CHECKING RADIATOR SYSTEM FOR LEAKS

To check for leakage, apply pressure to the cooling system with
a radiator cap tester (commercial service tool) and a radiator
cap tester adapter (special service tool).
WARNING:
Do not remove radiator cap when engine is hot. Serious burns
could occur from high-pressure engine coolant escaping from
radiator.
CAUTION:
Higher test pressure than specified may cause radiator damage.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.

If anything is found, repair or replace damaged parts.
Checking Fuel LinesELS000ZG
Inspect fuel lines, filler cap and tank for improper attachment, leaks,
cracks, damage, loose connections, chafing or deterioration. If nec-
essary, repair or replace damaged parts.
Changing Air Cleaner FilterELS000ZH
VISCOUS PAPER TYPE
The viscous paper type filter does not need cleaning.
Changing Engine OilELS000ZI
WARNING:

Be careful not to burn yourself, as engine oil may be hot.

Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct
skin contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
1. Warm up engine, put vehicle horizontally and check for oil leakage from engine components. Refer to LU-
7, "ENGINE OIL LEAKAGE" .
2. Stop engine and wait for 10 minutes.Testing pressure:

2. Check radiator cap relief pressure.

When connecting radiator cap to radiator cap tester (commer-
cial service tool) and radiator cap tester adapter (special ser-
vice tool), apply engine coolant to the cap seal surface.

Replace radiator cap if there is an unusualness in negative-
pressure valve, or if the relief pressure exceed the limit.
CHECKING RADIATOR SYSTEM FOR LEAKS

To check for leaks, apply pressure to the cooling system with
radiator cap tester (commercial service tool) and radiator cap
tester adapter (special service tool).
WARNING:
Never remove the radiator cap when the engine is hot. Seri-
ous burns could occur from high pressure engine coolant
escaping from the radiator.
CAUTION:
Higher test pressure than specified may cause radiator
damage.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.

If anything is found, repair or replace damaged parts.
Checking Fuel LinesELS000CE
Inspect fuel lines, filler cap and tank for improper attachment, leaks,
cracks, damage, loose connections, chafing or deterioration.
If necessary, repair or replace faulty parts.

REMOVAL
1. Remove air duct, air cleaner case and mass air flow sensor assembly. Refer to EM-133, "AIR CLEANER
AND AIR DUCT" .
2. Remove fuel filter protector.
3. Remove fuel hoses from fuel filter bracket.
CAUTION:
Plug the pipe to prevent fuel from draining.
4. Remove fuel filter with fuel filter bracket.
CAUTION:
Do not splash fuel during removal. If fuel is splashed,
immediately wipe it off.
5. Using band-type fuel filter wrench (commercial service tool),
remove fuel filter.
6. Turn fuel filter upside down to drain fuel.
7. Remove drain plug from fuel filter.
INSTALLATION
Install in reverse order of removal, paying attention to following:

Replace O-ring on drain plug with new one.

Screw the fuel filter by hand until packing contacts sealing surface of bracket. Then tighten it by turning
approximately 2/3 turn.

After installation, bleed air from fuel path. Refer to FL-18, "Air Bleeding" .
INSPECTION AFTER INSTALLATION
Make sure there is no fuel leakage at connections in the following steps.

Start the engine and rev it up and check for fuel leaks at connections.

VISCOUS PAPER TYPE
The viscous paper type air cleaner filter does not require any clean-
ing operation between renewal.

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.
