Does Power Steering Fluid Need to Be Replaced?


Power steering fluid is essential to your vehicle's power steering system. It helps lubricate and cool the components, allowing for smooth operation and preventing wear and tear. The question is: does it need to be replaced? Let's take a look at what you should know about power steering fluid to make an informed decision.

The Basics

Power steering fluid is hydraulic oil that circulates through the engine's power steering pump, hoses, and cylinders to assist with turning the wheels while driving. It also helps reduce slippage between moving parts, known as frictional losses.
This reduces the amount of effort required by the driver when turning the wheel. If the fluid is old, contaminated, or low in level, it could lead to reduced effectiveness of the power steering system.

When to Replace It

Power steering fluid should be replaced regularly – typically every two years 50, 000 miles. More frequent replacements may be necessary if you drive your car frequently or under harsher conditions (e.g., off-roading). Here are some other factors that can affect when you should replace the fluid:

  • Age of vehicle
  • Quality of oil
  • Driving habits
  • Environmental conditions
  • Leaks

It's dangerous to ignore the regularly scheduled power steering fluid maintenance. If left unchecked, it can lead to severe problems such as stiff steering, grinding noises when turning the wheel, and in some cases, even a complete failure of the power steering system.

Signs You Need to Replace It

There are several signs that you should replace your power steering fluid. These include:

  • Dark or discolored fluid
  • Sluggishness when turning the wheel
  • Whining noises during operation
  • Low fluid levels in the reservoir

If you notice any of these signs, it's essential to replace your power steering fluid as soon as possible.
