Removal and installation of spark plugs
Attention. Using non-recommended spark plugs will reduce engine performance. When replacing, use only recommended spark plugs.
Note: Type of spark plugs: PE01-18-110, PE02-18-110.
1. Disconnect the negative battery terminal.
2. Remove the decorative engine cover.
3. Remove the ignition coils with ion sensors.
4. Remove the spark plugs with a spark plug wrench.
5. Installation is made in an order, the return to removal.
Note: Spark plug torque: 15-20 Nm.
Checking spark plugs
Attention.
- To prevent possible damage to the tip, do not adjust the gap in the spark plug electrodes.
- Use a round deformable feeler gauge to measure spark plug gap.
1. Measure the spark plug gap with a round, deformable feeler gauge. If the measured value is not correct (0.75-1.10mm), replace the spark plug with a new one.
2. Visually check the following:
- Insulator damage.
- Wear of the electrode.
- Gasket damage.
- Burning insulator (from the side of the electrodes).
If any defects are found, replace the spark plug with a new one.
3. Using a tester, measure the resistance of the spark plug as shown in the figure. If the measurement is not correct, replace the spark plug with a new one.
Note: Spark plug resistance (at 25°C): 3.0-7.5 kΩ
Cleaning spark plugs
Attention.
- Carbon deposits on the tip of a spark plug can form when the car travels short distances in winter. In the event of problems such as unstable engine idling or difficult starting due to carbon deposits on the spark plug, you can clean the spark plug by accelerating the engine to high speeds without load.
- To accelerate the engine to high speeds, it is necessary to apply the parking brake and move the gear lever to the neutral position (ITUC) or selector lever to position P (AKP) to prevent an accident and serious injury.
- To prevent possible damage to the spark plug tip, do not use a steel bristle brush for cleaning.
Note:
- To prevent possible damage to the spark plug tip, use gasoline to clean spark plugs after removing dirt.
- If the accelerator pedal is continuously depressed for a certain amount of time, the engine speed may drop to idle. This is due to the fuel cut control function to prevent engine overheating and is not a malfunction. The engine speed is restored to normal when the accelerator pedal is released.
- Do not accelerate the engine to a high engine speed for more than 10 seconds.
If there is carbon deposits on the spark plugs, accelerate the engine to 4000 rpm twice within two minutes.
