Replacing the spark in a car Mazda

Candles - very whimsical element of the car's ignition. At Mazda car, they are designed to work for mileage from 40,000 km to 100,000 km and can be damaged even after a few low-quality fuel vehicle refueling, and also because of sharp drops in temperature and humidity. The need to replace candles indicate difficulties in starting and engine roughness. Replace the spark plugs themselves can even novice motorist amateur. This procedure will need: a candle key (a hexagon on a tubular design), if no, then handpicked ratchet or screwdriver, wrench 8 mm, a device for checking the interelectrode gap and, in fact, themselves the candles in the quantity of 4 pieces, which should be of a type specified in the instructions to the vehicle Mazda. Work on replacing the candles should be done only after complete cooling the engine. Consider a phased replacement of one spark plug. 1.Otkryv hood, you should remove the plastic trim by pulling it from both sides up. 2.Vo prevent dust, sand and dirt in the motor, clean the space around them to spark a stream of air from high pressure compressor, or with a brush. 3.Otsoedinit high-voltage wires and remove the cap with them from prison candle: for this it must swing to the right and left, and then gently pull upwards. 4.Slegka pressing, candle-key unscrew the spark plug, making 12 turns counterclockwise. 5.Vytyanut candle with a key block from the head. 6.You remove candle, it must be thoroughly inspected and thereby ensure its normal operation. The candle should be light brown in color with no traces of soot, the electrodes on it should not be burnt on the threaded portion should be oily residue. If it finds the candle dry black soot, so it's a sign that the engine works a lot at low speeds or idle. Wet black smoke indicates too high a level of engine oil in the crankcase, or wear on piston rings and cylinder engine. Oily candle speaks of maslootrazhatelnyh wear caps, which causes misfiring and difficult start of the engine. 7.Ubeditsya in the right amount of clearance between the lateral and central electrodes candles (this is done through the introduction of a special probe measuring device) and, if necessary, set the correct distance by podgibaniya side electrode. 8.Proteret thread the new spark a clean dry cloth and rub anti-corrosion compound. 9.Opustit candle in the candle hole electrode down and twist clockwise, using a spark plug wrench. Making sure that the candle is not skewed in the thread, tighten until it stops. 10.Plotno wear a cap on high-voltage wire insulator candles. Similarly, there is a replacement of spark plugs at the other three cylinders. Sometimes, instead of replacing the spark can do them a thorough cleaning. However, one should remember that this can not do metal objects (such as a screwdriver or a knife) as well as possible damage to the facility.
