2004 HONDA S2000 engine coolant

Turn of f the engine and let it sit
f or several minutes, then check
the oil level on the dipstick. If
necessary, add more oil.If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line.
Inspect the cooling system f or leaks. If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda antif reeze/coolant as soon as
possible.
Always use Honda All Season
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 percent
antif reeze and 50 percent water.
Never add straight antifreeze or
plain water.

NOTICE:
RESERVE TANK
MAX MIN
Improper disposal of engine
oil can be harmf ul to the environment.
If you change your own oil, please
dispose of the used oil properly. Put it
in a sealed container, and take it to a
recycling center. Do not discard it in a
trash bin or dump it on the ground.

If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.When the radiator and engine are
cool, relieve any pressure in the
cooling system by turning the
radiator cap counterclockwise,
without pressing down.
Remove the radiator cap by
pushing down and turning
counterclockwise.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Pour the coolant slowly and
caref ully so you do not spill. Clean
up any spill immediately; it could
damage components in the engine
compartment.
Put the radiator cap on, and
tighten it fully.
Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components.

RADIATOR CAP
Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.

Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (seeon page ).
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark. If the temperature gauge stays at
the red mark, turn of f the engine.
If you do not see steam or spray,
leave the engine running, and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge comes down to the midpoint,
then continue driving. If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood. Saf ely pull to the side of the road.
Put the transmission in Neutral,
and set the parking brake. Turn
of f the all accessories, and turn on
the hazard warning indicators.

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.

If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the reading
reaches the middle of the
temperature gauge, or lower,
bef ore checking the radiator.Using gloves or large heavy cloth,
turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.
Start the engine, and set the
temperature control dial to
maximum. Add coolant to the
radiator up to the base of the f iller
neck. If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and ref illed with
the proper mixture as soon as you
can.Put the radiator cap back on
tightly. Run the engine, and watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (see
on page ).
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
