🔌 Function

Routes exhaust and cooling flow through the designed bend between the manifold and catalytic converter.

⚠️ Common Signs of Failure

• Exhaust ticking or soot around the flange
• Coolant leakage or unexplained coolant loss
• Internal corrosion or blocked water passages
• Catalyst-efficiency faults caused by exhaust 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
