THE 4-CYLINDER ENGINE
Removal
| PERFORMANCE ORDER |
|
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. |

THE 6-CYLINDER ENGINE
Removal
| PERFORMANCE ORDER |
| 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.
