Crankshaft pulley
2. Remove the drive belt (see Section 16).
3. Holding the pulley from turning with the T30004 tool with the T30004 / 1 bolt, unscrew the pulley mounting bolt and remove the pulley (see resist. illustration).
Attention: After removing the pulley, do not rotate the crankshaft to prevent the chain from slipping off the pulley.
17.3 Bolts of fastening of the right support of the engine
4. Install the pulley and hand-tighten the new pulley bolt. The bearing surfaces of the bolt, pulley and bushing must not be lubricated.
5. Turn the crankshaft to the TDC position of the piston No. 1 (see Section 19).
6. Turn out bolts (1 and 3 on resist. illustrations) and remove the bracket (2) right coolant pipe.
17.6 Bracket mounting bolts
Note: When installing, tighten the bolt (1) with a force of 8 Nm, and the bolt (3) - with a force of 40 Nm.
7. Unscrew the service hole plug in the cylinder block and screw the T10340 locking bolt into it until it stops, with a force of 30 Nm (see resist. illustration). This bolt prevents the crankshaft from turning from TDC when the pulley bolt is tightened.
17.7 Tool T10340
8. While holding the pulley from turning with the T30004 tool with the T30004/1 bolt, tighten the pulley mounting bolt with a force of 150 Nm, and then tighten it to an angle of 90°.
9. Unscrew the T10340 locking bolt and tighten the service port plug to 30 Nm.
10. Further installation is carried out in the reverse order.
Timing chain cover
11. Remove the engine top cover. To do this, remove the screws (1 in illustration 15.2), unhook the coolant hoses (2) and pull the cover up.
Note: When installing, tighten the bolts to 8 Nm.
12. Turn out a bolt (1 per resist. illustrations) coolant pipes and remove the PCV hose (2) from the timing chain cover.
17.12 Coolant line (1) and PCV hose
13. Disconnect the ventilation line (1 per resist. illustrations), by pressing on the retaining ring.
17.13 Ventilation line (1)
14. Disconnect the hose from the adsorber (1 per resist. illustrations), leading to the intake manifold. Release the canister in the direction of the arrow (IN) and remove it from the bracket in the direction of the arrow (A).
17.14 Removing the EVAP canister
15. Give the bracket fasteners (3 on resist. illustrations) adsorber, unscrew the neck bolt (2), disconnect the low coolant level sensor connector and pull the wiring out of the expansion tank. Turn out bolts of fastening of a broad tank (1) and set it aside without disconnecting the coolant hoses.
17.15 Providing access to the casing
16. Remove the drive belt (see Section 16).
17. Remove the water pump pulley (see chapter 3).
18. Disconnect the connector (1 in illustration 5.13a) magnetic clutch of the compressor and remove the bolts (arrows). Remove the climate system compressor without disconnecting the refrigerant lines from it, and secure it to the hood lock holder with a wire so that the refrigerant lines are not stretched or kinked.
19. Remove the accessory bracket (see Section 16).
20. Remove the hollow bolt (2 to resist. illustrations) oil supply line (1) casing turbocharger (3) timing chains.
17.20 Oil line hollow bolt
21. Remove the alternator and intermediate roller (2 to resist. illustrations), rotate the crankshaft to TDC. Remove crankshaft pulley (see subsection above) and engine oil pan (see Section 21).
17.21 Fixing the generator and intermediate roller
22. Remove the front hood buffers from the upper sides of both front fenders. Insert plates T10311 on the right (And in illustration 5.47) and left (IN) sides in the direction of the arrows as far as it will go so that the arrows "R" And "L" on the plates pointed back. These plates are needed in order not to damage the wings. Install support MP9-200, hook its spindle on the right lifting eye and unload the right support (see resist. illustration).
17.22 Unloading the right engine mount
23. Remove the bolts (1-6 per resist. illustrations) and remove the engine mount.
17.23 Engine mount
24. Remove the bolts (1-6 and arrows on resist. illustrations) and remove the cover. Raise the engine slightly if necessary. The crankshaft bushing must remain in the casing. Remove the crankshaft front oil seal from the housing.
17.24 Timing chain cover fastener
25. Remove sealant residues from mating surfaces using an appropriate chemical agent and degrease them. Insert new O-rings into the back of the casing (see resist. illustration).
17.25 O-rings on the back of the casing
26. Apply to the indicated resist. place illustrations (1 and 2) spots of sealant D176 501A1 with a diameter of 10 mm and a thickness of 1 mm to prevent leaks between the casing and the joints of the cylinder head with its cover and cylinder block.
17.26 Sealing points
27. Install a new gasket on the centering sleeves. To facilitate centering, screw two M6x80 studs into the head and cylinder block. Slide the timing chain cover together with the crankshaft bushing over the studs and dowel sleeves.
28. Evenly, in a diagonal order, tighten the casing mounting bolts: M6 bolts - with a force of 10 Nm, and M10 bolts - with a force of 50 Nm.
29. Adjust the position of the engine mount (see Section 15).
30. Install the crankshaft front oil seal (see Section 18).
31. Install the crankshaft pulley (see subsection above).
32. Attach the turbocharger oil feed pipe.
33. Further installation is carried out in the reverse order.
