Replacement of spark plugs (each 48 000 km (30 000 miles) of a run, or time in two years)

Open a cowl and mark candle wires for a guarantee of their correct connection at assembly.

In most cases the number of spark plugs of tools, necessary for replacement, includes the candle head equipped with a soft insert of the employee for prevention of damage of the porcelain insulator of a candle complete with the ratchet drive and a set of collars and extenders and also the tool for measurement and adjustment of candle gaps. Besides, special tools for safe removal of tips of candle wires from shafts of candles are issued, however use of this tool is not an indispensable condition of implementation of the procedure. The dynamometer key is necessary for tightening of new candles.

Tools necessary for performing replacement of spark plugs.

1 — the Candle head - Is equipped with the special soft insert serving for protection against damage of the porcelain insulator of a candle
2 — the Dynamometer key - Though is not absolutely necessary tool, its use extremely is desirable at implementation of tightening of new candles with the required effort
3 — the Ratchet drive - Represents the standard metalwork tool used to work with replaceable face heads
4 — the Extender - Depending on model and the equipment of the car auxiliary units, can be necessary for a vyvinchivaniye of candles application of various configuration of the extenders equipped with cardan hinges
5 — the Tool for measurement and adjustment of candle gaps - Is issued a wide range of a various design of such tools. Make sure available the probe of thickness demanded for your car

The best approach to implementation of this procedure of service of the car is acquisition of new candles beforehand. After implementation of adjustment of gaps of a candle it is necessary to replace on one (passing to a vyvinchivaniye old with the second after installation new the first, etc.). Upon purchase of new candles pay special attention to compliance of their standard size to technical characteristics of the engine of your car. Necessary information can be found on information Schild of systems of decrease in the toxicity of the fulfilled gases of the car (VECI) located under a cowl in the operation manual on the car or in Specifications to this Chapter. At discrepancies preference always should be given to data of VECI.

 PERFORMANCE ORDER

  1. Before starting removal of candles, wait for full cooling of the engine. Use time necessary for this purpose for check of a state and adjustment of gaps of new candles.
  2. Measurement of a candle gap is performed by introduction between electrodes of a candle of a working part of the probe of the required thickness. The size of a gap has to correspond to data of VECI. The probe has to slip between electrodes only with an insignificant resistance. If the gap demands adjustment, use the regulator which is built in in a measuring instrument body for a podgibaniye of a side electrode. If the side electrode is located not precisely over central, correct it by means of the same regulator. Check the surface of the porcelain insulator of a candle for existence of cracks (in case of detection of those replace a candle).
  1. Manufacturers of spark plugs recommend to use the probe of wire type for measurement of an interelectrode gap - if the probe does not slip between electrodes with an easy resistance, carrying out adjustment of a gap is required.
  1. For adjustment of a gap turn in a side electrode respectively in one of the directions specified by shooters, working extremely carefully not to damage the porcelain insulator surrounding the central electrode.
  1. After cooling of the engine remove a wire from the first spark plug. Pull only for a tip, and not for a wire at all. It is desirable to use the special tool (see the item. "In most cases"...).
  1. At removal of a wire from a spark plug pull only for its tip, turning it at the same time.
  1. If there is a source of compressed air, use it for blowing from a candle niche of foreign particles. The ordinary bicycle pump can be suitable for this purpose also not worse. A problem of this procedure is not to allow hit in the cylinder through a candle opening of garbage after removal of a candle.
  2. Put on a candle head a candle and unscrew a candle from the engine, rotating it counterclockwise.
  3. Check a condition of a candle at the help of the card of conditions of spark plugs [it has to be inserted somewhere into the Management]. The external condition of a candle can give important information about about the general condition of the engine.
  4. Screw one of the prepared new candles in an opening by hand against the stop, then tighten it by means of a dynamometer key (if that is available) or the ratchet drive. The good idea will be at nazhivleniye of a candle to put on a piece of a fuel hose its shaft and to rotate a candle for it. It will allow to avoid damage of a carving in case of a candle perekashivaniye at installation it in an opening as the hose at increase of resistance will begin to slip.
  5. Before installation of a tip of a wire check for a shaft of a candle carefully its state according to instructions of the Section Check of a Condition of Candle Wires, a cover and the runner of the distributor (each 48 000 km (30 000 miles) of a run, or time in two years).
  6. Connect a wire to a new candle, again making rotary progress by a tip before full landing it on a candle.
  7. Repeat the procedure for the remained candles, replacing them serially in order to avoid the wrong connection of wires.
