Spark plugs

(Concerning replacement of spark plugs address to materials Check and replacement of spark plugs) Has undressed

Manufacturers recommend candles of certain type, however it is possible to use suitable candles with corresponding калильным number of other manufacturers.

Spark plugs are desirable for clearing пескоструйным the 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 вывинчиванием candles check up, that in niches of candles there were no extraneous subjects. Got to apertures 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 ввинчивании candles watch, that they have not been drawn, as the sealing washer can be damaged. Do not exceed the moment of an inhaling 25 Nm.
