4-CYLINDER ENGINE
Removal
| PERFORMANCE ORDER |
|
1. Separate shtekkerny connection between the engine and coils of ignition (X26/24). |
| 2. Take and put aside a tank of a stekloomyvatel. |
| 3. Unscrew an arm of the 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 (shooter). 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 a sticky tape and unscrew them. |
7. Extend coils of ignition (T1/1) and (T1/2).
Prevention
Connecting elements are energized to 400 Volts. Therefore always it is necessary to connect clips / package of the core to the car case.
|
|
8. Mount ignition coils in sequence, return to removal. Respectively, one coil of ignition запитывает tension two spark plugs. |

6-CYLINDER ENGINE
Removal
| PERFORMANCE ORDER |
| 1. Remove a cross-section pipe of the air filter, for this purpose weaken shlangovy clips. |
|
2. Unscrew a protective casing of spark plugs (5/1). |
| 3. Remove tips of wires of a chain of management on coils of ignition (shooters). |
|
4. Remove tips of wires of a high voltage on an exit of a secondary chain (Tb). |
Prevention
Coils of ignition (Т1) are got by means of the candle tip through (That) directly on a spark plug. The exit of a secondary chain (Tb) by means of a wire of a high voltage arrives on the corresponding spark plug. The directing pin (W) at the same time is an element of connection of the coil of ignition on the case.
|
5. Pull up the ignition coil.
Prevention
Connections of primary chain are energized to 400 Volts! Therefore always a clip / package of the core should be connected to the car case.

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