Power steering fluid is a type of hydraulic fluid that is used in steering systems to assist in turning the wheels of a vehicle. It helps drivers steer their vehicle with ease by reducing the amount of force needed to turn the steering wheel.
It is typically made up of a combination of mineral oil and additives that help to improve vehicle performance and longevity. The fluid is stored in a reservoir that is located near the power steering pump. That circulates the fluid through the system.

Power Steering Fluid Types
| ATF (Automatic Transmission Fluid) | It is the most common type of steering fluid and is used in most vehicles. It is a hydraulic fluid that is designed to operate under high pressure and temperature conditions. |
| Synthetic | Fluid is made from synthetic base oils and is designed to provide better performance than traditional ATF fluids. Synthetic fluids are often recommended for high-performance or heavy-duty vehicles. |
| Mineral oil-based | This type of fluid is made from a base of mineral oil and is often used in older or classic cars that were designed to use this type of fluid. |
| HFM (Highly Friction Modified) | It is specifically designed for use in vehicles that require a higher level of friction reduction, such as luxury vehicles or sports cars. |
How To Check Fluid Level?
- Locate the fluid reservoir: The fluid reservoir is typically located near the power steering pump. It is driven by a belt attached to the engine.
- Check the fluid level: The reservoir will have markings indicating the minimum and maximum fluid levels. Make sure the vehicle is on level ground and the engine is off before checking the fluid level. Remove the cap from the reservoir and check the fluid level against the markings on the dipstick or the side of the reservoir.
- Add fluid if necessary: If the fluid level is below the minimum marking, you will need to add more fluid. Be sure to use the type of fluid recommended by the vehicle manufacturer. Slowly pour the fluid into the reservoir, checking the level frequently until it reaches the proper level.
- Inspect the fluid: Take a moment to inspect the color and consistency of the fluid. If it appears dark or has debris in it, it may be time to have the fluid changed or the power steering system inspected by a qualified mechanic.
What Are The Uses Of Power Steering Fluid?
Reducing steering effort
Steering fluid helps to reduce the amount of force required to turn the steering wheel, specially at low speeds or when the vehicle is stationary. This makes it easier for the driver to steer the vehicle, specially in tight spaces or when parking.
Protecting power steering components
Fluid lubricates and cools the power steering pump and other components, helping to prevent damage due to friction and heat.
Preventing leaks
It helps to maintain the seals and hoses in the power steering system. Reducing the likelihood of leaks that can cause the power steering system to fail.
Maintaining system performance
Fluid helps to maintain the performance of the power steering system by providing consistent hydraulic pressure to the steering gear or rack. It allows for smooth and responsive steering.
Why Is Replacing Power Steering Fluid Important?
Maintaining system performance: With Time, It can become contaminated with dirt, debris and other contaminants. This can cause the fluid to lose it’s ability to transmit hydraulic pressure effectively. Leading to reduced power steering performance and difficulty turning the steering wheel.
Preventing damage to the power steering system: Dirty or contaminated steering fluid can cause damage to the power steering pump and other components. This can lead to leaks and other problems that can be expensive to repair.
Extending the life of the power steering system: Regularly replacing fluid can help extend the life of the power steering system. This can help you avoid costly repairs and replacement of the power steering system.
Improving safety: A properly functioning power steering system is essential for safe driving. Replacing it can help ensure that your power steering system is functioning properly. It can help you avoid accidents and other safety hazards on the road.
How To Flush The Fluid?
| Locate the fluid reservoir | It is located near the front of the engine compartment and has a cap marked with a power steering symbol. |
| Drain the old fluid | You will need to disconnect the return hose from the power steering pump and let the fluid drain into a container. You may need to use a flare-nut wrench to loosen the fitting. |
| Refill the system | Once the old fluid has been drained, reconnect the return hose to the power steering pump and refill the system with new fluid. |
| Turn on the engine and turn the steering wheel | This will circulate the new fluid through the system. |
| Repeat the process | You may need to repeat the flushing process several times until the new fluid runs clear. |
| Check the fluid level | After running the engine for a few minutes, check the fluid level and add more if necessary. |
