10. Warm up engine, and check for sound of coolant flow while running engine from idle up to 3,000 rpm with
heater temperature controller set at several position between COOL and WARM.
lSound may be noticeable at heater unit.
11. If sound is heard, bleed air from cooling system by repeating steps 5 through 7 until coolant level no
longer drops.
lClean excess coolant from engine.
FLUSHING COOLING SYSTEM
1. Fill radiator with water until water spills from the air relief hole, then close air relief flag. Fill radiator and
reservoir tank with water and reinstall radiator cap.
2. Run engine and warm it up to normal operating temperature.
3. Rev engine two or three times under no-load.
4. Stop engine and wait until it cools down.
5. Drain water.
6. Repeat steps 1 through 5 until clear water begins to drain from radiator.
Checking Cooling SystemELS000C4
WA RN ING:
Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure
coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter turn to
allow built-up pressure to escape. Carefully remove the cap by turning it all the way.
CHECKING COOLING SYSTEM HOSES
Check hoses for improper attachment, leaks, cracks, damage, loose connections, chafing and deterioration.
CHECKING RADIATOR
Check radiator for mud or clogging. If necessary, clean radiator as follows.
lBe careful not to bend or damage the radiator fins.
lWhen radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator
shroud and horns. Then tape the harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downwards.
2. Apply water again to all radiator core surface once per minute.
3. Stop washing if any stains no longer flow out from the radiator.
4. Blow air into the back side of radiator core vertically downwards.
lUse compressed air lower than 490 kpa (5 kg/cm2, 71psi) and keep distance more than 30 cm(11.8 in).
5. Blow air again into all the radiator core surface once per minute until no water sprays out.
CHECKING RADIATOR CAP
lCheck that there is no dirt or damage on the valve seat of the radiator cap negative-pressure valve.
lCheck that there are no unusualness in the opening and closing
conditions of the negative-pressure valve.
lPull the negative pressure valve to open it.
lCheck that it close completely when released.

ENGINE MAINTENANCE (YD22DDTI)
lCheck radiator cap relief pressure.
lWhen connecting the radiator cap to the tester, apply water or
LLC to the cap seal part.
lReplace the radiator cap if there is an unusualness in the nega-
tive-pressure valve, or if the open-valve pressure is outside of
the standard values.
CHECKING COOLING SYSTEM FOR LEAKS
lTo check for leakage, apply pressure to the cooling system with
atester.
WAR NIN G:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
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.

Changing Engine Oil
ELS000CH
WAR NIN G:
lBe careful not to burn yourself, as the engine oil is hot.
lProlonged and repeated contact with used engine oil may
cause skin cancer: try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with soap
or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine compo-
nents.
2. Stop engine and wait for 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain oil and refill with new engine oil.
Oil specification and viscosity:
lAPI grade CF-4.
lRefer toMA-17, "RECOMMENDED FLUIDS AND LUBRI-
CANTS".
Oil capcity (Approximate):
lThe refill capacity depends on the oil temperature and drain time. Use these specifications for reference
only.
Always use the dipstick to the determine when the proper amount of oil is in the engine.
CAUTION:
lBe sure to clean drain plug and install with new washer.
lThe refill capacity depends on the oil temperature and drain time. Use these specifications for ref-
erence only.

5. Warm up engine and check area around drain plug and oil filter for oil leakage.
6. Stop engine and wait for 10 minutes.
7. Check oil level.

loosen the filter body approximately four turns.
2. Drain the oil after matching the "DRAIN" arrow mark at the bot-
tom of the filter body to the protrusion on the oil filter bracket.
lCatch the oil with a pan or cloth.
CAUTION:
lThe drained oil flows over the right surface of the filter
body.
lCompletely wipe clean any engine oil remaining on the
filter body or vehicle.

lCoolant in filter is drained with fuel. Prepare larger capacity
pan than fuel filter volum.
lDrained coolant 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
