9. Disconnect pad a plait of wires from the gauge of 1 index of temperature of a cooling liquid and disconnect the holder 2 motor plaits from an arm.
10. Have a bite бокорезами (or knife) a collar of fastening of a wire to a hose, take a motor plait aside that it did not disturb to work …

THE NOTE
Collar of disposable use. At assemblage do not forget to replace with its new collar that the wire has been necessarily fixed.

11. … also separate pad a plait of wires of the gauge of concentration of oxygen.
13. Remove a drive belt газораспределительного the mechanism (Replacement and adjustment of a tension of a belt of a drive газораспределительного the mechanism and replacement of its tension roller »see«).
14. Turn out a bolt of fastening of a gear pulley of a camshaft, keeping a pulley from проворачивания, as is shown in a photo, inserted into apertures of a pulley handles пассатижей and the big screw-driver …
15. … and then remove a pulley.
16. Loosen the a collar of fastening of a hose of a radiator to a thermostat cover …
17. … also remove it from a cover branch pipe.
18. Remove a back cover of a drive газораспределительного the mechanism (Removal and installation of the oil pump »see«).
19. Disconnect колодки a motor plait of wires from the gauge of position throttle заслонки
20. … an idling regulator...
21. … and atomizers.
22. Take from a groove of sector of throttle knot a tip of a cable of a drive throttle заслонки
23. … and from an arm cut — rubber демпфер a cable also take a cable aside.
24. Disconnect hoses of system of ventilation картера from a cover of a head of the block of cylinders, the camshaft case, воздухоподводящего a sleeve and an inlet pipe (Clearing of system of ventilation картера »see«).
25. Remove воздухоподводящий a sleeve, having disconnected it from a branch pipe of throttle knot (Removal and installation of throttle knot »see«).
26. Disconnect колодки a plait of wires from the gauge of temperature of a cooling liquid of a control system of the engine …
27. … and the electromagnetic valve of system рециркуляции the fulfilled gases.
28. Disconnect from the union of a regulator of pressure of fuel a hose plum …
29. … and from the fuel filter — a taking away hose, having compressed clamps запорных elements of tips of hoses.

THE NOTE
Necessity of a detachment of a hose from the fuel filter, instead of from a stage is caused by that for its detachment from a stage the special adaptation (Removal and installation of a fuel stage »see«) is required, to use which expediently only at hose replacement.

30. Disconnect from branch pipes of throttle knot hoses of a supply and plum of a cooling liquid, having weakened collars of their fastening (Removal and installation of throttle knot »see«).
31. Disconnect from branch pipes of throttle knot a hose of a purge of an adsorber …
32. … and from an inlet pipe — a hose to the gauge of absolute pressure.
33. Loosen the a collar of fastening of a hose of the vacuum amplifier of brakes, having compressed пассатижами its unbent ears, shift a collar on a hose …
34. … also disconnect a hose from an inlet pipe.
35. Disconnect pad a plait of wires from the ignition coil.
36. Remove from spark plugs tips of high-voltage wires and remove wires, having taken out them from nests of the coil of ignition.
37. Loosen the an inhaling of the bottom bolt of fastening of a supporting arm of an inlet pipe …

Fig. 5.4. Sequence of an inhaling of bolts of fastening of a head of the block of cylinders

38. … turn out two top bolts of fastening of a supporting arm …
39. … also deduce from under an arm the holder of hoses of system of cooling.
40. Disconnect a reception pipe from a final collector («Replacement of a reception pipe» see).
41. Turn out ten bolts of fastening of a head of the block of cylinders to the block in sequence, return that that it is shown on fig. 5.4, in three steps: turn out bolts on a half-turn, turn out bolts for a half-turn, definitively turn out bolts.

THE PREVENTION
Bolts of fastening of a head of the block of cylinders it is possible to turn on only on the cold engine.

42. Take bolts and remove the camshaft case …
43. … a head of the block of cylinders in gathering with an inlet pipe and a final collector …

GOOD ADVICE
To remove a head of the block of cylinders it is more convenient with the assistant, as it heavy enough.

44. … and its lining.
45. Clear привалочные surfaces of a head of the block and the block of cylinders (surfaces should be dry and pure) …
46. … also remove oil from carving apertures in the block under bolts of fastening of a head.

THE PREVENTION
If not to remove oil from carving apertures under bolts of fastening of a head of the block at an inhaling of bolts in the block of cylinders there can be cracks, as oil incompressible.

47. Establish on the block of cylinders a new lining, having centered it on two directing plugs.
48. Establish a head of the block of cylinders in sequence, return to removal, taking into account the following:
– Necessarily replace a lining of a head of the block new, its reuse is not supposed;
– Necessarily replace new bolts of fastening of a head of the block as they are deformed at an inhaling and for a reuse are not suitable.
Tighten bolts on the cold engine in the sequence shown on fig. 5.4, in five stages: 1st — tighten bolts the moment 25 Н·м (2,5 кгс·м); 2nd — tighten bolts on a corner 60 °; 3rd — in addition tighten bolts on a corner 60 °; 4th — still in addition tighten bolts on a corner 60 °; 5th — definitively wrap bolts on a corner 10 °;

THE NOTE
After the first start-up of the collected engine, its warming up to working temperature and full cooling after a stop tighten in addition bolts of fastening of a head of the block of cylinders on a corner 30–50 °.

– Replace a reception pipe of system of release of the fulfilled gases new a lining, deformed at an inhaling of nuts of fastening.
49. Establish all details and knots in an order, the return to removal.
51. Adjust a tension of belts of a drive of the generator and the pump of the hydraulic booster of a steering (Check and adjustment of a tension of a belt of a drive of the generator and the pump of the hydraulic booster of a steering »see«), and also the conditioner compressor (Check and adjustment of a tension of a belt of a drive of the compressor of the conditioner »see«).
