Disconnect from the accumulator плюсовой a wire which is passing from a socket of the battery to the engine, stretch it through dividing partition and put on the engine. 5. Disconnect штеккерное connection (Х27/5) the switch of pressure of oil. 6. Unscrew a wire (30) from a socket. 7. If there is a measuring instrument of weight of air, remove it. 8. Disconnect all hoses of depression which go to the engine. For example:      – A hose () depression of the valve of regeneration;      – A hose of depression to the right of an inlet pipe;      – A hose of depression of the amplifier of braking from an inlet pipe. 9. Disconnect a gas cable. 10. Open for a short while a cover of a fuel tank and lower superfluous pressure in fuel system. 11. Disconnect all electric wires conducting to the engine.

Preliminary disconnect hoses with clips. The prevention Enclose a rag as fuel thus follows. 14. Select a suitable syringe hydraulic oil from a tank of the amplifier of a steering. 15. Unscrew hoses and close stoppers. 16. Unscrew рециркуляционный a hose (28) and a hose of a high pressure (29) for серворулевого managements. In cars with adjustment on height in addition unscrew a hose of a high pressure (26) and маслопровод (27) for the two-planimetric pump. 17. Преподнимите the car. 18. Remove the bottom covering of a motor compartment. 19. Remove the fan with hydraulic муфтой. 20. Merge cooling liquid from a radiator. 21. Disconnect hoses of a cooling liquid of a head of the block of cylinders behind and from the pump of a cooling liquid in front. Preliminary ослабьте collars of fastening of hoses also disconnect completely. 22. Remove a radiator. The prevention For cars with the conditioner at once after radiator dismantle establish a protective cover on the condenser.
