Comment. The work is shown on the example of engines 21114 and 21124 (1,6i), where the sealing ring is installed between the flanges of the exhaust pipe and the additional muffler. On engines 2111 and 2112 (1,5i) the ring is installed between the exhaust pipe flanges and the catalytic converter, but the operation is similar.
Advice. If the tightness of the swivel joint is broken and it cannot be restored by replacing the springs of the coupling bolts, it is necessary to replace the sealing ring.
To perform the work, a viewing hole or overpass is required.
Attention! Before proceeding with the repair, make sure that the elements of the system are not hot.
Removing
1. Key by 13 mm unscrew the two swivel pinch bolts.
2. Remove the bolts together with the springs.
3. Slightly spread the flanges to the sides. Using a slotted screwdriver, remove the metal-graphite sealing ring from the seat.
Installation
We install a new metal-graphite ring in the reverse order.
Recommendation. Bolt springs should preferably be replaced with new ones.
