The correct functioning of spark plugs – one of the most important conditions of effective operation of the engine. It is necessary, that on the engine spark plugs only the ordered type were established. At the serviceable engine cleaning of spark plugs – rare operation.

Arrangement of labels of identification
Arrangement of labels of identification of high-voltage wires (1) and the tool for removal of wires (2).

1. On the DOCH engine of 1,6 l remove a maslozalivny stopper, unscrew screws (are specified by shooters) and remove a casing from the top part of the engine. Establish a maslozalivny stopper into place.
2. On engines 1,8 and 2,0 of l unscrew screws and uncover spark plugs the top part of a cover of a head of the block of cylinders.
3. In the absence of labels on high-voltage wires (see rice the Arrangement of labels of identification) is necessary for marking them not to be mistaken at their further installation.
4. Remove high-voltage wires from spark plugs, having pulled for a candle tip.
5. Clear candles, using a brush, the vacuum cleaner or a stream of the compressed air that will exclude dirt hit in engine cylinders after a vyvinchivaniye of spark plugs.
6. Unscrew candles, using a candle key.
7. Visual control of a working part of spark plugs can show an engine condition. If the nasal part of an insulator of spark plugs pure and white, without a raid, it testifies to too poor mix. It also specifies that the candle too hot, that is heat from the central electrode is taken away slowly. If it so, is necessary to adjust structure of a mix or to replace a candle.
8. If the nasal part of an insulator of a candle is covered with a black raid, it means that a mix too rich. If the raid black and oily, it testifies to wear of the engine and need of its check and repair. If the nasal part of an insulator is covered with a light brown raid, the structure of a mix is optimum and the engine is in a good condition.
9. The interelectrode gap of a spark plug is of great importance, as at too big or at too small gap the size of a spark that leads to decrease in overall performance of the engine changes. The gap should correspond to technical requirements always.
10. Check of a gap is carried out by a wire template (a photo at the left) or shchupy (a photo on the right).
11. Correction of a gap is carried out by a podgibaniye of a lateral electrode (on a photo – a spark plug with neskolshky lateral electrodes). The central electrode by no means cannot be bent, as it can lead to breakage of an insulator and a candle exit out of operation.
12. For a podgibaniye of a lateral electrode of a candle it is necessary to use the special tool.
13. Before spark plug installation in the engine check, that the carving was pure and all threads of a carving whole.
14. For candle screwing up on some rounds it is possible to use a piece of a rubber hose in which on the one hand to insert an insulator of a candle and, rotating a hose, to wrap a candle on some rounds. Then it is necessary to remove a hose and to screw up a candle the demanded moment.
15. Connect to candles high-voltage wires.
