🔌 Function

Turns and routes exhaust gas from the manifold into the catalyst/exhaust outlet while coolant limits surface and exhaust temperature.

⚠️ Common Signs of Failure

• Coolant or exhaust leakage at the joint
• Internal corrosion or restricted water passages
• Soot staining or ticking noise
• Water intrusion into the manifold or cylinders
• Catalyst or oxygen-sensor faults caused by leakage

🛠️ Service Notes

• Clean the threads and sealing faces and check the bore is clear before fitting
• Fit new sealing washers, O-rings or gaskets where the original had them, and use thread sealant only where the manual calls for it — never on a joint that seals metal to metal on a cone or a machined face
• Set the elbow so the connection points the way the hose or pipe wants to run, with no strain, kinking or chafing on the line
• Tighten to the figure in the workshop manual for your engine and hold the mating fitting so it cannot turn with it
• Bring the system up to working pressure and temperature, check the joint, then check it again after the first proper run
