The head of the block of cylinders can be removed on the established engine, and this operation is sketched further. If the engine is already removed, all spadework is already spent.

The prevention Do not remove a head of the block of cylinders at temperature of the engine more than 40 ° C.

Disconnect the plug of a "mass" wire from АБ.

Merge from cooling system cooling liquid (item 19.1.1).

Disconnect hoses of a cooling liquid from a head of the block of cylinders.

Open all electric connections on a head of the block of cylinders.

Remove the air filter:

Fig. 390. To remove the air filter, disconnect: 1 — a hose going to a vacuum regulator of system рециркуляции ОГ; 2 — the gauge of the mass expense of air; 3 — an air inlet; 4 — an inlet hose

- Disconnect from the case of the air filter a hose 1 (fig. 390), going to a vacuum regulator of system рециркуляции ОГ;

- Separate штекерную колодку the gauge 2 mass expenses of air;

- Disconnect a sleeve of an air inlet 3;

- Cast away three spring collars of fastening of a cover of the air filter;

- Disconnect an inlet hose 4 from a forward part of the car and remove it from the case of the air filter.

Fig. 391. Removal of a cover of the engine: 1 — a hose of forced air; 2 — заглушка

Uncover the engine and disconnect a hose of forced air. Remove заглушку 2 (fig. 391) and a spring clip. Press a cover in a direction of an arrow and disconnect a hose of 1 forced air from an inlet collector.

Fig. 392. Removal of a cover of a head of the block of cylinders: 1 — a hose; 2 — safety caps; 3 — a spring collar

Uncover heads of the block of cylinders (the ventilation case картера remains on a head of the block of cylinders). Disconnect a hose 1 (fig. 392) from a cover of the block of cylinders, ослабьте a spring collar 3 inlet hoses and disconnect a hose. Remove safety caps 2 (two are shown by arrows) and turn away three nuts located under them. Uncover heads of the block of cylinders.

For engine dismantle it is necessary to raise the engine, to remove a forward hydraulic support of the engine, a collar of an engine mount and to remove a gear belt. For this purpose fix the engine строповочными loops and raise it by means of the lift so that to unload an engine mount. Turn away an engine mount from a hydraulic support (2 bolts) and from an engine mount collar (3 bolts). Be convinced that the engine is reliably fixed in trailing position.

Lift a forward part of the car and remove protection картера. Disconnect an arm of the pipeline of the pump of the hydraulic booster of a steering (1 bolt).

Fig. 393. Turn away bolts 1 and 2

Turn away a collar of an engine mount from a forward part of the engine (fig. 393). After untwisting of bolts at once lower the car on wheels.

Remove поликлиновой a belt and the top safety cover gear приводного a belt.

Remove a gear belt as it is described in corresponding section.

Disconnect all pipelines of system of injection which are connected with the pipelines fixed on a body and закупорьте them.

Disconnect from turbochargerа an exhaust pipe.

Disconnect the oil pipeline going to turbochargerу.

Remove or unbend aside draught of start of the cold engine.

Fig. 382. An order of untwisting of bolts of a head of the block of cylinders. At installation of a head of the block of cylinders bolts tighten in return sequence

In specified before sequence (fig. 382 see) turn on шестигранным a key bolts of fastening of a head of the block of cylinders, take bolts and remove a head of the block of cylinders. Remove a lining of a head of the block of cylinders.
