The average vehicle on the road today weighs about 4,000 pounds. That’s two tons! Cars today weigh much more than their classic counterparts for two main reasons – more efficient engines and cabin comfort. To wheel such a beast is no easy task. Early cars were so hard to drive that when power steering first came out, it was almost overpowered – some companies advertised cars that could be steered with only a pinky finger. Today, we know how to balance power steering properly – not too much but not too little. Achieving such a balance requires a very accurate positioning and maintenance of the power steering system. One of the most important parts, the lifeblood, of most modern power steering is called power steering fluid.
What is power steering fluid?
Power steering fluid is essentially what makes power steering possible. When you steer, power steering fluid applies pressure to a system called the rack-and-pinion. For example, if you steer to the left, fluid is used to apply pressure to the left side of a piston, mounted to the rack. Think of it as a crane helping you lift something no human has the strength to lift – you are the brain, the input, the control center – the fluid is the brawn, the workhorse, the crane.
Why do cars need their fluid flushed?
Power steering fluid, much like oil, will get dirty over time. Deteriorating rubber, bits and pieces of dirt and grime, and a slew of other things can get into the fluid. When the fluid has debris in it, it is harder to be pushed around to help you steer – causing premature wear.
When should I get my power steering fluid flushed?
This is usually a case-to-case event. Some cars actually give out a certain milage when it should be replaced in the owner’s manual, while some cars do not. The most obvious of signs include having a harder time steering the car or if when you turn the steering wheel you hear noises.
