Best Power Steering Fluid Buying Guide & FAQ

There are a number of factors that go into deciding which is the best power steering fluid for your car. The type of power steering unit you have, the make and model of your vehicle, and your main purposing in purchasing the fluid, all have a role to play. Buying the wrong power steering fluid can have negative consequences for your power steering pump and your vehicle’s performance. To help you make the right decision, this part of the buying guide takes a closer look at power steering fluid, why it should be replaced, and how it should be used. It also answers some of the most frequently asked questions about power steering fluid.

What is Power Steering Fluid?

Power steering fluid is an essential element in ensuring your vehicle’s power steering works effectively. The fluid helps to keep the system lubricated, provides balance, and helps to transmit pressure to where it is needed. Power steering fluid is a form of hydraulic fluid that is usually either silicone or mineral oil based. Others power steering fluids are made from synthetic base oil and these are automatic transmission fluids. These different types are suitable for different types of power steering systems and using the wrong one could damage your power steering pump.

Power steering helps you to steer your vehicle more easily and with less effort. It does this through the use of electric or hydraulic actuators that provide controlled energy to the steering mechanism. This reduces the amount of physical effort needed to turn the vehicle’s wheels when it is moving slowly or standing still.

Where the power steering works on hydraulic power the system works through an actuator. This is a hydraulic cylinder that is part of the servo system. In these systems, there is a direct mechanical connection between the steering wheel and the linkage that steers the vehicle’s wheels. If the power steering fails, then the vehicle can still be steered manually.

Electric power steering instead uses an electric motor as the actuator. Power to the motor is controlled by the rest of the power steering system. Sensors are used to detect the steering column position and torque. These reading are sent to the computer module, which in turn applies assistance via the steering column or the motor.

Why You Should Replace Power Steering Fluid?

Replacing your fluid is an essential part of vehicle maintenance. Failing to replace your power steering fluid at the right time can lead to a host of problems, including the total failure of your power steering pump or system. One of the difficulties with power steering fluid is knowing when to change it. Changing intervals differ between vehicles, so if you are unsure you should check your vehicle’s manual or contact your dealer for advice.

However, there are some sure signs that it is time to change your power steering fluid. You should check the fluid at regular intervals and if you notice a change in color, then the fluid is getting close to needing changing. As with most oils and fluids in your car, the darker the fluid, the more likely it is that it needs changing. If you notice a burning smell while checking your fluid levels, this is a sign that it is heat damaged and needs replacing. Similarly, if you notice debris or particles in the fluid, then it needs changing. These particles can be a sign that your seals are degrading, which can cause leaks in the power steering system. If these particles make their way into the power steering system, then the damage they cause could be catastrophic.

Other signs that your power steering fluid needs changing include noises coming from the pump that controls the movement of the fluid in your power steering system. As impurities in the fluid built, they make it more difficult for the pump to work efficiently. As this happens, you may also notice that it takes more effort to turn your vehicle at low speeds or that the steering wheel tugs against you as you try to turn.

How to Use Power Steering Fluid?

Most power steering fluids are ready to use. If there is nothing wrong with the fluid in your reservoir and no leaks in the seals, then simply add fluid to the reservoir slowly, checking the levels as you pour. Remember the fluid expands as it heats up, so it is important not to overfill the reservoir.

If there are issues with the fluid such as signs of corrosion or seal degradation, you may need to flush the system, deal with any issues, and completely replace the power steering fluid. Some fluids include a power steering leak fix that revitalizes seals as well as supporting your power steering. If you are unsure whether a fluid is suitable and before you attempt to flush your system check with your vehicle’s manual or use a trusted mechanic.

Best Power Steering Fluid FAQ:

Q: How do I check power steering fluid level?

Checking your power steering fluid level is straightforward, but if you are unsure, always refer to your vehicle’s manual. The first step is locating your power steering fluid reservoir cylinder. It is usually located close to the power steering pump. In some vehicles it is located with the pump hoses, however, in either case, it should be made of either metal or plastic and have a clearly labeled cap. Once you have located the cylinder there are two ways to check the level of the fluid. Some cylinders are translucent, meaning you can see through the material and check the fluid level against the minimum and maximum levels that are indicated on the cylinder itself. Remember that you will still need to open the cylinder to check the color and smell of the fluid, and to check for debris. Where you cannot see through the cylinder, you will need to use a dip stick. Most vehicles have a dip stick attached to the underside of the cap to make this process easier. The dip stick will contain markings for minimum and maximum fluid levels. However, it is important to note that to gain an accurate reading in some vehicles, you need to run the engine for a brief period, and even turn the steering several times in either direction while the car idles. If you are unsure whether this is the case for your vehicle, check the vehicle’s manual. Other vehicles provide two sets of markings or graduations on the cylinder or on the dip stick. One set is for when the engine has been running and one for when it has been ideal. These may be marked as hot and cold. It is important to differentiate between the two sets of minimum and maximum markings to ensure you do not get a false reading. Again, if you are unsure, check your manual. If your fluid levels are low, then check for a power steering fluid leak before going any further. If there is nothing wrong with the fluid and there are no leaks in the system, then you can top up your fluid to the correct position and replace your cylinder cap. If there are any issues with the fluid, then it should be changed to reduce the risk of damage to the pump and other elements of your power steering system,

Q: How often should I change my power steering fluid?

Recommendations for checking your fluid levels vary between once a month and once a year. If you notice a change in color, a burning smell, or particles in the fluid, then the fluid needs to be changed. Similarly, if the power steering fluid pump begins to make noises or steering your vehicle at low speeds becomes more difficult, then these are signs that you may need to change your power steering fluid. You also need to check your vehicle’s manual as this will give you the specific fluid changing intervals for your make and model of car. While each fluid will recommend a changing interval, you should be guided first by your vehicle and the recommendations of the vehicle manufacturer.

Q: Can I just pour in some new power steering fluid instead of replacing all of it?

Whether you need to replace or refill your power steering reservoir depends on your vehicle, the fluid that you are using, and importantly, what you find when you open the reservoir cap. If you find that your fluid has changed color, has a burnt smell, or contains debris or particles, then the fluid needs to be changed. However, these are also signs that there may be further issues with the power steering. You will need to check for leaks, corrosion, and damaged seals before replacing the fluid. If there is nothing wrong with the fluid and no signs of corrosion or leaks, then you should be clear to top up the fluid levels. However, you should ensure that you are using the correct fluid and that it is the same as the fluid that is already in the reservoir. Mixing different types of fluids can cause problems. If in doubt check with your car’s manual and check the manufacturer’s details on the fluid itself.
