2000 HONDA S2000 coolant level

Cooling System
2. Turn the radiator cap counter­
clockwise, without pressing down
on it, until it stops.
This relieves
any pressure remaining in the
cooling system.
3. Remove the radiator cap by
pushing down and turning
counterclockwise.
162 Maintenance
4. The coolant level should be up to
the base of the filler neck. Add
coolant
if it is low.
5. Put the radiator cap back on.
Tighten it fully.
6. Pour coolant into the reserve tank.
Fill it to halfway 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.

14.Remove the radiator cap.
15.Pour coolant into the radiator up
to the base of the filler neck and
into the reserve tank up to the
MAX mark.
16.Start
the engine and hold it at
1,500 rpm until the radiator fan
comes on.
Turn off the engine.
Check the coolant level in the
radiator and add coolant
if needed.
17.Install the radiator cap, and
tighten it fully.
18.If necessary, fill the reserve tank

Maintenance

If Your Engine Overheats
6. Look for any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution.
If you find a leak, it
must be repaired before you
continue driving (see
Emergency
Towing on page 238 ) .
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.
224 Taking Care of the Unexpected
7. If you don't find an obvious leak,
check the coolant level in
the
radiator reserve tank (see page
120 ) . If the level is below the
MIN mark, add coolant to halfway
between the MIN and
MAX marks.
8. 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,
before checking the radiator.
9. Using gloves or a large heavy
cloth, turn
the radiator cap
counterclockwise, without pushing
down, to
the first 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
off.

lO.Start the engine and set the
temperature control dial to
maximum. Add coolant to the
radiator up to the base of the filler
neck.
If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and refilled with
the proper mixture as soon as you
can.
ll.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
Emergency
Towing on page 238 .)
If Your Engine Overheats
12.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.
