Power steering fluid is essential for smooth and easy steering. Over time, the fluid breaks down, becomes contaminated, or loses its hydraulic properties, which can cause heavy steering, noise, or premature wear on the steering pump and rack. Replacing the fluid at regular intervals helps maintain safe handling and extends the life of the steering system.

What is a power steering fluid replacement?

This service involves draining the old fluid from the power steering system, flushing any contaminants, and refilling it with fresh manufacturer-approved fluid. The system is then bled to remove air and checked for leaks.

Why do you need a power steering fluid replacement?

Old or contaminated fluid can’t lubricate and protect the steering components properly. Replacing it prevents wear, reduces the risk of pump or rack failure, and keeps your steering responsive and quiet.

Common signs you need a power steering fluid replacement

• Steering feels heavy or stiff
• Whining or groaning noises when turning the wheel
• Power steering fluid looks dark, dirty, or smells burnt
• Foamy fluid in the reservoir
• Fluid has not been changed in over 50,000 km (or as recommended)

What happens during a power steering fluid replacement?

A mechanic will:

1. Inspect the power steering fluid for level and condition
2. Drain or extract the old fluid from the reservoir and lines
3. Flush the system to remove contaminants if necessary
4. Refill with fresh, manufacturer-approved power steering fluid
5. Bleed the system to remove trapped air
6. Test drive to ensure smooth, quiet steering

How much does a power steering fluid replacement cost?

Typically, a power steering fluid replacement costs $120–$250, depending on the vehicle and whether a flush is required. Vehicles with larger or more complex systems may cost slightly more.

Is it unsafe to drive with old or contaminated power steering fluid?

Yes. While your car may still steer, dirty or degraded fluid increases wear on expensive parts like the pump and rack. This can lead to sudden steering failure. Replacing the fluid is a cost-effective way to avoid major repairs and maintain safe handling.
