RADIATOR
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 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.
lUsecompressedairlowerthan490kPa(5kg/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.Standard

CYLINDER BLOCK
MAIN BEARING HOUSING INNER DIAMETER
lWithout installing main bearings, install main bearing caps, and
tighten bolts to the specified torque.
lMeasure the inner diameter of main bearing housing with a bore
gauge.
lIf the measurement is out of the specified range, replace cylin-
der block and main bearing caps.
PISTON TO CYLINDER BORE CLEARANCE
Cylinder Bore Inner Diameter
lUsing bore gauge, measure cylinder inner diameters at 6 posi-
tions; top, middle, and bottom (A, B, C) in 2 directions (X, Y).
lIf clearance exceeds the limit, or any flaws or seizures are found
on inner surface of cylinder, horn or bore the applicable cylinder
or redore all cylinder.
Piston Outer Diameter
Use micrometer to measure piston skirt outer diameter.
Calculation of Piston to Piston Bore Clearance
lCalculate using piston skirt outer diameter and cylinder inner diameter (direction X, position B).

ENGINE MAINTENANCE (QR20DE)
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 SystemELS000C1
WAR NIN G:
Never remove the radiator cap when the engine is hot; serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around the cap and carefully remove it by turning it a quarter turn to allow built-up
pressure to escape and then turn the cap all the way off.
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 downward.
2. Apply water again to all radiator core surfaces 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 downward.
lUsecompressedairlowerthan490kPa(5kg/cm2, 71 psi) and keep distance more than 30 cm (11.8
in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.
CHECKING RADIATOR CAP
1. Pull the negative pressure valve to open it and check that it
close completely when released.
lCheck that there is no dirt or damage on the valve seat of the
radiator cap negative-pressure valve.
lCheck that there are no abnormalities in the opening and closing
conditions of the negative-pressure valve.
2. Check radiator cap relief pressure.
lWhen connecting the radiator cap to the tester, apply engine
coolant to the cap seal part.
lReplace the radiator cap if there is an abnormality in the nega-
tive-pressure valve, or if the open-valve pressure is outside of
the standard values.

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.

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.
