The prevention

Do not serve a spark plug on the hot engine.

1. Disconnect a wire from the negative plug of the storage battery.
2. Disconnect high-voltage wires.
3. Compressed air clear candles that will exclude dirt hit in cylinders of the engine after вывинчивания spark plugs.
4. Turn out a candle, using a candle key. For an exception of damage of a candle establish a candle key strictly along a candle axis.


1. Connect a wire to the negative plug of the storage battery.
2. Connect a spark plug to a high-voltage wire.
3. Keeping a spark plug special пассатижами with the isolated handles, bring a spark plug on distance of 5-10 mm to a car body.

The prevention

Do not concern bodies of the car during performance of following operations.

4. The assistant should turn a cranked shaft of the engine a starter, thus between a spark plug and a car body should be observed steady strong искрообразование.

5. In the absence of a spark of ignition or an ignition spark weak, check up a condition and correct following defects:

    – In the presence of a deposit clear or replace a spark plug;
    – At pollution by oil clear or replace a spark plug;
    – At deterioration or burning out of electrodes replace a spark plug;
    – At destruction of a ceramic insulator replace a spark plug;
    – At damage of a ring of a spark plug replace a spark plug;
    – At infringement of an interelectrode backlash in a spark plug, adjust a backlash. Backlash updating is carried out подгибанием a lateral electrode.

The central electrode in no event cannot be bent, as it can lead to breakage of an insulator and a candle exit out of operation. For подгибания a lateral electrode of a candle it is necessary to use the special tool.

Interelectrode backlash of a spark plug:
А3Е: 0,8–0,9 mm
А5D: 0,7–0,8 mm


1. Screw a spark plug in a head of the block of cylinders.

The inhaling moment: 25–30 Nm

2. Connect a high-voltage wire to a spark plug.
3. Connect a wire to the negative plug of the storage battery.
