Removal
1. Jack up the car and place it on supports.
2. Remove the crankcase guard and treat all exhaust system bolts and nuts with a rust remover. Wait for a while.
3. Loosen the connecting fasteners of the exhaust system sections and remove them from the rubber hangers.
4. Disconnect the lambda probe wiring connector and unscrew it with a special key.
5. Remove the ground connecting wire.
Installation
Attention! Always replace seals, nuts and bolts with new ones. To facilitate subsequent disassembly, it is recommended to coat the exhaust system nuts and bolts with high-temperature paste. Visually inspect the rubber suspensions and replace them if necessary.
1. If the exhaust pipes are not being replaced, clean their mating surfaces with sandpaper to remove carbon deposits and sealant residues before assembly.
2. Connect the electrical wiring.
3. Connect the exhaust system sections and tighten their clamp fasteners by hand.
4. Secure the exhaust pipe to the body using brackets and rubber hangers.
5. Center the tie bolt springs relative to the hole in the flanges and tighten the tie bolts and other fasteners.
6. Adjust the exhaust system so that it sits on the hangers without tension. Make sure that there is sufficient clearance between it and the bottom.
7. Check the exhaust system for leaks (see Chapter Vehicle settings and routine maintenance).
