Steering fluid8/31/2023 ![]() There is no set volume of fluid for power steering systems each car model will have its own unique requirements. How Much Power Steering Fluid Does My Car Need? If you’re not comfortable flushing your power steering, get it done as part of your next service. If you’ve come up to this milestone, make sure you follow the correct procedure and do not simply adding more fluid to the old. Some manufacturers will recommend you have your power steering flushed replaced (not topped up) every 60,000 miles or so. However, it’s not an easy task and should not be carried out unless the individual performing the power steering flush knows exactly what they are doing. For those with mechanical knowledge and experience, it is possible to flush a system at home. The entire system washed out, then the new fluid is added. Flushing requires the power steering fluid to be drained from the vehicle. It’s important to note that a power steering top up is very different from replacing power steering fluid, otherwise known as “flushing”. If low, it’s time to top up! You can easily do this yourself - this guide will go into further detail as to how. You can check the current levels of power steering fluid by accessing the reservoir under the bonnet. There may be a squeaking or squealing noise when you turn, or you may feel some unusual vibrations in your wheel as you drive. Your steering may be firmer and more difficult to handle than usual. There are a number of telltale signs that your power steering fluid needs topping up. Hydraulic systems are often used in other mechanical objects, like aeroplanes, making it easy for pilots to manoeuvre huge machines. Power steering was developed to take away the strain of turning.Īs you turn the wheel, the force you exert on it builds pressure in the hydraulic fluid system, which transfers more energy with less effort, making it much easier to control your vehicle with a light touch.

Turn the wheel, it should turn smoothly each way, and the pump should not whine if it’s still in good condition. This will eventually disappear once the air is gone and may take a few minutes. You will notice the fluid cavitating which is perfectly normal. Keep an eye on the fluid and add when needed. Some vehicles may require more than a few times. Turn the steering from lock to lock right and left about four times each way or until all the air has been bleed out of the system. With the engine running, leave the cap on but loose just to prevent any fluid from bubbling out. DO NOT drive the vehicle without bleeding the system as you do risk damaging the pump, but it can be removed off the ramps or from being elevated. Continue this until the fluid level has stopped dropping. With the engine off, turn the steering to full lock right and left which will push air from the system. You will notice bubbling in the reservoir which is perfectly normal. Refill the system with the new fluid with the engine off. rubber gloves (used in the video is Permatex Black 5 mil Nitrile Disposable Gloves #08184).Old or worn power steering fluid can cause problems besides premature failure on system parts which includes a whining pump, hard steering, and generating more heat. ![]() As for maintenance intervals, this does depend between manufacturers, but as a generalized figure it should be at around every 60,000km/40,000miles or every three years. Some vehicle’s never had the fluid replaced which greatly increases the risk of components failing in the system which can be very costly to repair. ![]() Some power steering systems use a form of hydraulic fluid and others will use an automatic transmission fluid. Just like any other fluids in your vehicle, power steering fluid also needs to be changed as it does break down over time losing it’s lubricating, heat transfer, and power transfer efficiency qualities. ![]() Video tutorial on how to change the power steering fluid on your vehicle if it’s equipped with a drain plug. ![]()
