🔌 Function

The mixing elbow injects raw cooling water into the exhaust gas before discharge into the wet exhaust hose.

Common signs of failure:

• External corrosion, cracking or pin-hole leakage

• Internal carbon, rust or salt restriction

• Cooling water entering the manifold, turbocharger or cylinders

• Steam, reduced cooling-water discharge or an abnormally hot exhaust hose

• Loss of power caused by excessive exhaust back-pressure
