⚙️ Key Features

• Genuine Volvo Penta hydraulic hose assembly
• Factory-crimped high-pressure connections
• Designed for the original steering pump and cooler
• Correct length and routing
• Resistant to steering fluid, heat and vibration
• Engine type: V8 marine petrol

🔌 Function

Transfers hydraulic fluid between the steering pump, cooler, reservoir or steering actuator.

⚠️ Common Signs of Failure

• Heavy or intermittent steering assistance
• Cracked or chafed hose
• Fluid aeration or foaming
• Seepage around crimped fittings

🛠️ Service Notes

• Fit the assembly along its original run so the moulded bends and fixed ends sit naturally; forcing a hose to twist or bend tightly to reach it kinks the wall and shortens its life
• Push each end fully home over the stub so the clip lands behind the bead or in its groove, and fit new clips rather than reusing tired or distorted ones
• Tighten clips evenly and only enough to seal — over-tightening cuts into the hose wall and starts the next leak
• Support the assembly with its original clips and stand-offs, clear of the exhaust, belts and sharp edges, and check nothing rubs when the engine moves on its mounts
• Bring the engine up to temperature, then recheck the joints and clip tightness once the hose has been hot and pressurised
