## ⚙️ Key Features

-   Heavy-duty formed tensioning-band clamp
-   Supersedes earlier tensioning band 476659
-   Maintains uniform clamping load around a large hose or duct
-   Suitable for the original Volvo Penta hose and anchorage arrangement
-   Must be matched to the hose outside diameter and installation position
-   Engine type: Volvo Penta TD70 diesel

## 🔌 Function

The hose clamp compresses a coolant hose onto its spigot or connection to form a tight, pressure-holding joint. It keeps the hose retained in place despite engine vibration, thermal cycling and coolant pressure.

## ⚠️ Common Signs of Failure

-   Coolant seeping or dripping at the hose joint
-   Corrosion, pitting or rust on the band or screw housing
-   Stripped or seized tightening screw that will not hold torque
-   Loss of clamping tension allowing the hose to slip off the spigot
-   Cracked or distorted band after repeated retightening

## 🛠️ 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
