22320922 Hose | Genuine Volvo Penta Part

🔧 Product Description

A moulded coolant hose used in the external keel-cooling circuit of the Volvo Penta D6-280A-A. Its bend profile, internal diameter and connection length are matched to the original cooling layout so coolant can circulate without kinking, rubbing or restriction.

• Engine Family: D
• HP Range: 280-400 HP

⚙️ Key Features

• Catalogued for the D6-280A-A external keel-cooling system
• Correct bend radius and hose-end dimensions
• Designed for engine-coolant temperature and pressure
• Helps maintain unrestricted flow through the keel cooler
• Hose only; clamps and flange fasteners are separate service items

🔌 Function

Carries closed-circuit engine coolant between the engine and the external keel cooler, allowing heat to be transferred through the vessel-mounted cooler.

⚠️ Common Signs of Failure

• Coolant seepage or dried residue at the hose ends
• Cracking, hardening, swelling or blistering
• Chafing against brackets or structure
• Hose collapse or internal delamination
• Rising coolant temperature or repeated coolant loss

🛠️ 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
