🔌 Function

The pipe carries coolant between points in the engine's cooling circuit, providing a fixed, sealed flow path. Correct routing and sealing at its connections maintain coolant pressure and consistent engine operating temperature.

⚠️ Common Signs of Failure

• Visible coolant seepage or dried coolant residue at the pipe joints or along its length
• Corrosion, pitting or scaling on the pipe body leading to weeping or pinhole leaks
• Loss of coolant level with no other identifiable leak source
• Engine running hotter than normal due to restricted or blocked coolant flow
• Cracked, distorted or damaged pipe ends preventing a proper seal at the connection

🛠️ Service Notes

• Offer the pipe up and check it reaches both connections freely before you tighten anything — a rigid pipe pulled into place is a pipe left under permanent strain, and strained pipes crack at the fittings in service
• Renew the sealing washers, O-rings or union seals that go with the pipe rather than reusing the old ones, and make sure the seats, faces and threads are clean
• Keep the ends capped while you work and blow or flush a pipe through before fitting; anything left inside goes straight into the oil, fuel or coolant system
• Tighten unions and banjo bolts evenly to the figures in the workshop manual for your engine — overtightening distorts the seat and starts the leak you were trying to cure
• Refit every clip and support bracket in its original place and keep the pipe clear of hot or moving parts so it cannot chafe or be shaken to failure
