⚠️ Common Signs of Failure

• Exhaust fumes or noise in the engine space
• Soot staining radiating from the flange joints
• Flange faces warped or eaten by corrosion
• Cracks in the casting, often at a flange corner or mounting boss
• Flange studs pulled or nuts loose from thermal movement

🛠️ Service Notes

• This is a heavy casting - support it during removal and fitting rather than leaving it hanging on the studs
• Only 122 grams separate this from outlet 78708705, so the superseded numbers 23518187 and 21562753 are the reliable way to tell them apart
• Renew all exhaust gaskets and any corroded studs and nuts
