Opel Astra, Zafira

1. On models 1.4, 1,6 and 1.8 l DOHC uncover маслозаливной mouths, turn out fixing screws and remove a protective casing of the engine. Establish into place a cover маслозаливной mouths.

2. On l models 2.0 turn out fixing screws and remove a protective cover of candles from a cover газораспределительного the mechanism.

3. On models 1.6 of l SOHC and 2.0 l if marks of high-voltage wires are not visible, put it. Disconnect ВВ from spark plugs, — pull for a tip, instead of for a wire.

4. On models 1.6л SOHC, 1.4 and 1.8 l DOHC the ignition module is established between cases of camshafts, is direct over spark plugs, — disconnect from it electroconducting. Turn out fixing screws and remove the module of ignition from a head of cylinders. If the module "has become attached" and does not give in to branch, screw in its carving apertures pair of long bolts М8 and try to use them as handles.

5. Spark plugs on some of considered models are deeply drowned in candle niches, therefore for their reversing the extension piece of a drive of a key is required. Having put on a candle a head, connect a drive and, accurately rotating a collar counter-clockwise, turn out a candle.

6. Verify the turned out candle with the card of conditions resulted on a photographic insert that will allow to estimate the general condition of the engine qualitatively.
7. Check of a condition of candles gives good representation about an engine condition. If on an insulator of the central electrode completely there are no traces of any adjournment, it says about repauperization of an air-fuel mix, or that excessively "hot" candle (heat removal from an insulator to the case on "hot" candles is used occurs much less intensively, than on "cold").
8. Presence on electrodes of a black deposit testifies to mix reenrichment and if the deposit thus still has an oily consistence, it is necessary to think also of more detailed estimation of degree of deterioration of internal components of the engine.
9. The touch of a golden or grey-brown shade on an insulator confirms serviceability of a condition of the engine and correctness of configuration of an air-fuel mix.

10. All engines in a standard complete set are equipped by multielectrode candles. Installation of interelectrode backlashes on such candles is made on manufacturer and any updatings does not require.

11. At use non-standard candles with one lateral electrode (that is not recommended), on the foreground there is a factor of correctness of installation of the interelectrode backlash which size defines intensity искрообразования and, as consequence, correctness of ignition of a mix and development of process of its combustion in all modes of operation of the engine. Installation of interelectrode backlashes should be made according to instructions of manufacturers of candles.

12. Measurement of size of an interelectrode backlash on candles of adjustable type is made by means of special щупа wire type.

At updating it is necessary to turn in only a lateral electrode, — attempts of deformation of the central electrode are fraught with irreversible damage of an insulator. The nozzle for updating of position of an electrode usually is included into the complete set щупа.

If to measurement of a candle backlash it is applied usual щуп лезвийного type, it is possible to consider a backlash adjusted correctly when an edge () щупа take place in it with easy resistance.

13. Before candle installation make sure that the carving tip is densely screwed, and a carving on the case and an external surface of a candle are well cleaned.

14. Manually acquire one of new candles in a corresponding aperture in the engine. Having made sure that the candle is not warped in a carving, tighten it with demanded effort (at presence near at hand динамометрического a key). For simplification of procedure наживления candles pull on its shaft a piece of a flexible fuel hose. The probability of failure of a carving as at the slightest закусывании the hose will start to be turned simply is thus excluded. Operating in a similar manner, establish all remained candles.

15. On models of a corresponding complete set before to connect to spark plugs ВВ of a wire, execute procedures of service of the last (see more low).
16. Connection ВВ of a wire is carried out by vrashchatelno-progress of its tip, — last should sit down densely on a candle shaft (pay attention to marks of wires). On models without ВВ electroconductings establish the module of ignition and tighten its fixture with demanded effort.

1. Check begins with external survey of isolation of wires at the working engine. Tyre out the car in a dark premise, start the engine and make sure of absence искрообразования on wires. Искрообразование is a sign of breakdown of isolation. Try not to touch moving components in an impellent compartment. Make necessary marks on replacement of defective wires, then allow to the engine to cool down and start checks of a condition of a cover and бегунка the ignition distributor.
2. Check of candle wires is made serially in order to avoid infringement of an order of their connection at assemblage. Usually on isolation of firm wires there are corresponding marks. In case of absence that, put it independently by means of an adhesive tape and a marker.

3. Disconnect ВВ a wire from a spark plug (is better take advantage of the special tool). At all do not pull for a wire, only for its tip.

4. Attentively examine internal walls of a tip. Corrosion is usually shown in the form of fragile коркообразного a touch of white colour.
5. Pull a tip back on a shaft of the candle, make sure of density of its landing. In case of need again remove a tip and turn in plugs in a rubber cover.
6. Pure rags wipe a wire on all its length, completely having removed from a surface of isolation dirt and greasing traces. Examine wire isolation on presence of cracks, traces прогара and other damages. Try not to bend a wire under acute angles in order to avoid infringement of integrity of veins of a conductor in isolation.
7. Check up a condition of contacts of wires from outside the ignition module, — again pull only for a tip.
8. Replacement ВВ of electroconducting should be made the complete set, even in case of an exit from only one of wires.
9. Even at an excellent condition of system of ignition, at start in crude weather there can be failures, — in case of need spray system elements влагопоглощающим a spray, — ask in shops of automobile accessories.
