22318366 Hose | Genuine Volvo Penta Part

🔧 Product Description

A moulded genuine Volvo Penta coolant hose used on the D4-210A-A marine diesel cooling system. It follows the original routing and bend profile, allowing the hose to clear surrounding components while maintaining unrestricted coolant flow between the designated cooling-system connections.

⚙️ Key Features

• Genuine Volvo Penta moulded coolant hose
• Specifically catalogued for the D4-210A-A cooling system
• Correct internal diameter, bend profile and connection length
• Designed for marine-engine coolant temperature and pressure
• Helps prevent kinking and contact with adjacent components
• Supports stable engine temperature and coolant circulation
• Hose only; clamps and mounting fasteners are not included unless supplied separately

🔌 Function

Carries engine coolant between the specified cooling-system components. Correct hose shape and unrestricted flow help the thermostat, circulation pump and heat exchanger maintain normal operating temperature.

⚠️ Common Signs of Failure

• Coolant leakage or dried coolant residue
• Cracks around the hose ends or bends
• Soft, swollen or oil-contaminated rubber
• Bulging under operating pressure
• Hose collapse or internal restriction
• Rising engine temperature or overheating
• Repeated coolant loss
• Chafing against brackets or adjacent components

🛠️ Service Notes

• Fit hoses only to clean, sound spigots — take off old rubber, scale and corrosion, and renew the spigot or pipe if it is pitted, because no clamp will seal a rough sealing face
• Push the hose fully home so the clamp sits behind the bead or barb rather than over the end of the spigot, and fit new clamps whenever a hose is renewed
• Let the hose follow its natural bend with no kinks and no tension on either connection, clear of hot surfaces and moving parts, with chafe protection wherever it passes a bracket, edge or bulkhead
• Use the correct grade of hose for the duty, and clamp to the standard the installation demands — twin clamps are normal practice on seawater and fuel connections below the waterline
• Refill, vent and run the engine, then check every joint hot and cold and recheck the clamps after the first running period as the hose beds down
