Power steering is a vital feature for drivers. While it comes with benefits, it may also cause difficulties and make handling and maneuvering more difficult. If you want everything to operate correctly, your car will need a power steering fluid to keep functioning, or everything could fail.

Like many other mechanical issues, power steering fluid leaks come up from time to time. And you must first determine what is causing the problem before attempting to solve it. Luckily if you catch it, you can repair it, but how much does it cost to fix a power steering leak?

While everything will depend on your unique situation, most power steering fluid system repairs cost between somewhere $500 and $650. However, the actual cost depends on what went wrong with the system, where you got it fixed, and your actual location of repair. For example, if you need to repair the hose, you’ll likely spend under $150 for the essential components plus labor.

What are the Causes of Power Steering Leaks?

Having an insufficient amount of fluid could cause damage to the vehicle and ultimately lead to costly repairs down the road. It also substantially raises your chances of being involved in an accident that might have been avoided. 

Overall vehicle usage and time are the most common causes of power steering fluid leaks. The “O rings” can lose shape and bulk gradually over time which can also significantly impact the seals. Seals will begin disintegrating into tiny fragments that will float in the fluid. When this happens, the components cannot function as intended, and the liquid will leak. Replacement is not an option for these seals, which can be inconvenient.

Ultimately it can boil down to timing for power steering fluid leakage. Specific components of all cars slowly decay as it gets older, which can be accelerated with miles on them. Every aspect of a car’s handling is influenced by power steering. It allows you to comfortably tackle bends and twists while remaining straight and narrow when necessary.

The system requires a large amount of power steering fluid to make this possible. The hydraulic fluid that allows the steering system to transmit power generates the necessary pressure on both sides of the rack-mounted piston in your automobile.

The following are the most typical sources of leaks:

  1. Seals and O-rings losing bulk and shape
  2. Seal fragments end up in the fluid
  3. Holes appear in supply hoses

Like most things with cars, the cost of fixing a power steering system leak can vary greatly and depends on the source. You may need to replace just a single component or the entire system.

The first step is always getting it inspected by a local mechanic or repair shop to determine its cause. The ultimate goal is to replace the hose, pressure valves, or whatever else appears to be broken. The seals may be damaged in rare situations, but this necessitates replacing the entire system, not just the seals. Hence the reason why you may have to go for a complete hose replacement.

How Much Does It Cost To Fix A Power Steering Leak?

When replacement of the entire power steering system typically costs somewhere between $500-$650, but some specific parts may be just the following:

  • A new hose: $100-$300
  • Pump replacement: $400-$800
  • Replacement of a pressure valve: 25-$60  
  • Labor: $40-$200

Although you can still drive a car with a power steering leak, it doesn’t mean you should. This is because the system has run empty, making taking turns much more difficult. As a response to having limited turning ability, you might end up drifting somewhat wider than you’re used to. This significantly raises your chances of being involved in an accident.

The lack of liquid can create additional heat, and other components in your vehicle may eventually deteriorate as a result. If you don’t take care of it right away, you could wind up with more severe problems in the not-so-distant future.

While fixing the power steering system might cost a few hundred dollars, it’s a small price to pay compared to the expense of replacing it. When weighing the ultimate cost to fix a power steering leak, consider how much more you’ll spend if you ignore the issue. Of course, you want your to be in excellent driving condition, so you, your passengers, and other travelers are safe.

So, when you’re trying to figure out how much it costs to fix a power steering leak, the answer might vary. But, it’s the type of thing that could continue to get worse and can be the reason your car stops suddenly in the middle of the road. If you think you might have an issue, it’s always better to err on the side of caution, considering the potential damage in the end.

Tips to Avoid Power Steering Leaks

If you don’t want to deal with the hassles from power steering leaks, a few precautionary steps can go a long way.

  • Don’t turn your wheels all the way - Power steering systems are relatively good with specific tolerances to significant pressure. Not pushing the system too far is a good start to avoid leaks. How far is too far? Well, try not to turn the wheel in either direction until they stop turning. Pushing the steering all the way puts significant strain on the pump, lines, and other components – eventually, you may spring a leak.
  • Monitor your serpentine belt - This long belt wraps around the cranks and pulleys under your car. If the serpentine belt starts to crack or slip, the steering pump will likely act up or stop working altogether. It takes a good while before you need a belt replacement, but you’ll have to replace it as soon as you see signs of stretching, cracks, or any damage.
  • Get a power steering flush - At around 100,000 miles, we recommend getting a power steering fluid flush. Then, do more flushes every 50,000 to 75,000 miles. Flushing helps recondition your O-rings, seals, and other leak-stopping components.
