Inspection |
[On vehicle inspection] |
1. |
Accelerate the engine to about 3,000 rpm for 3 minutes or longer. |
2. |
Remove the spark plug. |
3. |
Check the spark plug visually.
If the electrode is dry, the spark plug is normal.
If the electrode is wet, check the damage and electrode gap as below. |
[Component Inspection] |
1. |
Check the spark plug for any damage on its thread and insulator.
If there is damage, replace the spark plug. |
2. |
Check the electrode. Measure the insulation resistance with an ohmmeter.
If the resistance is less than the specified value, adjust the electrode gap.
|
3. |
Check the spark plug electrode gap.
If the gap is greater than the maximum, replace the spark plug.
|
Cleaning |
[1st Method] |
1. |
Start the engine and keep the engine running at idle for 2 minutes. |
2. |
Step on the accelerator pedal and hold it steady at 4500 rpm
with the shift lever in N position to warm up the engine until the
temperature of the engine coolant reaches 80°C. |
3. |
Keep the engine running at 2500~3000 rpm in the N position for 15 minutes. |
[2nd Method] |
|
1. |
Start the engine and keep the engine running at idle for 2 minutes. |
2. |
Drive the vehicle for over 20 minutes, keeping the engine speed above 3500 rpm.
|
