The power steering pump produces high pressure between 800–2000 pounds, with high heat, leading to fluid breakdown and failure.
Symptoms include groaning and whining noises, erratic steering and pump leaks.
A powerful cleaner suspends and dissolves varnish and gums in the power steering system and then all of the old fluid is replaced with new high-tech power steering fluid for both conventional sector and rack and pinion. The benefit will be a quieter-operating, longer lasting power-steering system.
