⚙️ Key Features

• Factory hose clamp for coolant or breather hose connections
• Used in cooling, expansion-tank and crankcase-ventilation sections

• Maintains an even sealing load under vibration and heat
• Must match the original hose outside diameter
• Engine type: Volvo Penta 5- and 7-litre industrial diesel
• Quantity varies by assembly, most commonly two

🔌 Function

Secures the assigned coolant or breather hose to its pipe or housing.

⚠️ Common Signs of Failure

• Coolant or oil-mist leakage
• Clamp corrosion or loss of tension
• Hose damage beneath the clamp
• Repeated hose movement

🛠️ Service Notes

• Match the clamp to the hose outside diameter so the band closes well within its working range rather than at the very end of its travel
• Position it over the spigot behind the bead or barb, with the screw where a driver or spanner can still reach it once everything is refitted
• Tighten to seal, not to crush — an over-tightened worm-drive clamp cuts into soft hose and starts the leak you were trying to stop
• Renew clamps when a hose is changed rather than reusing them, and keep band, housing and screw all marine-grade stainless so the clamp does not corrode against itself
• Where two clamps are fitted to one connection, stagger the screw heads and recheck both after the first running period
