22412988 Draining Hose | Genuine Volvo Penta Part

🔧 Product Description

Genuine short draining hose used in selected Volvo Penta D16 generating-set cooling systems. The hose connects the specified drain or low-point fitting to the adjoining cooling-system pipework, allowing controlled coolant discharge during maintenance. The documented hose length is approximately 50 mm, so end diameter and installed location must be checked rather than replacing it with a generic hose section.

🚤 Compatibility

Typically suits:

• Volvo Penta TWD1643GE
• Volvo Penta TWD1652GE

⚙️ Key Features

• Genuine Volvo Penta formed/short drain-hose component
• Documented nominal length approximately 50 mm
• Designed for engine-coolant temperature, pressure and chemistry
• Provides a flexible connection at the cooling-system drain point
• Accommodates engine vibration between rigid fittings
• Correct hose diameter and clamp positions are installation-specific
• Engine type: 16-litre inline-six turbocharged diesel generating-set engine

🔌 Function

Provides the flexible sealed connection at the coolant drain point, allowing coolant to be directed from the low point of the cooling system during servicing while isolating rigid components from vibration.

⚠️ Common Signs of Failure

• Coolant staining or leakage around either hose end
• Cracking, hardening, swelling or softening
• Blocked or restricted coolant draining
• Clamp cuts or permanent hose deformation
• Falling coolant level
• Hose collapse or separation during service draining

🛠️ Service Notes

• Around 50 mm long — check end diameter and clamp positions against the original before fitting, since a generic length of hose will not locate or seal correctly at this drain point
• Fits the D16 generator-set range (TWD1643GE, TWD1652/53GE, TWG1663GE, TWD1663GE and the TWD1682-83GE/TWD1672-73GE variants) — confirm the exact drain fitting it connects to
