844750 Tube | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta tube for the fresh water side of the cooling circuit, weighing 0.092 kg and listed for 9 applications across the TMD, MD and TAMD series engines. It is grouped under Instruments in the parts listing even though the note places it on the fresh water circuit, so match it by fitment rather than by group.

🔌 Function

⚠️ Common Signs of Failure

• Coolant weeping or dripping from the ends of the tube
• Coolant level falling slowly with no obvious external leak
• Green or white crusted deposits along the tube
• Tube kinked, dented or chafed where it passes a bracket
• Union threads corroded or seized

🛠️ Service Notes

• Renew the sealing washers or O-rings at each union rather than reusing them
• Support the tube in its original clips — an unsupported run work-hardens and cracks at the union
