1545816 Coolant Pipe | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta coolant pipe from the engine's cooling system group, carrying coolant between components in the circuit. It is applicable to the 10-litre TD, TWD and TAD industrial and generator-set engine families, and is supplied as an individual pipe rather than a kit. Fitment on later production engines is governed by a serial-number break, so confirm your engine serial number before ordering.

🔌 Function

The coolant pipe routes engine coolant between points in the cooling circuit, maintaining sealed flow so heat can be carried away from the engine to the heat exchanger or radiator. Correct flow through this pipe is essential to stable operating temperature.

⚠️ Common Signs of Failure

• Visible coolant seepage, drips or dried coolant residue at the pipe or its joints
• External corrosion, pitting or scaling that thins the pipe wall
• Loss of coolant from the system with no other identifiable leak point
• Engine running hotter than normal or fluctuating coolant temperature due to restricted flow
• Internal blockage or deposit build-up reducing coolant circulation

🛠️ Service Notes

• Confirm the engine serial break before ordering; the documented TAD1030GE later installation uses this pipe from SN 2100285979 onward.
• Renew disturbed seals and inspect the oil cooler and retaining-band assembly for corrosion or movement.
