Note. Replacing the muffler exhaust pipe ring is shown on a VAZ 2110 car with an engine 21124 (1,6i), where the sealing ring is installed between the flanges of the exhaust pipe and the additional muffler. On the VAZ 2112 engine (1,5i) a metal-graphite ring is installed between the exhaust pipe flanges and the catalytic converter, but the replacement work is carried out in the same way.
Recommendation. 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 metal-graphite ring of the receiving pipe.
To carry out repair work, a viewing hole or overpass is required.
Removing
1. With a 13 mm wrench, we unscrew the two coupling bolts of the swivel of the exhaust pipe of the muffler...
... and remove the bolts along with the springs.
2. Slightly spread the flanges to the sides. Using a slotted screwdriver, remove the metal-graphite sealing ring of the intake pipe from the seat.
Installation
We install a new muffler intake pipe sealing ring and all removed parts on the car in the reverse order of removal.
Recommendation. Bolt springs should preferably be replaced with new ones.
