2003 HONDA S2000 coolant level

The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Turn the radiator cap counter-
clockwise, without pressing down
on it, until it stops. This relieves
any pressure remaining in the
cooling system.
Remove the radiator cap by
pushing down and turning
counterclockwise. 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.
Put the radiator cap back on.
Tighten it f ully. Pourthecoolantslowlyand
caref ully so you do not spill. Clean
up any spills immediately. Spilled
coolant could damage components
in the engine compartment. Do not add any rust inhibitors or
other additives to your car’s cooling
system. They may not be compatible
with the coolant or engine compo-
nents.

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 (see page
). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks. Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes
of f .
If there was no coolant in the
reserve tank, you may also have 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.

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.

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.
