🔌 Function

The pipe routes coolant between points in the engine cooling circuit, maintaining sealed flow so heat is carried away from the engine to the heat exchanger or radiator. A sound pipe is essential to keeping coolant pressure and circulation within specification.

⚠️ Common Signs of Failure

• Visible coolant weeping, dripping or crusted residue at the pipe or its joints
• Corrosion, pitting or scale build-up on the pipe body reducing wall thickness
• Loss of coolant level with no other identifiable leak source
• Overheating or erratic coolant temperature caused by restricted flow
• Cracks, deformation or damaged sealing faces found during inspection

🛠️ 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
