– remove the forward panel of a motor compartment together with headlights;
– disconnect wires from the fan of cooling of the engine and remove their fastening from a radiator;
– weaken collars and disconnect the top and bottom sleeves of system of cooling from a radiator;
– remove a radiator together with the fan of cooling of the engine;
– disconnect hoses of system of cooling from unions on the engine and from a broad tank of system of cooling;
– disconnect all elements of a power supply system (the inlet pipeline, an accelerator cable, electric sockets of the sensor of provision of a butterfly valve, a plait of wires of system of injection of fuel, топливопроводы, hoses of system of cooling and vacuum hoses);
– note junctions of a plait of wires in a motor compartment;
– disconnect wires from the sensor of temperature of cooling liquid, the sensor of pressure of oil, the generator, the switch of transmission and the sensor of speed of the car, the sensor of temperature of engine oil, a starter, the central high-voltage wire of the coil of ignition, high-voltage wires of the distributor of ignition, the tire of connection with "weight" from a cover of a head of the block of cylinders;
– disconnect a heater hose from a partition of a motor compartment;
– disconnect a speedometer cable from a transmission.
For cars with a mechanical transmission:

– establish the lever of a choice of transfers to the situation "R";
– disconnect a gear shifting cable from the gear shifting lever;
– remove a bracket of a clamp of a cable and remove a cable;
– press hoses of cooling liquid, and then disconnect them from the refrigerator block;

Fig. 3.1. Support of fastening of the power unit: I\the back right; II\the back left;
III\lobby; 1-7-bolts.


– unscrew bolts of fastening of a back right support of I (see fig. 3.1 ) the engine;
– unscrew a bolt of a back left support of II;
– unscrew a nut of a forward support of III;
– check, whether all wires and hoses are disconnected from the engine and a transmission;
– lift the power unit the elevating device that it was released from support;
– take the power unit from a motor compartment the elevating device up and forward;
– disconnect a transmission from the engine.
Installation of the power unit is carried out in sequence, return to removal. Bolts and nuts of fastening of support of the power unit tighten the demanded moment (see подразд. 3.1.1) only after its installation on all support and rockings for ensuring its correct landing. After installation adjust an accelerator cable.
