| |||
3 | Detach rear section of lower engine compartment paneling | Installation: Install engine compartment paneling only after engine test run. | |
4 | Unclip electrical connectors (G3/3x1, G3/4x1, G3/5x1, G3/6x1) and electrical lines for O2 sensors from retaining clamps | ||
5 | Disconnect the electrical connectors (G3/3x1, G3/4x1, G3/5x1, G3/6x1) of O2 sensors | ||
6 | Support the exhaust system (4) with a transmission jack and a transmission platform | ||
7 | Detach the catalytic converters (5, 6) from the exhaust manifolds by unscrewing bolts (7) | Installation: Clean connection points from combustion and corrosion residues, replace bolts. | |
| |||
8 | Unhinge the exhaust system (4) from the exhaust rubber mounts (8) | To simplify removal: Apply liquid lubricant to the retaining bracket (9) and on the holes of the exhaust rubber mounts. | |
Check exhaust rubber mount for wear, replace if required. | |||
Lubricant paste | |||

9 | Lower the exhaust system (4) and remove it completely | ||
10 | Install in the reverse order | ||
| Checking | ||
11 | Check installation position and unobstructed movement of exhaust system (4) | The exhaust system must be mounted free of tension, align exhaust system if required. | |
Danger! | Risk of accident caused by vehicle starting off by itself when engine is running. Risk of injury caused by contusions and burns during starting procedure or when working near the engine as it is running | Secure vehicle to prevent it from moving by itself. | |
12 | Conduct engine test run and inspect exhaust system (4) for leaks |
