Your power steering is your best friend when driving around town. The power steering pump is what generates the fluid pressure that assists your steering inputs. The pump is run off a belt from the drive pulley and due to the constant usage, they are known to suffer from faults. 

What is a power steering pump?

The power steering pump works much the same as any other pump. The drive pulley spins the rotor shaft inside the pump. This creates a vacuum that pulls power steering fluid from the reservoir and forces it through a smaller diameter hose. This high pressure fluid is then sent through the system and back to the reservoir. The pump will always run when the engine is running and if any contaminants get into the system it can lead to damage.

The mechanic will drain the power steering fluid from the system and remove coverings in the way of the pump itself. They will then get the tension out of the drive belt and take the belt off the pump. The pump will then be disconnected from the feed lines, return lines and any wiring or connectors. The pump can then be disconnected from its mounts and the new power steering pump fitted in its place. The hoses, wiring and belts will be reconnected and the power steering fluid refilled. The system will be test run to make sure everything is working properly.
