⚙️ Key Features

• Genuine cooling-hose clamp
• Correct band profile and clamping range
• Provides even sealing pressure around the hose
• Used with original Volvo Penta coolant plumbing
• One clamp supplied; hose and pipe components are separate
• Engine type: Volvo Penta diesel cooling system, model dependent
• Quantity varies by assembly, most commonly two

🔌 Function

Compresses the coolant hose uniformly onto its pipe or fitting to maintain a pressure-tight seal through temperature and vibration cycles.

⚠️ Common Signs of Failure

• Coolant seepage around the hose end
• Clamp no longer maintaining tension
• Corroded, cracked or stripped adjustment mechanism
• Hose movement or rotation on the fitting
• Band damage cutting or distorting the hose

🛠️ 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
