ENGINE MAINTENANCE (QR20DE·QR25DE)

3. Screw oil filter manually until it touches the installation surface,
then tighten it by 2/3 turn. Or tighten to specification.
INSPECTION AFTER INSTALLATION
1. Start engine, and make sure there is no leaks of engine oil.
2. Stop engine and wait for 10 minutes.
3. Check the engine oil level and adjust engine oil. Refer to MA-24, "
Changing Engine Oil" .
Checking and Changing Spark PlugsELS000ZK
REMOVAL
1. Remove ignition coil. Refer to EM-31, "IGNITION COIL" .
2. Remove spark plug with spark plug wrench (commercial service
tool).
CAUTION:
Do not drop or shock it.
INSPECTION AFTER REMOVAL (EXCEPT FOR RUSSIA)
Use standard type spark plug for normal condition.
Hot type spark plug is suitable when fouling occurs with standard type spark plug under conditions such as:

Frequent engine starts

Low ambient temperatures
Cold type spark plug is suitable when spark plug knock occurs with standard type spark plug under conditions
such as:

Extended highway driving

Frequent high engine revolution

Check plug gap of each spark plug.

If out of standard, adjust or replace spark plug.

Use a wire brush for cleaning, if necessary.Oil filter:
