⚙️ Key Features

• High-temperature oil-resistant hose
• Factory-crimped end fittings
• Correct engine-specific length and routing
• Designed for pressure, vibration and engine movement
• Suitable for the assigned lubrication or oil-service circuit
• L=2056mm (Volvo assembly listing)
• 2 used per assembly

🔌 Function

The hose transfers or drains engine oil through the designated service or lubrication-system circuit.

⚠️ Common Signs of Failure

• Oil seepage at hose ends
• Cracked or hardened outer covering
• Bulging or soft hose wall
• Abrasion or chafing
• Falling oil level
• Restriction caused by kinking or internal collapse

🛠️ Service Notes

• Catch and contain the oil, and cap or plug the openings as soon as the hose is off; anything that drops into an oil gallery goes straight round the engine
• Fit to clean, undamaged spigots or unions, with new sealing washers or O-rings where the connection uses them and new clamps on any push-fit joint
• Let the hose take its natural curve with no kink or twist, and refit every clip and chafe guard — an oil hose that fails over a hot surface is a fire risk, not just a leak
• Tighten unions to the workshop manual figures for your engine rather than by feel, as oil fittings distort easily
• Refill to the correct level, run the engine, confirm oil pressure comes up promptly, check the joints hot, then recheck the level once it has settled
