Prevention
The head of the block of cylinders needs to be removed on the cold engine. At installation of a head it is necessary to use new bolts of fastening of a head.
|
1. Depressurize fuel system. Remove a weight wire from the accumulator. |
2. Merge cooling liquid from the cooling system and unscrew spark plugs. |
|
3. Take off a gear belt. Before removal of a gear belt turn a bent shaft of the engine back approximately on 60 ° (4 teeth) that will allow to install camshafts so that pressure of a valvate spring was evenly on all length of the camshaft. |
Engines of 1,6 l |
4. Remove an inlet and final collector. If the head of the block of cylinders does not understand, it can be removed together with collectors after performance of the following actions:
– disconnect a reception exhaust pipe from a final collector; – disconnect the electric socket from the oxygen sensor; – disconnect an air branch pipe and a vacuum hose from the air injector valve. |
5. Remove casings of camshafts. |
6. Remove pulleys of camshafts and single pulleys of a gear belt. |
7. Unscrew bolts of fastening of a back casing of a gear belt to a head of the block of cylinders. |
8. Unscrew a bolt of the pump of the amplifier of steering and move it from a head aside. |
9. Disconnect electric sockets from the DIS block and the sensor of temperature of cooling liquid on a head of the block of cylinders. |
10. Weaken collars and disconnect the top hose of cooling liquid connecting a head of the block of cylinders and a radiator. Weaken a collar and disconnect the hose of cooling liquid connecting a head of the block of cylinders and a broad tank. |
11. Disconnect from a partition of a motor compartment hoses of supply of cooling liquid to a heater to merge cooling liquid from the block of cylinders. After discharge of cooling liquid repeatedly connect both hoses going to a heater. |
12. Working in a certain sequence, weaken bolts of fastening of a head of the block of cylinders on 1/3 turns for each pass before full unscrewing of bolts (see rice. Sequence of tightening of bolts of a head of the block of cylinders). |
|
13. Remove a head of the block of cylinders from the block of cylinders. |
.14. Remove laying of a head of the block of cylinders. |
L engines 1,8 and 2,0 |
15. Remove inlet and final collectors. If the head of the block of cylinders does not understand, it can be removed together with collectors after a detachment of all hoses and electric wires. |
16. Uncover a head of the block of cylinders. |
17. Remove pulleys from camshafts. |
18. Unscrew a bolt of fastening of draft of the compensator of torque from an end face of a head of the block of cylinders. |
19. Unscrew bolts of fastening of a back casing of a gear belt to a head of the block of cylinders. |
20. Weaken collars and disconnect the top hose of cooling liquid connecting a head of the block of cylinders and a radiator. Weaken a collar and disconnect the hose of cooling liquid connecting a head of the block of cylinders and a broad tank. |
21. Disconnect from a partition of a motor compartment hoses of supply of cooling liquid to a heater to merge cooling liquid from the block of cylinders. After discharge of cooling liquid repeatedly connect both hoses going to a heater. |
