Vehicle Repairs. We've Got What It Takes.
The febi range of high-quality, specialist hydraulic oils provide optimised low-temperature performance. They are based on advanced additives and selected mineral base oils, and are developed specifically for use in central hydraulic systems such as power steering, convertible roof mechanisms and hydro-pneumatic suspension systems.

Quality by Conviction:
Oils from febi are not universal products, but rather are tailored to the special requirements of vehicle manufacturers. Only the right oil can guarantee the safe functioning of the hydraulic systems in the vehicle. High-quality hydraulic fluids from febi are therefore precisely matched to the special requirements of vehicle manufacturers.

Power Steering Pressure Hose – Left Hand Drive (LHD)

OE Match replacement power steering pressure hose for left-hand-drive Porsche Cayenne 955 models equipped with the 4.5-litre V8 engine.

Fits:

  • Porsche 955 Cayenne S 4.5L V8 2003-06
  • Porsche 955 Cayenne Turbo 4.5L 2003-06
  • Porsche 955 Cayenne Turbo S 4.5L 2006>>

This high-pressure hydraulic hose is designed to carry pressurised power steering fluid between components of the steering system, helping maintain smooth, responsive steering assistance.

Manufactured as an original-style replacement, it is ideal for repairing leaking, deteriorated or damaged power steering hoses and restoring reliable hydraulic steering operation.

What Does the Power Steering Pressure Hose Do?

The pressure hose carries hydraulic fluid under high pressure from the power steering pump towards the steering rack.

This hydraulic pressure provides steering assistance, reducing the effort required to turn the steering wheel, particularly when parking or manoeuvring at low speeds.

Why Does It Fail?

Over time, exposure to engine heat, vibration and hydraulic pressure can cause the hose and its connections to deteriorate.

Common problems include:

  • Cracked or hardened rubber hose sections
  • Leaks around crimped fittings or connections
  • Corrosion of metal pipe sections
  • Damage caused by vibration or contact with nearby components
  • Fluid loss resulting from ageing seals or fittings


When Should It Be Replaced?

Replacement is recommended if you experience:

  • Visible power steering fluid leaks
  • Falling power steering fluid levels
  • Heavy or inconsistent steering assistance
  • Whining noises from the power steering pump
  • Cracked, swollen or damaged hose sections

Inspect the pump, reservoir, steering rack and associated connections before replacement to identify the source of any leak.

For left-hand-drive vehicles only.

Fitment may vary according to engine specification and steering system configuration. Confirm compatibility using the original part number or vehicle VIN before ordering.

Installation Notes

Power steering hoses must be installed with the correct routing and fittings to prevent leaks, rubbing or damage.

Following installation, refill the system with the Porsche-specified hydraulic fluid, bleed the steering system correctly and check all connections for leaks.

Porsche Cayenne 955 Power Steering Hoses & Hydraulic Steering Parts

The hydraulic power steering system fitted to the Porsche Cayenne 955 relies on high-pressure hoses to deliver fluid between the steering pump and steering rack.

Ageing hoses can develop cracks, leaks or damaged fittings, resulting in fluid loss, increased steering effort and potential damage to the power steering pump.

Power steering return line / return hose - Cooler to reservoir.
Genuine Porsche Original Equipment (OE) power steering return hose/line designed specifically for select Porsche Cayenne (955) models. It serves as the low-pressure return path for hydraulic power steering fluid as it flows from the steering fluid cooler back to the reservoir.

Fits:
Porsche 955 Cayenne 2003 - 2006

Diagram ref no 17

This hose carries power steering fluid back to the reservoir after it has circulated through the cooler, helping maintain a continuous and stable fluid loop. By returning cooled fluid to the reservoir, it contributes to consistent steering assist performance, reduces fluid temperature, and helps protect pump and rack components from heat-related wear.

Function:
Installed between the power steering cooler outlet and the reservoir inlet, the return line:
• Provides a low-pressure return path for steering fluid
• Maintains secure, leak-free connections at both cooler and reservoir
• Ensures proper fluid flow and pressure balance in the steering circuit
• Resists heat, vibration, and fluid exposure over extended service life.
Because it is a factory-supplied part, the hose’s ends, bends, and lengths are engineered to fit precisely without interference with surrounding brackets, heat sources, or suspension components.

Over time, rubber hoses can suffer from internal degradation, cracking, swelling, or hardening due to heat, age, and contamination. A compromised return line can lead to fluid leaks, loss of steering assist performance, air ingestion into the system, and premature wear on the power steering pump and rack. Installing a new return line ensures correct material performance, proper clamp location, leak-free operation, and the peace of mind that comes with factory-approved reliability.

When to replace:
•  Visible fluid leaks around the line or hose ends
•  Cracks, soft spots, bulges, or hardened hose walls
•  Air bubbles, foaming, or hissing noises from the steering system
•  During cooler, pump, or reservoir service
•  Preventive replacement on high-mile vehicles

About Power Steering Pipes / Hoses / Radiators

Porsche Power Steering Pipes, Hoses & Radiators | Design911 Hydraulic Components for Precision Steering

Power steering pipes, hoses, and radiators are vital for maintaining smooth, responsive steering performance in your Porsche. These components transport and cool the hydraulic fluid that powers the steering system, ensuring precise control, minimal resistance, and consistent handling under all driving conditions. A well-maintained hydraulic circuit not only enhances steering feel but also protects your steering pump, rack, and associated components from wear and overheating.

At Design911, we offer an extensive selection of power steering pipes, hoses, and cooling radiators, engineered for exact fitment, reliability, and high-pressure performance. Manufactured using durable materials such as reinforced rubber, stainless steel, and aluminium, our range is ideal for servicing, restoration, and performance upgrades — keeping your Porsche’s steering system operating at its sharpest.

What Do Power Steering Pipes, Hoses & Radiators Do?

Power steering pipes and hoses transfer hydraulic fluid between the pump, rack, and reservoir, while radiators (or coolers) regulate fluid temperature for consistent performance.

Core Functions:
• Deliver hydraulic fluid to assist steering input.
• Maintain consistent pressure within the steering circuit.
• Prevent overheating of steering fluid during high-load use.
• Ensure responsive, effortless steering at all speeds.
• Reduce wear on the pump, seals, and steering rack.

Together, these parts form the backbone of your Porsche’s power steering system, ensuring smooth handling and precise feedback whether on the road or track.

Why Do Power Steering Components Fail or Degrade?

Continuous heat, pressure, and exposure to fluids can cause deterioration of hoses and pipes over time, while radiators may corrode or leak.

Common Causes of Failure Include:
• Cracked or brittle hoses from age or heat exposure.
• Corrosion or pitting in metal pipes.
• Leaks at joints or seals from fluid pressure fluctuations.
• Blocked or damaged steering coolers reducing efficiency.
• Contamination of hydraulic fluid causing internal wear.

When these components fail, drivers may experience stiff steering, fluid leaks, noise, or overheating — all of which can lead to expensive steering system damage if left unaddressed.

Why Replace or Upgrade Your Porsche Power Steering Pipes, Hoses & Radiators?

Replacing or upgrading these components restores safe, consistent hydraulic operation and improves overall steering precision. High-quality materials and modern design offer improved durability, pressure resistance, and corrosion protection.

Key Benefits:
• Restores smooth, consistent steering response.
• Prevents fluid leaks and overheating.
• Extends life of steering pumps and racks.
• Constructed from premium, heat- and pressure-resistant materials.
• Fits Porsche 911, 944, 968, Boxster, Cayman, Cayenne, and Macan models.
