What is Power Steering Fluid?

First, let’s start with the definition and purpose of power steering fluid.

Power steering fluid is one of the most important hydraulic fluids in your vehicle. It lubricates and cools the power steering system. Additionally, power steering fluid is pressurized, which makes your wheel turn easier.
Most importantly, power steering fluid directly affects steering ease, which in turn impacts driving comfort and safety. A well-maintained power steering system, including regular fluid changes, allows for precise vehicle control and enhances the overall driving experience.

Types of Power Steering Fluid

As with many of the fluids we add to our vehicles, there are many types of power steering fluid. The variety that you use will depend on the make and model of your car. You can find this information in your owner’s manual. Additionally, our team at Ethan’s Honest Automotive can help you determine the right power steering fluid for your vehicle.
But first, you need to know the basic types of power steering fluid.
  • Universal Power Steering Fluid: One of the most convenient types of power steering fluid, universal power steering fluid is compatible with a wide range of vehicles.
  • Automatic Transmission Fluid (ATF): A versatile fluid that serves multiple purposes, including use in some older power steering systems.
  • Synthetic Power Steering Fluid: A power steering fluid formulated using synthetic base oils and advanced additives. It is designed specifically for modern vehicles.
  • Mineral Oil-Based Power Steering Fluid: A rarer type of power steering fluid. Mineral oil-based power steering fluid is made from refined mineral oils and is commonly used in some European and luxury vehicles.
  • Central Hydraulic Fluid (CHF): A specialized fluid used in some advanced power steering systems, particularly in high-performance and luxury vehicles.

Why is Power Steering Fluid Important?

As we have already mentioned, power steering fluid is essential for the smooth driving and user experience of your vehicle. It does the following for our cars.

  • Provides easy steering
  • Lubricating and protecting components
  • Dissipating heat
  • Ensuring performance and safety

How to Check Power Steering Fluid

The best way to ensure your power steering fluid works effectively is to have it regularly inspected by certified mechanics. However, this is not always possible. Use the following steps to perform a basic power steering fluid check at home.

  • Park your vehicle on a flat surface and ensure it is turned off with the parking brake on.
  • Find the power steering reservoir. The location can vary depending on your vehicle’s make and model, but it is typically marked with the words “power steering” or a steering wheel icon.
  • Check the fluid level. Most power steering reservoirs are either translucent or have a dipstick attached to the cap.
  • Inspect the fluid condition: While checking the fluid level, also inspect the color and texture of the liquid.
  • Add fluid or take your vehicle to a professional mechanic.

Signs it is Time to Change Your Power Steering Fluid

Clearly, you want to always keep the right type and amount of power steering fluid in your vehicle. However, not all owners know the signs that their power steering fluid needs to be replaced.

Here are a few signs to look for. If you notice them, bring your vehicle to Ethan’s Honest Automotive or a trusted mechanic as soon as possible.

  • Steering issues: One of the most noticeable signs that your power steering fluid needs changing is difficulty in steering. The steering wheel may be harder to turn, especially at low speeds or when stopped. Erratic steering responses, such as jerkiness, can be a sign of a power steering fluid issue.
  • Whining or groaning noises: If you notice unusual noises from your steering system, that can indicate low or degraded power steering fluid.
  • Discolored fluid: Power steering fluid should be clear, amber, or pink. If you notice that the fluid has turned dark, cloudy, or has particles in it, it’s time for a change.
  • Bubbly fluid: Power steering fluid leaks are often indicated by foaming and bubbles. These indicate that air has gotten into the system, which reduces the power steering’s effectiveness and can lead to increased wear and tear on the power steering pump and other components.
  • Burning smell: If your power steering fluid gets overheated because it no longer properly lubricates the system, it will cause a burning smell. Such a smell is a clear sign that your power steering fluid needs to be changed.
  • Noisy power steering pump: Finally, a noisy power steering pump can be a symptom that the fluid is low or contaminated. The pump relies on the fluid for lubrication and cooling, and without adequate fluid, it can start to make loud whining or grinding noises.

In addition to these signs, if it has been 50,000-100,000 miles since your last power steering fluid change, then it is time to consider having it looked at. Your owner’s manual will include specific information about the recommended maintenance schedule for your vehicle.

Don’t think power steering fluid is unimportant. This crucial vehicle component deserves your attention. Regular maintenance, proper fluid selection, and early detection of issues can prevent costly repairs and ensure your vehicle remains safe and responsive.
