Porsche Steering Reservoirs & Tanks - Hydraulic Fluid Storage Parts
Steering Reservoirs and Tanks are essential components of Porsche hydraulic steering systems, storing and supplying power steering fluid to the pump and steering rack. Designed to maintain correct fluid levels, pressure stability, and contamination control, these components ensure smooth and reliable steering performance.
Available from Design911, Porsche steering reservoirs, tanks, and associated parts help maintain consistent steering feel and protect critical hydraulic components from premature wear or damage.
What Do Steering Reservoirs, Tanks & Parts Do?
Steering reservoirs and tanks manage hydraulic fluid storage and circulation.
Core Functions:
- Store power steering fluid at the correct level.
- Supply fluid consistently to the steering pump.
- Allow fluid expansion and pressure stabilisation.
- Filter contaminants from the hydraulic system.
- Support smooth and reliable steering operation.
Correct reservoir function is vital for maintaining hydraulic steering performance.
Why Do Steering Reservoirs & Tanks Fail?
Steering reservoirs and related components degrade over time due to heat, pressure, and fluid exposure.
Common Causes of Failure:
- Plastic fatigue or cracking from heat cycles.
- Seal and cap deterioration leading to fluid leaks.
- Internal filter blockage or contamination.
- Damage from vibration or incorrect installation.
- Age-related material degradation.
A failing reservoir can lead to fluid loss, aeration, and steering system damage.
When Should Steering Reservoirs & Tanks Be Replaced?
Timely replacement prevents steering system failure and fluid contamination.
Replacement Is Recommended When:
- Fluid leaks or cracks are visible.
- Fluid appears contaminated or foamy.
- Reservoir caps or seals no longer maintain pressure.
- Steering noise or inconsistent assistance occurs.
- Power steering components are being serviced or replaced.
Replacing worn reservoirs helps protect pumps, racks, and hydraulic lines.
Key Benefits
- Maintains correct hydraulic fluid supply
- Prevents contamination and aeration
- Supports smooth steering operation
- Protects pumps and steering racks
- Suitable for modern and classic Porsche models
