Replacement of spark plugs / check the electrical contacts
It takes a special tool: - Candlestick key.
- Additionally, it is recommended to buy a special tongs, for example, HAZET 1849 to facilitate the removal of the spark.
Must be purchased the following parts: Withdrawal | - Disconnect all the spark, thus it is necessary to pull the plug, not the cord. The above facilitate the removal of the forceps.
- Blow out the candles niche compressed air that, when taken in candlelight holes could be dirty.
- Remove the spark plug wrench, and check the status of candles (appearance). With some experience you can from this draw conclusions about the state of the engine:
|
|
Electrodes and insulators Average gray - the correct operation of the Sich ignition quality of the mixture Black - mixture too rich Light gray - is too lean Zamasleny - disruptions in the corresponding candle or poor insulation of piston rings (check compression). | - Check insulators candles on the surface leakage currents. Surface currents are left on the surface of a thin, uneven tracks. You may need to replace leaking tips candles.
|
|
Setting |  | - Before installation, check the distance between the electrodes by a feeler gauge.
|
- In new spark distance between the electrodes, as a rule, is installed correctly. See Chapter Ignition system, Section Candles for your MAZDA 323.
 | - To adjust the distance between the contacts must bend the electrode mass. For this purpose there is a simple, practical adaptation, otherwise knock on the electrode mass. When podgibaniem rest against a small screwdriver into the thread of candles, in any case not in the center electrode, as otherwise it will be damaged.
|
- Clean the threads on the plugs with a clean cloth.
- Screw in the spark plug by hand until it is tight to the cylinder head.
 | Candles with no skew. |
- Tighten the spark plug with a torque of 20 Nm.
| If there is no torque wrench, tighten the new spark plugs spark plug wrench by 90 ?� (1/4 turn). Used to tighten the spark only at 15 ?�. If tightened too much when unscrewing the spark may break or damage the threads in the cylinder head. In this case, repair the thread repair inserts UTC or Heli - Coil. |
- Connect the spark plug according to the order 1-3-4-2.
- Check tightness of cables and the spark plugs.
|
|
Check electrical connectors | - Check tightness of all electrical connections to the ignition coil.
- Cracked terminals replaced.
- Clean the corroded contacts with a wire brush or sandpaper, if necessary, spray the spray contacts.
- Contacts should not be wet, otherwise clean contact and spray spray contacts.
- Bend the ignition cables to check for cracks. If necessary, replace the cables plug.
