Prevention

On engines 2.1 liters, because of limited access in a motor compartment, for removal of a head of the block of cylinders it is necessary to remove the engine.


Sequence of tightening of bolts of fastening of a head of the block of cylinders


Removal

PERFORMANCE ORDER
1. Disconnect the negative plug from the accumulator.
2. Merge cooling liquid from the cooling system.
3. Remove inlet and final collectors. Alternatively remove an inlet collector, unscrew fastening of a final collector and disconnect it from a head. In this case the final collector can remain on the place together with a turbocompressor.
4. Remove inlet and final collectors. Alternatively remove an inlet collector, unscrew fastening of a final collector and disconnect it from a head. In this case the final collector can remain on the place together with a turbocompressor.
5. Fix a collector with a turbocompressor as appropriate. At the same time do not allow deformation of the tube bringing oil to a turbocompressor.
6. Disconnect and remove hoses of return of fuel from fuel nozzles.
7. Disconnect pipelines of supply of fuel from fuel nozzles and the fuel pump of high pressure and remove pipelines.
8. Unscrew a nut of fastening and remove a glow plug food wire.
9. Remove a hose of cooling liquid from the back left end of a head of the block of cylinders.
10. Disconnect a small hose of cooling liquid from the forward end of a head of the block of cylinders from a gear belt.
11. Take a fuel returnable hose from suspension brackets on a head of the block of cylinders and displace aside.
12. Remove an accelerator cable from the fuel pump of high pressure.
13. Remove the case of the fuel filter / thermostat.
14. Unscrew a nut or a rack of fastening of a suspension bracket of a hose of cooling liquid and move a suspension bracket to the end of a head of the block of cylinders.
15. Remove a camshaft pulley.
16. Remove the mechanism of a tension of a gear belt and the right engine mount.
17. Shoot the directing video of a gear belt.
18. Unscrew a bolt of fastening of a forward plate of the engine to a suspension bracket of installation of the fuel pump of high pressure.
19. Unscrew a nut and a bolt of fastening of a suspension bracket of the generator and fuel pump of high pressure and remove a forward plate of the engine.
20. Gradually unscrew bolts of a krpepleniye of a head of the block of cylinders as it should be, the return shown on rice. Sequence of tightening of bolts of fastening of a head of the block of cylinders.
21. Take bolts together with washers.
22. For separation of a head from the block of cylinders establish in openings under bolts two steel cores bent at right angle and, pressing them up and down, separate a head from the block of cylinders. Do not separate a head from the block of cylinders, inserting between the interfaced surfaces the lever since it can damage laying and the interfaced surfaces on a head and the block of cylinders.
23. Remove a head from the block of cylinders and laying.

Installation

PERFORMANCE ORDER
1. Turn the crankshaft clockwise before installation of all pistons in the middle of a piston stroke.
2. Install the required laying on the block of cylinders with cuts from a flywheel. Check that the directing pin is established into place.
3. Install a head on the block of cylinders.
4. Process a carving part of bolts and the basis of heads of bolts means of Molykote G Rapid Plus.
5. Establish bolts with washers in a head and screw in them.
6. Gradually and consistently tighten bolts the required moment (a stage 1; see rice. Sequence of tightening of bolts of fastening of a head of the block of cylinders).
7. Repeatedly tighten bolts the required moment (stage 2).
8. Tighten bolts on the required corner. Further installation is made in the sequence, the return to removal.
