🔌 Function

Joins two parts of the coolant circuit and holds them in alignment, giving a sealed, supported route for coolant to pass between them.

⚠️ Common Signs of Failure

• Coolant weeping or crusted white or coloured deposits at the joint
• Level in the expansion tank dropping with no obvious external leak until the engine is warm
• Corrosion pitting or scaling on the sealing face when the joint is broken
• Threads or flange face distorted so the joint will not pull up square
• Sweet coolant smell in the engine space after running

🛠️ Service Notes

• Renew the seals or O-rings that sit at this joint at the same time - they are the usual reason the connection is off the engine
• Check the mating faces for pitting before refitting; a corroded face will leak again on a new connection
