Repair and car operation

As from below the car possibly a detachment of some details, four steady supports which are applied also to a jack support are necessary. Before the work beginning in a motor compartment protect car wings a covering. The forward cowl at dismantle of the engine does not act in film.

The engine can be dismantled and without a transmission. Thus the points designated (*), it is not necessary to carry out. A transmission prop up a repair jack and wooden intermediate laying, then weaken connecting bolts an engine / transmission and wring out the engine from a transmission mount.

Depending on year of release and car model electric wires, hoses of depression and cooling liquid can be laid in a motor compartment differently. Before a detachment of the corresponding wire designate it a sticky tape. Dismantle of the 4-cylinder engine below is described, at dismantle of the 6-cylinder – act on sense.

PERFORMANCE ORDER

1. To open a cowl, pull the basic lever (3) on the left support of a cowl in the direction of an arrow and slightly raise a cowl that the lock lever was not fixed. Take the lock lever from the right support of a cowl and establish a cowl vertically. Prevention The left lock lever should be fixed in the top clamp. 2. Remove a covering (1) from a forward wall of a body. For this purpose unscrew a nut with a nakatny head (and) and release a rivet with a notch (b). 3. Disconnect from the storage battery a weight wire (–). Prevention The anticreeping code of radio is thus erased. 4. Disconnect from the accumulator plusovy a wire passing from the socket of the battery to the engine, stretch it through dividing partition and put on the engine. 5. Disconnect shtekkerny connection (X27/5) of the switch of pressure of oil. 6. Unscrew a wire (30) from the 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:      – hose (and) depression of the valve of regeneration;      – a depression hose 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 while a cover of a fuel tank and reduce superfluous pressure in fuel system. 11. Disconnect all electric wires conducting to the engine. For simplification of the subsequent installation previously mark wires a sticky tape. For example:      – disconnect shtekkerny connection from a lambda probe on a forward wall of a body;      – 2,2 l: dismantle a monitor covering behind a forward wall of a body, previously remove a plastic cover of a connector of wires;      – 1,8/2,0 l: remove the mnogoshtyrkovy socket and the item sensor of the crankshaft, and also the depression pipeline from the PMS device;      – disconnect separate wires from a block on the left wing, previously having uncovered a block;      – disconnect shtekkerny connection from темпомата;      – unscrew a "weight" cable from the holder of the block of hydraulics;      – conditioner: disconnect an electric wire from the conditioner compressor. 12. Disconnect the cable socket and take wires from holders. 13. Pipelines of fuel (17/2) and (17/3) designate a sticky tape and remove from the fuel (17) distributor. Previously disconnect hoses with clips. 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 jams. 16. Unscrew a retsirkulyatsionny hose (28) and a hose of a high pressure (29) for servorulevy management. In cars with adjustment on height in addition unscrew a hose of a high pressure (26) and an oil pipeline (27) for the double-circuit pump. 17. Raise the car. 18. Remove the bottom covering of a motor compartment. 19. Remove the fan with the hydraulic coupling. 20. Merge cooling liquid from a radiator. 21. Disconnect hoses of cooling liquid of a head of the block of cylinders behind and from the pump of cooling liquid in front. Previously weaken collars of fastening of hoses and disconnect completely. 22. Remove a radiator. Prevention For cars with the conditioner at once after dismantle of a radiator establish a protective cover on the condenser.
