⚙️ Key Features

• Moulded hose for the catalyst exhaust-thermostat circuit
• Correct bends for the 5.0-litre V8 installation
• Works with adapter 3595495 and the adjoining thermostat hoses
• Coolant- and heat-resistant marine rubber
• Hose only; clamps, adapters and thermostat housings are separate
• Engine type: Volvo Penta 5.0-litre V8 catalyst marine gasoline engine

🔌 Function

Carries engine coolant through the exhaust-thermostat branch so both exhaust banks reach and retain the designed operating temperature.

⚠️ Common Signs of Failure

• Coolant leakage or staining at the hose ends
• Soft, swollen or cracked hose wall
• Kinked hose reducing thermostat flow
• Uneven exhaust-bank temperature
• Overheating or catalyst-temperature faults

🛠️ 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
