- Disconnect hoses of a coal adsorber from steel tubes on the engine.
- Establish drain capacity under the steering pump, weaken a collar of fastening of a returnable hose, disconnect a hose and merge hydraulic liquid of system of strengthening of a wheel. Give a hollow bolt on the pump, - try not to lose copper sealing washers.
- Tie up hoses of system of hydrostrengthening of a wheel away from a working zone, having wound them pure неворсящейся with rags in order to avoid hit in system of dirt.
- Car front also establish to Poddomkratta it on props.
- Give bolts and release plastic screw clips of fastening of protection of a case. Remove protection.
- On the models equipped with the air conditioner:
- Weaken a lock-nut of a tension roller and, rotating the screw-driver an adjusting bolt, take off a driving belt from a compressor pulley.
- Give the lower bolts and nuts of fastening of the compressor.
- Turn out the top fixing bolts, lift the compressor and fix it on a mudguard of the left wing.
Do not weaken fastening of lines of high pressure of the compressor in order to avoid damage of injuries and frostbites as a result of direct contact with coolant. Besides, loss of coolant will result in need of a recharge of system.
- Give nuts of fastening of a flange of a reception pipe of system of production of the fulfilled gases to a final collector, an otstykuyta a reception pipe, without changing its situation on the car.
- Give coupling dome fixture to an engine plate. Turn out bolts of fastening of intensifying arms, remove arms from the engine.
- Give fixing bolts and remove a starter from the engine, - perhaps it is necessary to overcome some resistance connected about need of destruction of a layer of sealant.
- On models with AT give fixing bolts and remove a rotation converter cover plate. By means of the suitable lever, turn the engine for a driving disk so that access to one of bolts of fastening of the converter opened. Having turned out a bolt repeat the procedure for the remained fixture. Wring out the rotation converter towards transmission.
- Hang out the engine by means of the suitable lifting equipment, having removed the weight of the power unit from the support.
- Give nuts of fastening of support of the engine to the block of cylinders and bolts of fastening of support to the chassis.
- Slightly raise the engine and remove support. Lower the engine on the chassis for simplification of access to the top bolts of fastening of a dome of coupling.
- Give the top bolts of fastening of a dome of coupling to the engine.
- By means of a thin knife or other suitable tool cut a sealant layer on coupling dome perimeter, - try not to damage at the same time the interfaced surfaces.
- Carefully lift assembly of the engine and advance it on the car. On models with RKPP track that the main shaft of the transmission freely left coupling assembly. On models with AT take care of that the converter of rotation did not drop out of the case.
- With extreme care, trying not to damage fragile components, take assembly of the engine from the car. In case of existence of the slightest uncertainty it makes sense to spend time for preliminary removal of the knots creating a hindrance.
Installation in the basic is made upside-down.
- Take care of careful cleaning of the interfaced surfaces of a dome of coupling and the engine. Impose a sealant pillow on a flange of a dome.
Tightness of landing of a back plate to the engine is also extremely important as it prevents leak of water in a coupling dome.
- On models with RKPP do not forget to center by means of the special tool the conducted clutch plate on a flywheel, only after it tighten basket fixture (see the Head Stsepleniye).

- Switch off ignition.
- Remove the air duct and the muffler installed between the case of a throttle and the measuring instrument of an air stream.
- Instead of a detachment of fuel hoses from a gasoline pump weaken collars and disconnect a returnable fuel pipe from the fuel pressure regulator, and a fuel supply hose - from the fuel highway.
- Except the generator disconnect an electrical wiring also from the air regulator located under the right forward corner of the inlet pipeline. Disconnect the main tire of grounding from an arm in a forward part of the inlet pipeline, and also a grounding wire from a pipeline wall.
- Instead of an electrical wiring detachment from the carburetor and the temperature sensor disunite three electric sockets located on an arm in a forward part of the inlet pipeline.
- Miss the procedure of a detachment of vacuum hoses of the device of stabilization of turns of idling of the models equipped with the air conditioner.
Remember that before a detachment of all wires and their hoses it is necessary to mark surely.
- You make installation upside-down, taking into account the next moments:
