The power steering reservoir stores the fluid that supplies the steering pump, ensuring consistent hydraulic pressure for smooth and easy steering. Over time, the reservoir can crack, leak, or develop clogged filters, leading to fluid loss or contaminated fluid circulation. Replacing a faulty reservoir prevents steering issues and protects the pump and rack from damage.

What is a power steering reservoir replacement?

This service involves removing the old or damaged reservoir and installing a new one. The system is then refilled with fresh fluid and bled of air to restore proper steering performance.

Why do you need a power steering reservoir replacement?

A damaged or leaking reservoir cannot hold fluid properly, causing low levels, aerated fluid, or contamination. This leads to noisy steering, heavy wheel movement, and increased wear on the pump and rack.

Common signs you need a power steering reservoir replacement

• Visible power steering fluid leaks around the reservoir
• Low or rapidly dropping fluid levels
• Whining or groaning noises when turning the wheel
• Discoloured or foamy fluid in the reservoir
• Cracks or visible damage to the reservoir

What happens during a power steering reservoir replacement?

A mechanic will:

1. Inspect the reservoir for leaks or cracks
2. Drain the power steering fluid
3. Disconnect hoses and remove the old reservoir
4. Install a new manufacturer-approved reservoir
5. Reconnect hoses and refill with fresh fluid
6. Bleed the system to remove air and restore smooth operation
7. Test drive to ensure proper steering function

How much does a power steering reservoir replacement cost?

Replacement typically costs $200–$450, depending on the vehicle. Costs may be higher if hoses or fluid sensors also need replacement.

Is it unsafe to drive with a bad power steering reservoir?

Yes. A cracked or leaking reservoir can cause sudden fluid loss, leading to heavy steering, pump damage, and possible loss of control. The issue should be repaired immediately.
