How to Change a Power Steering Pump on Cars

by Contributing Writer; Updated June 12, 2017

The power steering pump on a Dodge car supplies pressurized power steering fluid to the steering rack. The pump is mounted in a bracket next to the engine, and is driven by the serpentine belt. Over time the seals and bearings inside the pump may wear out, and cause fluid leakage. If you notice a loss of power assist on your steering wheel, or you hear a loud screeching or squealing noise from the engine bay when you turn the steering wheel, it may be time to replace your power steering pump.

Under The Hood:
