together; the pulley does not create steering pressure on its own.

A-Premium offers pulleys for selected applications with different diameters and groove counts. Match the engine, belt type, pump shaft and mounting design to the vehicle before choosing a replacement.

Pulley Alignment And Belt Noise

Pulley offset matters because the belt must track in line with the other accessory pulleys. A pulley with the right number of grooves can still be wrong for the shaft or belt path. Check the mounting style and installed alignment specified for the pump.

A squeal or chirp may come from the belt, tensioner, another pulley or an alignment problem. Inspect the drive system before assuming the steering pulley alone is damaged. If the pump itself is leaking or failing, a power steering pump is a separate repair part.

Power Steering Pulley Replacement

Pulley attachment depends on the pump design. Some pulleys are pressed onto a shaft and need the correct puller and installation tool; others use a different connection. Follow the vehicle and pump instructions for removal, seating and alignment rather than using a universal hammer-on method.

Inspect the shaft and belt condition while the drive is apart. A replacement pulley does not correct a seized pump, damaged belt or unrelated fluid leak.
