Spark plugs

(Concerning replacement of spark plugs address to 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.

Spark plugs are desirable for clearing the peskostruyny device through each 20 000 km. Thus establish the corresponding interelectrode distance if candles of usual type (with one electrode of weight are applied). At distance adjustment 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 extraneous subjects. Got to openings of candles of a washer, 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 a mix and an engine condition (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 run. At a vvinchivaniye of candles 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.
