What does power steering fluid do?
Power steering fluid is a hydraulic fluid that is used in vehicles with power steering systems. The main function of power steering fluid is to transfer the force generated by the power steering pump to the steering gear, which helps to make the steering more effortless and easier to control.
The fluid provides the necessary pressure to assist the driver in turning the wheels and helps to ensure smooth operation of the power steering system. Power steering fluid also helps to lubricate the components of the power steering system, reducing friction and wear.
It’s important to maintain the proper level of power steering fluid in the vehicle, as low fluid levels can cause damage to the power steering pump and other components. It’s also important to have the fluid checked regularly and changed as needed, as over time the fluid can become contaminated and break down, reducing its effectiveness.

Causes of power steering fluid problems:
Contaminated/old fluid
As parts of the power steering system wear, the power steering fluid can pick up small metal particles. This can cause parts to wear and seals to become loose. In this case, you will need to get the leak repaired. Symptoms of contaminated fluid include:
- Power steering fluid appearing a brown, dark colour.
- Power steering fluid hasn’t been changed in over two years.
- Reduced power steering effectiveness
- Whining noises from your power steering pump
Power steering fluid leaks
A leak can cause power steering fluid to leave your vehicle, reducing the effectiveness of your power steering system. Leaks can occur in the hoses, seals and power steering pump. Symptoms of a power steering leak include:
- Red/brown fluid appearing under your vehicle.
- Reduced power steering effectiveness.
- Groaning/creaking noise when turning.
Damaged power steering pump and/or hoses
The power steering pump and hoses send the fluid out to the rest of the power steering system. If either of the components fail, you may notice the following symptoms:
- Whining noise when turning (also sometimes caused by a failing drive belt).
- Leaks from underneath the vehicle.
- Difficulty turning.
Symptoms of power steering fluid needing replacement
The following are some common symptoms of bad power steering fluid:
- Steering difficulties: If the power steering fluid is low or contaminated, the power steering system may not be able to provide adequate assistance to the driver, making it more difficult to turn the wheel.
- Whining or groaning noises: A bad power steering fluid can cause the power steering pump to make a whining or groaning noise, especially when turning the wheel.
- Steering shake: If the power steering fluid is contaminated, it can cause the steering wheel to shake or vibrate when turning, especially at low speeds.
- Leaks: Bad power steering fluid can cause leaks in the power steering system, which can result in low fluid levels and reduced power steering performance.
- Reduced power steering: If the power steering fluid is low or contaminated, the power steering system may not provide the same level of assistance as it did when the fluid was in good condition.
