# 1660378 Hose Clamp | Genuine Volvo Penta Part

## 🔧 Product Description

This genuine Volvo Penta hose clamp is a formed retaining and support component used in the air-cleaner housing clamp. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it clamps the air-cleaner housing or cover so the filter element remains sealed against unfiltered-air bypass. Selection must be confirmed by OEM part number 1660378, the exact engine/product model, serial number and the installed assembly configuration.

## 🚤 Compatibility

## 🔌 Function

A hose clamp compresses a hose evenly around its mating spigot or fitting to create and maintain a leak-free joint. It holds that seal against internal pressure, vibration and thermal cycling during engine operation.

## ⚠️ Common Signs of Failure

-   Coolant, fuel or air leakage or weeping at the hose joint
-   Visible corrosion, rust or pitting on the clamp band
-   Loss of clamping tension so the hose can be twisted or pulled on the spigot
-   Stripped, seized or rounded tightening screw that will not hold torque
-   Cracked or distorted band, or a hose that has worked loose from its fitting

## 🛠️ 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
