7.3. Ignition coils



1. Separate штеккерное connection between the engine and ignition coils (X26/24).
2. Take and put aside a tank стеклоомывателя.
3. Unscrew an arm of an inlet gas pipeline.
4. If is available, uncouple the lever mechanism темпомата.
5. Remove from coils of ignition of a wire of a high voltage (marksman). Turn out bolts (20/1) to ignition coils.
6. Open protective caps (20/2) on the bottom party of coils of ignition. Note wires on plugs 15 and 1 sticky tape and unscrew them.
7. Extend ignition coils (Т1/1) and (Т1/2).
The prevention

Connecting elements are energised to 400 Volt. Therefore always it is necessary to connect clips / a core package to the car case.

8. Mount ignition coils in sequence, return to removal. Accordingly, one coil of ignition запитывает pressure two spark plugs.



1. Remove a cross-section pipe of the air filter, for this purpose ослабьте шланговые clips.
2. Unscrew a protective casing of spark plugs (5/1).
3. Remove штеккеры wires of a chain of management on coils of ignition (arrow).
4. Remove штеккеры high voltage wires on an exit of a secondary chain (Tb).

The prevention

Ignition coils (Т1) насажены by means of candle штеккера through (That) it is direct on a spark plug. The exit of a secondary chain (Tb) by means of a high voltage wire arrives on a corresponding spark plug. The directing pin (W) simultaneously is an element of connection of the coil of ignition on the case.

5. Pull upwards the ignition coil.
The prevention

Connections of a primary chain are energised to 400 Volt! Therefore always a clip / a core package should be connected to the car case.


Installation is made in sequence, return to removal. In drawing the scheme of connection of coils of ignition and spark plugs is presented. Accordingly, one coil of ignition запитывает a high voltage two spark plugs.
