23151561 Breather Pipe | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta breather pipe from the Cooling System group, weighing 0.151 kg. It supersedes 22802115, catalogued earlier as an air vent pipe, and covers its eight D series engine applications - so it releases trapped air from the coolant circuit.

⚙️ Key Features

• Breather pipe from the Cooling System group
• 0.151 kg
• Supersedes 22802115, catalogued earlier as an air vent pipe
• Covers the eight D series engine applications of the superseded number

🔌 Function

Releases trapped air from the coolant circuit so the system fills completely and the engine does not run with an air pocket.

⚠️ Common Signs of Failure

• Engine running hot or temperature swinging after a coolant change
• Header tank level rising and falling, or air bubbling in the tank
• Coolant seeping from the pipe joints
• Pipe blocked with scale or debris when blown through
• Corrosion or a pinhole in the pipe wall

🛠️ Service Notes

• Check the pipe is clear before blaming the thermostat for a poor fill - a blocked vent leaves air trapped in the engine
• Renew the sealing rings at both ends and bleed the system fully after fitting
