⚙️ Key Features

• Upper hose in the 5.0GXiCE exhaust-thermostat circuit

• Rated for warm pressurised coolant
• Hose only; clamps and adjoining hoses are separate
• Engine type: Volvo Penta 5.0-litre V8 catalyst marine gasoline engine

🔌 Function

Transfers coolant between the exhaust thermostat and the engine/exhaust cooling circuit while preserving the factory flow balance.

⚠️ Common Signs of Failure

• Coolant seepage around a clamp
• Hose hardening from exhaust heat
• One exhaust bank running hotter than the other
• Hose collapse during cool-down

🛠️ 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
