Engine removal is necessary for spending in a following order:
- To disconnect at the switched off ignition of a wire and the storage battery;
- To check up all electric connections, to define the locations обвязок which are necessary for cutting. But, that them again to establish on former places, the last should be marked in appropriate way. It is possible to use instead of cable обвязок a sticky tape;
- The cowl of the engine is better for removing though to do it not necessarily. If this operation is spent, note a pencil on a metal surface of a cowl external contours of hinges to establish a cowl during installation in initial position;
- To establish the car on a viewing ditch or the lift or to bring under a forward part high enough and reliable support, to provide access to its bottom surface. Never to establish support under the oil pallet of the engine or a transmission. The car is necessary for establishing on support at lifting as it is described in подразд. 1.5 also it is shown on fig. 6 and 7;
- To merge a liquid from cooling system. For this purpose at first to unscrew a stopper of a broad tank, to accelerate plums of a cooling liquid. To weaken a collar of the bottom hose of a radiator and to take out a hose. To disconnect a hose of system of cooling from the thermostat case. The heater crane should be opened, that all cooling liquid could flow out from the heater block. To keep cooling liquid for a reuse if its kind and service life does not cause doubts;
- To deduce a cable of a drive of management of coupling from gearing with the lever of deenergizing of coupling as it is described in section 7. In it recommendations about carrying out of check of coupling which should be carried out before engine installation also are made.
The cars equipped with the steering mechanism with the amplifier:
- To dismantle the steering mechanism with the amplifier according to recommendations in corresponding section and to fix its wire on an arm. Hoses thus remain on the pump. To dismantle a broad tank of a steering and to fix it.

Removal of the holder of the lock of a cowl of the engine
As the engine is taken out from a motor compartment upwards forward the holder of the lock of a cowl it is necessary to dismantle together with the details fixed on it. In the presence of air conditioner it is necessary to consider resulted above the recommendation about placing of details after dismantle. Places of fastening of the holder of the lock are shown on fig. 16. For removal of the holder it is necessary to make the following:

Fig. 16. Knot of fastening of the holder of the lock of a cowl: 1 — the holder of the lock with the attached details; 2 — a special bolt, 5 Н·м; 3 — a bolt with шестигранной a head, 23 Н·м




- To open all штекерные connections and to disconnect hoses of system of cooling;
- To take a cable of a drive of the lock of a cowl;
- To dismantle a forward bumper. For this purpose to turn away 17 details specified in fig.;

Removal and installation of a forward bumper: 1 — a bumper; 2 — bolts with head Torx Т30 (seven), 6 Н·м; 3 — распорная a nut; 4 — the rubber shock-absorber; 5 — bolts with шестигранной a head (four), 5 Н·м; 6 — a bolt with шестигранной a head (two), 1,5 Н·м (only for large bumpers); 7 — a spoiler; 8 — насечная a rivet; 9 — a cover of deepening for a towing hook




- To weaken collars of highways of the conditioner of air (if it is);
- To turn out bolts 2 (fig. 16 see) and bolts with шестигранной a head 3;
- Cautiously to deduce upwards forward the holder of the lock in gathering with all details fixed on it. At the subsequent installation to watch that at fastening on a body the holder of the lock was not deformed;
- To dismantle балансирную a transmission suspension bracket. For this purpose to turn on specified by an arrow on fig. 18 nut 1, having fixed from проворачивания a bolt head;

- To dismantle the air filter according to recommendations (section 6 see). To mark an arrangement of all hoses connected to the filter, and to disconnect from the filter. All open apertures to close pure rags;
- To disconnect a wire of thin section from the coil of ignition and to take out a wire of average section from the coil;
- To disconnect a wire of the gauge of pressure of oil from язычкового contact;
- To disconnect from clips a wire of the gauge of temperature (on a cylinder head to take out the tip);
- To disconnect all tips in a motor compartment;
- To disconnect from clips of a wire of the switch of lamps of a backing on the top party of a transmission (for what preliminary to take away a rubber cap). To mark all wires connected to clips that they could be attached, as before, and to disconnect wires from clips;
- To disconnect both hoses of giving of a cooling liquid and a heater radiator on a head of the block of cylinders after easing of collars (from a highway and the thermostat case). The cooling liquid Thus can follow;
- To disconnect a vacuum hose of the amplifier of a brake drive from an inlet collector;
