Does Power Steering Fluid Go Bad?

power steering fluid reservoir, does power steering fluid go badDoes power steering fluid go bad?  The short answer is yes. Power steering fluid, like any fluid in your vehicle, can go bad in two different ways;

How Does Power Steering Fluid Go Bad?

  1. Contamination
  2. Breakdown

Contamination

Power steering fluid gets contaminated as parts of your system slowly wear out.  Things like bearings, the inside of hoses and gaskets or seals will deposit tiny particles in your fluid.  These particles can be from parts wearing against each other, or just the normal breakdown of the rubber components used in the system over time.  As these particles build up in the fluid it will turn the fluid a darker color so you can tell it is contaminated. As these particles flow around your system with the power steering fluid they can accelerate wear of other components and form clogs in small passages.  If your fluid has become contaminated, perform a power steering fluid flush to renew the fluid and remove the contamination.  When you refill your system, refill your system with BlueDevil Synthetic Power Steering Fluid to keep things working quietly and smoothly.

Breakdown

Besides getting contaminated, power steering fluid can breakdown over time.  Power steering fluid isn’t just oil, it’s a hydraulic fluid with additives to maintain viscosity, prevent foaming, and hold the integrity of the oil.  Over time, these additives can lose their effectiveness and allow foaming or the fluid to get very thin which will accelerate wear in your power steering system requiring you to replace expensive components.  Again, performing a power steering fluid regularly can easily prevent things from happening.

We recommend flushing your power steering fluid every 75,000 miles or 2 years.  You may consider flushing your system more often if you operate your vehicle in severe conditions like temperatures over 100 degrees, stop and go traffic or off-road.

  1. Hi.. My name is Joe Hapokaia and am in Papua New Guinea in the South Pacific. I have read your posts on the Functions and conditions of the Steering Fluids.
    I have here a situation where the Fluid is not flowing to the Steering Box and I have a difficult time turning my landcrusier 79 Series.

    Please advise where i should check or why I have that situation. Your assistance is very much appreciated.

    cheers
    Joe

    1. Joe-

      Thank you for asking about your Toyota Landcruiser. The best place to start would be to flush the power steering unit and re-fill the system with fresh, clean power steering fluid. Make sure the air is bled out of the system to ensure you top the fluid off to the proper level. If the problem persists, it may be an issue with the power steering pump itself.

      Thank you!
