⚠️ 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 a mounting boss
• Flange studs pulled or nuts loose from thermal movement

🛠️ Service Notes

• At over nine kilos this needs supporting during removal and fitting - do not let it hang on the flange studs
• Renew all exhaust gaskets and any corroded studs and nuts, and check the flange faces are flat before assembly
• The two outlets are only 122 grams apart, so weight will not separate them - order by part number, using 21562753 as the old reference for this one
