Spark plugs(Concerning replacement of spark plugs address materials of the Section Check and replacement of spark plugs)
Producers recommend candles of a certain type, however it is possible to use suitable candles with the corresponding kalilny number of other producers.
It is desirable to clear spark plugs the sanding device through each 20 000 km. At the same time establish the corresponding interelectrode distance if candles of usual type are applied (with one electrode of weight). At adjustment of distance never turn in an average electrode as the porcelain insulator can burst.
Before a vyvinchivaniye of candles check that in niches of candles there were no foreign objects. The washers which got to openings of candles, bolts or stones will destroy valves, saddles of valves or a head of cylinders at the first start of the engine.
On appearance of a candle it is possible to draw a conclusion on work of candles, work of system of injection, a condition of mix and a condition of the engine (pistons, piston rings, etc.).
As the interval of replacement of candles makes 40 000 km, it is enough to clear of them through each 20 000 km of a run. At a vvinchivaniye of candles you watch that they were not drawn as the sealing washer can be damaged. Do not exceed the moment of an inhaling of 25 N • m.
