Power Steering Fluid Reservoirs – Key Components of the Steering System

Power steering fluid reservoirs are among the most crucial components supporting the proper operation of the power steering system. They are found in almost all modern passenger vehicles and vans, playing an essential role in ensuring driving comfort and safety.

What is a power steering fluid reservoir?

A power steering fluid reservoir is a specially designed container, usually located in the engine bay. Its role is to store the hydraulic fluid used in power steering systems. Maintaining the right level and quality of this fluid ensures smooth steering operation, reduces friction and lowers the risk of damaging other steering system components.

Most common failures of power steering reservoirs

Users most frequently report the following issues:

  • Leaks and cracks – Aging material, cracks, or mechanical damage often result in fluid leaks.
  • Contamination and residues – The buildup of impurities in the reservoir reduces the power steering system's effectiveness.
  • Worn or damaged seals – Faulty seals allow fluid leaks or air ingress into the system.
  • Fluid discoloration – Changes in fluid color may indicate reservoir material degradation or contamination.

How to identify a faulty power steering fluid reservoir?

Signs of reservoir malfunction include heavier steering, frequent fluid loss, visible stains under the car, or unusual noises when turning the wheel. Regular checks are recommended for early problem detection.

Is it worth replacing the power steering reservoir?

Any sign of malfunction or leak should prompt immediate reservoir replacement to prevent more severe issues like steering pump failure, noises, or, in extreme cases, loss of vehicle control. Replacement reservoirs are available for a wide range of makes and models.

How to choose the right reservoir?

Always use the car's OE number or VIN, and check the exact vehicle year and engine version. This ensures you select the right reservoir fully compatible with your power steering system.

FAQ – frequently asked questions

Does any power steering reservoir fit any car? — No, each must match the vehicle's model, year, and engine version.

When to replace the power steering reservoir? — Replace whenever there is damage, leakage, or contamination. Regular inspections are recommended during routine maintenance.

What are the symptoms of a faulty reservoir? — Fluid leaks, sudden drops in fluid level, noises during steering, felt resistance, or a strange fluid appearance.
