ENGINE MAINTENANCE (YD22DDTI)

5. Remove O-ring from oil filter body.

Push O-ring in one direction, lift the slack part using fingers,
and remove O-ring from oil filter body.
CAUTION:
Do not use a screwdrivers etc. as they may cause dam-
age to oil filter body.
INSTALLATION
1. Completely remove all foreign objects adhering to the inside of oil filter body or O-ring mounting area
(body side and bracket side).
2. Install oil filter and O-ring to oil filter body.

Push oil filter into filter body completely.
3. Install oil filter body to oil filter bracket.
INSPECTION AFTER INSTALLATION
1. After warming up engine, check there is no leaks of engine oil.
2. Stop engine and wait for 10 minutes.
3. Check the engine oil level and add engine oil. Refer to MA-33, "
Changing Engine Oil" .
Draining WaterELS000CJ
1. Prepare a tray at the drain hose open end.
2. Loosen drain cock, and operate priming pump to drain water
from fuel filter.
CAUTION:

Water in filter is drained with fuel. Prepare larger capacity
pan than fuel filter volume.

Drained water is mixed with fuel. Prevent fuel from adher-
ing to rubber parts such as engine mount insulator.
3. After draining, close drain cock by hand.
CAUTION:
If drain cock is tightened excessively, it may be damaged
and fuel will leak. Do not use tools to tighten drain cock.
4. Bleed air in fuel piping. Refer to FL-18, "
Air Bleeding" .
5. Start engine and make sure there is no fuel leakage.
