🔌 Function

Routes coolant along a fixed path in the cooling circuit, keeping the run clear of hot and moving parts where a hose would need supporting.

⚠️ Common Signs of Failure

• Slow coolant loss with staining or dried deposit along the pipe
• Damp joints where the pipe meets its hoses or unions
• Engine running warmer than usual as internal scale narrows the bore
• Pinholes or pitting through the wall, often at the lowest point of the run
• Corrosion and thinning under the hose clamps, found when the hoses are pulled off

🛠️ Service Notes

• Renew the hoses, clamps and any sealing rings at both ends while access is open
• Pipe 22820440 is the other item in this group, so check parts list for your engine before ordering
