  5. 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.
  6. 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.
  7. Car front also establish to Poddomkratta it on props.
  8. Give bolts and release plastic screw clips of fastening of protection of a case. Remove protection.
  9. On the models equipped with the air conditioner:
    1. 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.
    2. Give the lower bolts and nuts of fastening of the compressor.
    3. 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.

  1. 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.
  2. Give coupling dome fixture to an engine plate. Turn out bolts of fastening of intensifying arms, remove arms from the engine.
  3. 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.
  4. 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.
  5. Hang out the engine by means of the suitable lifting equipment, having removed the weight of the power unit from the support.
  6. Give nuts of fastening of support of the engine to the block of cylinders and bolts of fastening of support to the chassis.
  7. 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.
