1. On models 1.8 and 2.0 litres for access to spark plugs are necessary to remove the coil of ignition fixed in the centre of a casing of a cover of a head of the block of cylinders. Remove an electric socket (it is specified by an arrow) on the left side of the coil of ignition and unscrew 6 bolts of fastening. Remove the ignition coil upwards and unscrew candles. |
| 2. On some models for access to spark plugs it is necessary to remove air branch pipes. |
| 3. On models of engines in volume of 1.6 litres in the absence of labels on high-voltage wires it is necessary to mark them not to be mistaken at their further installation. |
| 4. To clear candles, using a brush, a vacuum cleaner or a stream of compressed air that will exclude dirt hit in cylinders of the engine after вывинчивания spark plugs. |
| 5. Unscrew candles, using a candle key (fig. Tools for removal of spark plugs and regulation of a spark backlash see). |
6. The visual control of a working part of a spark plug can show an engine condition. If the nasal part of an insulator of a spark plug pure and white, without a touch, it testifies to too poor mix. It also specifies that the candle too hot, i.e. warmly from the central electrode is taken away slowly.
If it so it is necessary to adjust structure of a mix or to replace a candle. |
| 7. If the nasal part of an insulator of a candle is covered by black touch, it means that a mix too rich. If a touch black and oily it testifies to deterioration of the engine and necessity of its check and repair. |
| 8. If the nasal part of an insulator is covered by light brown touch the mix structure is optimum also the engine is in a good condition. |
|
9. The interelectrode backlash of a spark plug is of great importance, since at too big or too small backlash the size of a spark that leads to decrease in an overall performance of the engine changes. The backlash should correspond to technical requirements always. |
|
10. Backlash check is carried out by a wire template or щупом. Backlash updating is carried out подгибанием a lateral electrode. The central electrode in no event cannot be bent, since it can lead to breakage of an insulator and a candle exit out of operation. |
| 11. Before spark plug installation in the engine check up, that the carving was pure and all threads of a carving whole. Before candle installation in the engine it is possible to grease a carving part of a candle special медьсодержащим антипригарным with structure. |
| 12. For candle screwing up on some coils 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 coils. Then it is necessary to remove a rubber hose and to screw up a candle the demanded moment. |
| 13. On models with working volume of the engine 1.8 and 2.0 litres establish on candles of the coil of ignition, fix their bolts and connect electric sockets. |
| 14. On engines with working volume 1.6. Litre establish high-voltage wires according to marks and all earlier removed elements interfering access to candles. |
