Product Information

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
