Removal
1. Disconnect the electrical wiring from the fuel switch and glow plugs.
2. Clean the feed pipes at the points of connection with the pump and nozzles with a cold cleaning agent and unscrew. Close the openings with appropriate caps. Do not change the bend shape of the pipes.
3. Remove the glow plugs and injectors (see subsection 2.17.7.2 and subsection 2.17.7.5).
Installation
1. Fine-tuning of the cylinder head of a diesel engine is not permitted.
2. Depending on the piston protrusion, cylinder head gaskets of different thicknesses are installed. When replacing a gasket, pay attention to the designation of the old gasket and install a new gasket with the same designation. Black arrow - part number, white arrow - cutouts/holes.
3. Before installing the cylinder head, screw the guide pins 3070 into the outer holes from the inside.
4. If you don't have any guide pins at hand, make guide pins for centering the cylinder head. To do this, saw off the heads of the old cylinder head bolts and cut a slot for a screwdriver.
5. Screw the guide pins into holes 8 and 10 (see subsection 2.6.1). Turn the crankshaft by the belt pulley so that all pistons are at approximately the same height.
6. Install the cylinder head.
7. Install the remaining 8 cylinder head bolts with washers and tighten by hand. Always replace the cylinder head bolts.
8. Unscrew the guide pins with a screwdriver, install the remaining 2 cylinder head bolts with washers and tighten by hand.
9. The cylinder head bolts of a diesel engine are tightened in the same way as those of a petrol engine, but in addition, they are tightened again on a warm engine.
10. Replace the cylinder head cover gasket only if damaged.
11. Install the glow plugs (see subsection 2.17.7.2).
12. Install the injectors (see subsection 2.17.7.5).
13. Clean the connections of the supply pipes with a cold cleaning agent. Tighten the union nuts to a torque of 25 Nm.
14. Connect the wires to the fuel switch and glow plugs.
15. Check the start of the high pressure fuel pump (see subsection 2.17.7.6).
16. Tighten the cylinder head bolts on a warm engine. To do this, warm up the engine while driving, leave it running at idle speed until the radiator fan turns on (oil temperature above 50°).
17. Stop the engine.
18. Unscrew the cylinder head cover.

19. Tighten the bolts with a rigid wrench, without first loosening them and in one go by 1/4 turn (90°). Observe the tightening sequence (see Fig. Cylinder Head Bolt Tightening Sequence).
20. Install the cylinder head cover.
Attention! Retightening of cylinder head bolts after 1000 km of running is not allowed.
