ENGINE MAINTENANCE (QR20DE·QR25DE)
4. Apply engine oil to the oil seal circumference of the new oil filter.
5. Screw the oil filter manually until it touches the installation sur-
face, then tighten it by 2/3 turn.
6. After warming up the engine, check for engine oil leakage.
7. Check engine oil level and add engine oil. Refer to LU-7, "
ENGINE OIL" .
Checking and Changing Spark PlugsELS000K1
REMOVAL
1. Remove ignition coil. Refer to EM-29, "IGNITION COIL" .
2. Remove spark plug with suitable spark plug wrench.
CAUTION:
Do not drop or shock it.
INSPECTION AFTER REMOVAL
●Use standard type spark plug for normal condition.
●The hot type spark plug is suitable when fouling occurs with the standard type spark plug under conditions
such as.
–frequent engine starts.
–low ambient temperatures.
●The cold type spark plug is suitable when spark knock occurs with the standard type spark plug under
conditions such as.
–extended highway driving.
–frequent high engine revolution.
