Replacing spark plugs
Spark plugs replaced during routine maintenance. If you have to ever replace the spark plug is not in the routine maintenance, you should take the following into consideration. Plugs and plug the whole system as a whole matched to this engine, and it reduces the amount of harmful substances in exhaust gases. To avoid failure in the engine, reducing its capacity, worsening pickup, increasing the content of harmful substances in exhaust gases and the creation of harmful interference to radio should be used only approved Volkswagen spark plug for the engine. Especially important characteristics of candles are the number of electrodes, heat rating and in some cases, the ability to not interfere with the radio. Proper functioning of spark plugs - one of the most important conditions for the effective operation of the engine. It is necessary that on the engine spark plugs were installed only the specified type. With proper cleaning of the engine spark plugs - a rare operation.
Tools required for unscrewing the spark plug and adjust the electrode gap
Engine 1,6-I
Arrangement of screws (1) securing the top casing of the engine 1,6-I
Location tips (2) high-voltage wires to the spark plugs
The engine 1,8-I
Location staples (1) securing the top casing of the engine 1,8-I
Location tips of high-voltage wires on spark ignition engine 1,8-I
Engines 2,3-I (5 cylinders)
Location tips of high-voltage wires on spark ignition engine 2,3-I

| PERFORMANCE ORDER | | 1. Open the hood. | | 2. Label the high-voltage wires in figures and remove the tips of high-voltage wires from spark plugs, see. Fig. Location of tips high-voltage wires on spark ignition engine-I 2,3. | | 3. Clear candles, using a brush, vacuum cleaner or a jet of compressed air that will exclude dirt hit in cylinders of the engine after removing the spark plugs. Unscrew candles using candle key. |

Visual inspection of the working part of spark plugs can reveal the condition of the engine. If the nasal part of an insulator of spark plugs pure and white, without a touch it testifies to too poor mix. It also specifies that the candle too hot, that is warmly from the central electrode is taken away slowly. If so, it is necessary to adjust the composition of the fuel mixture or replace the spark. If the nose of the insulator is covered by black touch, it indicates that the mixture is too rich. If plaque is black and oily, it is a witness exists on engine wear and the need to check and repair. If the nose of the insulator is covered by light brown touch the mix structure is optimum also the engine is in good condition. Spark plug electrode gap is important because if too much and too small a size of a spark gap is changed, resulting in reduced engine performance. The gap must always conform to the specifications.
Measuring the gap of the spark plug wire template
Measure the spark plug gap feeler
Backlash check is carried out by a wire template or probe. The adjustment of the gap is carried podgibaniem side electrode. The central electrode in no case can not be bent, as this may cause damage to the insulator and a candle exit out of operation. For podgibaniem side electrode spark necessary to use a special tool. Before installing a spark plug in the engine, check that the thread was clean and all the threads of the entire thread. Screw in spark plugs by hand and then tighten to torque. Connect the spark plugs high-voltage wires.
