It removes contaminants from the steering fluid to protect the pump and gear, preventing wear and steering issues. Replace this filter during regular power steering fluid service or when experiencing noisy or stiff steering, as a clogged filter can reduce fluid flow and cause system damage. The cellulose media offers 25-micron filtration with a bypass valve that opens at 15-16 psi to maintain flow if the element becomes plugged.
