coolant temperature HONDA S2000 2000 1.G Owners Manual

Liquid crystal is used in the meter
panel. You may feel the indicators
appear slowly
in the low temperature.
Speedometer
This shows your speed in miles per
hour (mph) or kilometers per hour
(km/h). Select
Button
The Select button switches the
speedometer reading between miles
per hour and kilometer per hour.
It
also changes the odometer and trip
meters to read in miles or kilometers
correspondingly. To change the
readings, push the Select button and
hold it until you
hear a beep.
Gauges
Tachometer
The tachometer shows the engine
speed
in revolutions per minute
(rpm). To protect the engine from
damage, never drive with the
tachometer reading in the red zone.
Temperature Gauge
This shows the temperature of the
engine's coolant. During normal
operation, the reading should be
in
the middle of the gauge. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the reading may reach near
the red mark.
If it reaches the red
mark, pull safely to the side of the
road.
Turn to page 223 for
instructions and precautions on
checking
the engine's cooling
system.
Instruments and Controls 4 7

Heating and Cooling
Vent Controls
You can adjust the direction of the
air coming from the vents on both
sides of the instrument panel and at
the corner of the dashboard on the
passenger's side.
To adjust the air
flow up and down, move the tab
in
the center of each vent up and down.
To adjust it left and right, turn the
dial under each vent left and right.
88 Comfort and Convenience Features
You can shut off the air flow from
each vent by turning the dial
all the
way toward the
t>UO mark until it
clicks. How
to Use the System
This
section covers how to set up the
system controls for ventilation,
heating, cooling, dehumidifying, and
defrosting.
The engine must be running for the
heater and air conditioning to
generate hot and cold air.
The heater
uses engine coolant to warm the air.
If the engine is cold, it will be several
minutes before you feel warm air
coming from the system.
The air conditioning does not rely on
engine temperature.

Heating and Cooling
To Cool with A/C
1. Turn on the AI C by pressing the
button.
The light in the button
should come on when a fan speed
is selected.
2. Make sure the temperature
control dial is
all the way to the left.
3. Select ;,; .
4. If the outside air is humid, select
Recirculation mode.
If the outside
air is dry, select Fresh Air mode.
Set
the fan to the desired speed.
If the interior is very warm from
being parked
in the sun, you can cool
it down more rapidly by setting up
the controls this way:
1. Start the engine.
2. Turn on the A/C by pressing the
button. Make sure the tempera­
ture control dial is
all the way to
the left.
3. Set the fan to maximum speed.
4. Open the windows partially. Select
;,; and Recirculation mode.
90 Comfort and Convenience Features
When the interior has cooled down
to a more comfortable temperature,
close the windows and set the
controls as described for normal
cooling. Air
conditioning places an extra load
on the engine. Watch the engine
coolant temperature gauge (see page
47) when driving in stop-and-go
traffic or climbing a long, steep hill.
If it moves near the red mark, turn
off the
A/ C until the reading returns
to normal.

Maintenance 151

Replacing Engine Coolant
The cooling system should be
completely drained and refilled with
new coolant according to
the time
and distance recommendations in
the maintenance schedule. Only use
Genuine Honda Antifreeze/Coolant.
Draining the coolant requires access
to
the underside of the vehicle.
Unless you have the tools and
knowledge, you should have this
maintenance done by a skilled
mechanic.
1. Turn the ignition ON (II). Turn
the heater temperature control
dial fully clockwise.
Turn the
ignition off.
2. Open the hood. Make sure the
engine and radiator are cool to the
touch.
3. Remove the radiator cap.
Cooling System
4. Loosen the drain plug on the
bottom of the radiator. The
coolant will drain through the
splash guard. Remove the drain
bolt and washer from the engine
block.

Maintenance 163

The reading on your car's
temperature gauge should stay in
the midrange under most conditions.
It may go higher if you are driving up
a long steep hill on a very
hot day. If
it climbs to the red mark, you should
determine
the reason.
NOTICE
Driving with the temperature gauge
reading
at the red mark can cause
serious damage to your engine.
Your car can overheat for several
reasons,
such as lack of coolant or a
mechanical problem.
The only
indication may be
the temperature
gauge climbing to or above
the red
mark. Or you may see steam or
spray coming from
under the car or
engine cover. In either case, you
should take immediate action.
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
1. Safely pull to the side of the road.
Put the transmission in Neutral
and
set the parking brake. Turn
off the heating and cooling system
and all
other accessories. Turn on
the hazard warning indicators.
2. If you see steam and/ or spray
coming from
under the hood, turn
off
the engine.
If Your Engine Overheats
3. 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
(climbing a long, steep hill on a
hot day with
the A/C running, for
example),
the engine should start
to cool down almost immediately.
If it does, wait until the tempera­
ture gauge comes down to
the mid­
point
then continue driving.
4. If the temperature gauge stays at
the red mark, turn off the engine.
5. Wait until you see no more signs
of
steam or spray, then open the
hood.

Taking Care of the Unexpected 223

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.
