Replacement of spark plugs (every 48 000 km (30,000 miles) or every two years)

Open the hood and label spark plug wires to ensure proper connection of the assembly.

In most cases, the number needed to replace spark plugs tools include candle head is fitted with a soft insert serves to prevent damage to the porcelain insulator candles complete with a ratchet drive and a set of collars and extensions, as well as a tool to measure and adjust the spark plug gap. Furthermore, special tools are available for the safe removal tips of candle wires shank candles, but the use of this tool is not a requirement of the procedure. To tighten new spark needed torque wrench.

Tools required for product replacement spark plugs.

1 - Candle head - equipped with special soft insert, which is used to protect against damage to the porcelain insulator candles
2 - Torque wrench - Although it is not absolutely necessary tool, its use is highly desirable in the implementation of the new tightening of candles with demanded effort
3 - Ratchet drive - is a standard bench tools used to work with replaceable face heads
4 - Extension - Depending on the model and equipment of the vehicle auxiliary units, unscrewing candles may need to use different configuration extension cords equipped with universal joints
5 - tool for measuring and adjusting the clearance of plugs - Available in a wide variety of designs such instruments. Make available the probe required for your car thickness

The best approach to the implementation of this procedure is the maintenance of the car purchase new spark advance. After the adjustment of the spark gaps should be replaced by one (passing to unscrewing the old second after setting a new first, and so on). When buying a new spark pay special attention to their compliance with the specifications of the engine size of your car. Necessary information can be found on the nameplate of information systems reduce emissions vehicle (VECI), located under the hood, in the owner's manual or in the Specifications to this Chapter. When discrepancies preference should always be given to data VECI.

PERFORMANCE ORDER

Before proceeding to the removal of the candles and wait for the complete cooling of the engine. Take the necessary time for this to check the status of new and adjustment of backlashes of candles. Measure the clearance of plugs produced by introducing between the electrodes candles working part of the probe required thickness. The gap should correspond to the data VECI. The probe should slide between the electrodes with only minor resistance. If the gap needs adjusting, use the built-in controller for the meter body podgibaniem side electrode. If the side electrode is not exactly over the central, tweak it using the same controller. Check the surface of the porcelain insulator candles for cracks (in the case of those replace the spark). Producers recommend to use the spark plug electrode gap to measure the probe wire-type - if the probe does not slip between the electrodes with a slight resistance, requires an adjustment of the gap. To adjust the gap bend the side electrode, respectively in one of the directions indicated by the arrows, taking great care not to damage surrounding the center electrode porcelain insulator. After cooling of the engine, remove the wire from the spark plug first. Pull only the tip, and in any case not the cord. It is advisable to use a special tool (see. P. "In most cases ..."). When removing the wire from the spark plug, always pull the tip of his, turning it at the same time. If there is a source of compressed air, use it to blow out the candle niches debris. For this purpose, no worse can come and ordinary bicycle pump. The objective of this procedure is to avoid getting into the cylinder through the spark plug hole after removing the debris candles. Put a candle on the candle head and remove the spark plug from the engine by turning it counterclockwise. Check the condition of the spark when using the card states the spark plugs [to be inserted elsewhere in the Guide]. The external condition of the spark can give important information about the general state of the engine. Screw in one of the prepared new spark into the hole by hand until it stops, then tighten it with a torque wrench (if available) or a ratchet drive. A good idea would be to put a candle in the baiting her tail section of the fuel hose and turn the candle for him. This will avoid damaging the thread in the case of torsion candles when mounted in the hole, since the hose will begin with increasing slip resistance. Before installing the wire tip to tail candles carefully check its condition in accordance with the instructions in Checking the spark plug wires, distributor cap and slider (every 48 000 km (30,000 miles) or every two years). Connect wire to spark a new, re-making the rotational-translational motion of the tip until it is fully seated on the plug. Repeat for the remaining candles, replacing them one by one in order to avoid incorrect wiring.
