🔌 Function

Carries coolant between fixed points in the engine's cooling circuit, holding the flow path rigid where a flexible hose would sag, chafe or collapse.

⚠️ Common Signs of Failure

• Coolant loss with no obvious hose leak, and a crusty deposit along the pipe
• Temperature creeping up as flow is restricted by internal scaling
• Damp or stained joints where the pipe meets its hoses
• Pinholes or pitting through the pipe wall, usually at the lowest point
• Corrosion under the clamps found once the hoses are pulled back

🛠️ Service Notes

• Renew the hoses and clamps at each end while the pipe is out, since they are usually the same age
• Refill and bleed the cooling system properly and check for leaks at working temperature
