The power steering system is responsible for making it easier to steer the vehicle, and a leak can cause the system to fail, making it difficult or impossible to control the vehicle.
There are several possible causes of a power steering fluid leak, including worn-out seals, damaged hoses, and a faulty power steering pump.
Symptoms of a power steering fluid leak may include difficulty steering, a whining noise when turning the steering wheel, and low power steering fluid levels.
Sometimes using a power steering stop leak product designed to seal minor leaks can fix the leak, or you may need to replace damaged components of the power steering system.
In this article we’ll discuss the top six causes of power steering fluid leaks and ways to diagnose and fix the problem.
What is Power Steering Fluid?
Power steering fluid is a hydraulic fluid that transmits power in a power steering system. The pressurized fluid decreases the amount of effort required to turn the steering wheel. Without power steering fluid, a car’s power steering system cannot function properly.
Explanation of How Power Steering Fluid Works
The power steering system is a complex network of components that work together to make turning the steering wheel a lot easier, especially when the vehicle is not moving.
Newer vehicles are often fitted with electric power assisted steering (EPAS), but older models rely on a system that uses fluid and a pump to assist with the steering.
For fluid assisted power steering, the power steering pump pressurizes the fluid, which is then distributed through hoses to the power steering gear. The gear then uses the pressurized fluid to assist in turning the wheels.
The power steering fluid also acts as a lubricant for the power steering pump and gear, preventing wear and tear on these components.
Over time, power steering fluid can become contaminated with dirt and debris, which can cause damage to the system. Regular maintenance, including flushing and replacing the power steering fluid, is necessary to help prevent damage and extend the life of the power steering system.
It is important to use the correct type of power steering fluid for your vehicle, as using the wrong type can cause damage to the system.
What is a Power Steering Fluid Leak?
When a car’s power steering system has a leak, it means that the power steering fluid is escaping from the system.
Power steering fluid is essential to the proper functioning of a car’s power steering system, which assists the driver in turning the wheels. Without power steering fluid, the steering will not properly respond as it ought to.
A power steering fluid leak can be caused by a variety of factors, including:
- Worn out or damaged seals and O-rings
- Loose or damaged fittings and hoses
- Cracked or damaged power steering pump or steering rack
- Debris or dirt stuck in the system
When a car’s power steering system has a leak, it can cause a number of symptoms that can make driving difficult and dangerous. For example, you may notice that the steering wheel is difficult to turn, or that it makes strange noises when turning.
You may also notice that the car is pulling to one side or the other, or that the steering wheel vibrates or shakes when turning.
It is important to address a power steering fluid leak as soon as possible, as it can cause serious damage to the power steering system and lead to costly repairs if the fluid levels drop too low. Driving with a power steering fluid leak can also be dangerous, as the car may become more difficult to control and steer.
What Causes Power Steering Fluid Leaks?
Power steering fluid leaks can be caused by a variety of factors including wear and tear on the vehicle, damaged or worn out seals, and loose connections. Over time, the O-rings and seals in the power steering system can lose flexibility, and tiny bits of the seals can end up in the fluid, causing leaks.
| Cause of Leak | Possible Severity of Leak | Explanation of Cause |
|---|---|---|
| Damaged power steering pump | Moderate to severe | The power steering pump pressurizes the fluid, which then helps turn the wheels by pushing on pistons mounted to the rack. Over time, the pump can become damaged or worn, which can cause it to leak fluid. |
| Leaking power steering hose | Moderate | The power steering hose carries the fluid from the pump to the steering gear. Over time, the hose can become damaged or develop leaks, which can cause fluid to leak out of the system. |
| Cracked or damaged power steering reservoir | Mild to moderate | The power steering reservoir holds the fluid that is used by the system. Over time, the reservoir can become cracked or damaged, which can cause fluid to leak out of the system. |
| Worn or damaged steering rack or gearbox | Moderate to severe | The steering rack or gearbox is responsible for converting the rotational motion of the steering wheel into the back-and-forth motion of the wheels. Over time, the rack or gearbox can become worn or damaged, which can cause fluid to leak out of the system. |
| Loose or damaged fittings | Mild to moderate | The power steering system is connected by a series of fittings that can become loose or damaged over time. This can cause fluid to leak out of the system. |
| Using the wrong type of power steering fluid | Mild to severe | Using the wrong type of power steering fluid can cause damage to the system and lead to leaks. It’s important to use the type of fluid recommended by the manufacturer. |
How Can Power Steering Fluid leaks be caused by wear and tear?
Power steering fluid leaks can be caused by wear and tear on the seals and other components of the power steering system. Over time, the seals and other parts of the system can become worn or damaged, which can cause fluid to leak out of the system.
For example, the power steering pump pressurizes the fluid, which then helps turn the wheels by pushing on pistons mounted to the rack. The seals on the pump and the rack can become worn or damaged over time, which can cause fluid to leak out of the system.
Similarly, the power steering hoses that carry the fluid from the pump to the steering gear can become worn or damaged over time, which can cause leaks. The power steering reservoir can also become cracked or damaged, which can cause fluid to leak out of the system.
In addition to wear and tear on the components of the power steering system, other factors such as exposure to extreme temperatures or the use of the wrong type of power steering fluid can also contribute to leaks.
