22348759 Hose | Genuine Volvo Penta Part

🔧 Product Description

A genuine moulded coolant hose used in the separately mounted engine-heater circuit on Volvo Penta D13 industrial diesel installations. Its formed shape connects the heater plumbing without kinking and maintains the required coolant path for pre-heating the engine before cold starting.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD1371-75VE
• Volvo Penta TAD1351-53VE

• Engine Family: TAD

⚙️ Key Features

• Moulded hose for the separately mounted engine-heater circuit
• Designed for hot engine coolant and repeated thermal cycling
• Factory routing and connection geometry
• Supports effective coolant circulation through the heater
• Recommended replacement if hardened, swollen, cracked or disturbed during heater service
• Engine type: 12.8-litre inline-six turbocharged diesel, industrial application

🔌 Function

Carries engine coolant between the cooling circuit and the separately mounted electric heater so the block and coolant can be pre-warmed for improved cold starting, reduced warm-up wear and faster heater performance.

⚠️ Common Signs of Failure

• Coolant seepage or dried coolant staining at the hose ends
• Hose collapse or a kink that restricts heater circulation
• Slow or ineffective engine pre-heating
• Coolant loss or air entering the heater circuit after shutdown

🛠️ 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
