17.1f Installation details of the central and rear part of the exhaust system of 2.0L diesel models (cLJA engine)
2. On all models, the middle and rear mufflers are installed at the factory as a single unit. If necessary, on diesel models with a CLJA engine, after removing the muffler assembly, they can be replaced separately by cutting the pipe and connecting its parts with a clamp, as described below.
3. Place of incision (2 on the accompanying illustration) marked on the outer surface of the pipe. Marks (1 and 3) indicate the locations of the double clamp (4).
17.3 Cut mark (2) and clamp installation marks (1 and 3) (4)
4. The ends of the clamp bolts should not be lower than the bottom of the pipe. The rear muffler should be positioned so that the distances (and in the accompanying illustrations) between the pipe and the bumper were equal to each other, and the distance (b) was equal for both pipes.
17.4 Aligning the rear muffler
5. To position the exhaust pipe without tension, loosen the double clamp nuts (1 in illustration 17.5a) and correctly set the intermediate relative to the mark at a distance (a) - 5 mm and tighten the nuts by hand. Then press the exhaust pipe forward so that the distance (a in figure 17.5 B) between the suspension/body and the suspension/middle muffler was 7-9 mm. Then tighten the double clamp nuts with a force of 25 Nm.
