1. Lift and establish the car on supports. Remove the bottom guard of an impellent compartment, address to the Section Removal and installation of the bottom guard of an impellent compartment.

2. Spray all boltovy connections by means for rust dissolution. Give some time for dissolution.

3. Unscrew fastening bolts traverses around the catalytic converter.

4. Bring under release system a garage jack and lay wooden laying. The weight of system makes 35-45 kg.

5. Unscrew bolts of fastening and remove a reception pipe from a final collector (the petrol engine) or a turbokompressor.

6. Release fastenings on a transmission arm.

5. Petrol engine: Establish a reception pipe at a collector with a new sealing ring and evenly fix it new being self-stopped nuts in two steps effort of 30 Nanometers + 50 Nanometers.

6. Tighten all bolts and nuts. In the last turn fix to RKPP an exhaust silencer beam so that the exhaust silencer had no tightness. The moments of an inhaling of carving connections are given in Specifications.

7. Establish cross-section to a traverse, bolts of fastening tighten the moment of 20 Nanometers.

8. Start the engine and check tightness of system of release. For this purpose close the exhaust silencer a rag. By means of the assistant check leakages of the fulfilled gases (characteristic noise, feeling a hand).

9. Establish the bottom guard of an impellent compartment, address to the Section Removal and installation of the bottom guard of an impellent compartment.
