Hyundai Tucson: Ignition System / Spark Plug Repair procedures
| 1. |
Accelerate the engine to about 3,000 rpm 3 times or more. |
| 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. |
| 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.
Specification: 10 Mx or more
|
|
| 3. |
Check the spark plug electrode gap.
If the gap is greater than the maximum, replace the spark plug.
Specification: 1.0 ~ 1.1 mm (0.0394 ~ 0.0433 in.)
|
| • |
If adjusting the gap of a new spark plug, bend only the base of the ground electrode. Do not touch the tip.
Never attempt to adjust the gap on a used plug. |
|
|
The combustion temporarily becomes unstable, due to the aged
fuel and the carbon deposits accumulated on the spark plug(s) after
long-term storage.
| 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. 
|
| • |
The 2nd method should be performed only if the 1st method fails (the misfire-related codes recur).
|
|
| 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.
| • |
If equipped with manual transaxle, shift the gear properly for keeping the engine speed above 3500 rpm. |
|
|
| 1. |
Remove the ignition coil.
(Refer to Ignition System - "Ignition Coil") |
| 2. |
Using a spark plug wrench, remove the spark plug (A).
| • |
Be careful that no contaminates enter into spark plug holes. |
|
|
| 1. |
Install in the reverse order of removal.
Tightening torque:
14.7 ~ 24.5 N.m (1.5 ~ 2.5 kgf.m, 10.8 ~ 18.0 Ib-ft)
