Power Steering Fluid
Power Steering Fluid
Pumped from a high pressure pump attached to the engine, power steering fluid under pressure assists in turning at lower speeds.
Service Interval: Undetermined, 45k-60k perhaps
Most vehicles like Lexus never list this as a maintenance item whatsoever, aside from checking the fluid level. Aside from a very dirty appearance, it is difficult to evaluate this fluid by looks or feel.
Why do we replace/service:
Power steering fluid typically has a high amount of detergent and is generally similar or may even be transmission fluid in Lexus vehicles. These detergents wear out and the fluid breaks down over time.
What happens if we don’t service:
Over time, fluid break down can cause premature wear on the power steering components.
General Recommendations:
Many vehicles never call for anything more than a simple fluid level check. Performing a fluid replacement every 45-60k miles may be good insurance against failure of these components.
