Removal and engine DOHC installation


All instructions concerning removal and engine OHC installation are valid as well in this case. The engine is taken out from a compartment without a transmission. The transmission and a distributing box should act in film separately that it was possible to take out the engine without blocking through a transmission.


1. Disconnect a cable of weight and a positive cable from the storage battery.
2. Remove a cowl. Preliminary establish a cowl in vertical position and disconnect a hose of giving of a liquid to nozzles стеклоомывателя. Lead round a pencil hinges on a surface of a steel sheet of a cowl later to establish a cowl in former position. Turn away screws of fastening of hinges. Thus the assistant should keep a cowl. Remove a cowl and put it on well protected place. Enclose under cowl edges a thick rag.
3. Merge a liquid from cooling system (Section Refuelling of a cooler of system of cooling of the Head Current leaving and service) and close заглушками system hoses. To them between a broad tank of system of cooling and the pipeline of giving by a cooling liquid at the soaking up pipeline, a hose of tap of a cooling liquid from the soaking up pipeline and giving and water drainage hoses three hoses of a radiator, a hose concern a heater.
4. Disconnect a cable of weight from the storage battery of the engine in a point shown on иллюстр. The arrow specifies in a place of joining of a cable of weight of the engine.
5. Disconnect a cable plait from the engine. It has fastening in several places: in the multiitem tip and the socket on a wall of an impellent compartment, in the multiitem tip and the socket at branch of cable distributing of the engine ahead on the right, at the block of safety locks, at a temperature-sensitive element, at a measuring instrument of weight of air and at the oxygen gauge. It is recommended to mark connections for simplification of their further assemblage.
6. Remove a radiator and the cooling fan as it is described in corresponding section.
7. Put on a readily available place клинового a belt an arrow specifying a direction of its rotation. Turn a tension roller of a belt, as is shown in иллюстр., in an arrow direction so that a belt ослаб, also remove it.
8. Remove the pump of the hydraulic booster of a wheel. For this purpose turn away a bolt from the console and pump bolts. Remove the pump and adhere it on a wire to any element of a design. Do not open hydrosystem, the pump do not suspend on hoses.
9. In the presence of the conditioner remove the compressor. For this purpose disconnect an arm of the compressor from the block of cylinders and the unit console. Fastening is carried out by three bolts in front and four behind.
10. Release a cable of a drive throttle заслонки from the holder and remove.
11. Disconnect a vacuum hose from the soaking up pipeline.
12. Disconnect both топливопровода at trailer connections.

At opening of the pipeline being under pressure, there is a fuel emission. At all have no close a control lamp. At connection opening it is recommended to put on it a wrench and to cover it from above with a rag. After that slowly turn on a hollow bolt.

13. Turn away connection of an oil hose from a head of the oil filter. Pay attention to presence of a sealing ring.
14. Disconnect two hoses of a cooling liquid from the case throttle заслонки. Disconnect also the vacuum hose going to the adjusting valve of the evaporator.
15. Turn away four bolts of the fastening (1), shown on иллюстр., also remove the case throttle заслонки and the inlet pipeline.
16. Disconnect now a cable on the end шаровый heads. The cable fastens on a support a spring clip which is necessary for removing. After отпускания a clip the cable can be disconnected.
17. Turn on накидную a nut and disconnect a vacuum hose of the amplifier of a brake from the inlet pipeline.
18. If is available, remove from below the bottom protective sheet (the car for this purpose put on supports).
19. Расстыкуйте from the bottom party of the car (the car put on supports) штекерное connection of the gauge of oxygen. Turn away bolts of fastening of arms of system of release and remove a reception pipe with каталитическим neutralizer from the muffler.
20. Turn away bolts (1) and (2), shown on иллюстр. Also disconnect a reception pipe of system of release, with attached to it каталитическим neutralizer, from a final collector. Lower all knot downwards and take out.
21. Disconnect a hose of a cooling liquid from the pipeline.
22. Remove a transmission and a distributing box as it is described in corresponding section. After that on suspension brackets there is only one engine.
23. Fix on eyes of the engine cables or chains of the load-lifting mechanism and raise the engine. Remove a suspension bracket and lift the engine upwards, having separated it from suspension brackets. Watch to damaging any cable connection or the pipeline, and also behind to striking the engine about any elements in an impellent compartment. Operation is recommended to be carried out with the assistant.


The engine in sequence, by return to removal is established. The majority of the instructions concerning installation of engine OHC, are valid as well concerning engine DOHC. Топливопроводы of 15 Nanometers fasten the moment. Thus it is necessary to keep a key a nipple from damage by the inhaling moment.
