🔌 Function

The pipe connection provides a sealed, correctly aligned junction between coolant pipework and the component it feeds. It positions the pipe run accurately so hoses and clamps seat properly and coolant flow is unrestricted.

⚠️ Common Signs of Failure

• Coolant leakage or staining at the connection face
• Corrosion, pitting or scaling of the connection body
• Cracking at the flange, thread or brazed joint
• Distorted or damaged sealing face preventing a leak-free joint
• Repeated hose failure at the connection caused by a rough or corroded surface

🛠️ Service Notes

• Clean the threads and sealing face in the housing, and check the bore of the connection is clear before fitting
• Fit a new sealing washer, O-ring or gasket, and where a tapered thread is used seal it with the product the manual specifies rather than winding tape onto a fuel, oil or hydraulic joint
• Hold the connection at the correct angle for the pipe run as it is tightened, so the pipe meets it squarely instead of being sprung into place
• Tighten to the figure in the workshop manual, and do not try to cure a weep by pulling the joint up harder — strip it and look at the sealing face
• Pressure-test or run the system and check for weeping before closing up access, then check the joint again after the first period of running
