2000 HONDA ODYSSEY coolant temperature

Gauges
Trip Mete r
This meter shows the number of
miles (U.S.) or kilometers (Canada)driven since you last reset it.
There are two trip meters: Trip A and Trip B. Switch between these
displays by pressing the Select/
Reset button repeatedly. Each trip
meter works independently, so you can keep track of two different
distances.
To reset a trip meter, display it and then press and hold the Select/Reset
button until the number resets to
"0.0".
Temperatur e Gaug e
This shows the temperature of the engine's coolant. During normal
operation, the pointer should rise
from the bottom white mark to about the middle of the gauge. In severedriving conditions, such as very hot
weather or a long period of uphill driving, the pointer may rise to near
the upper white mark. If it reaches
the red (Hot) mark, pull safely to the side of the road. Turn to page 305 for
instructions and precautions on checking the engine's cooling
system.
Fue l Gaug e
This shows how much fuel you have. It is most accurate when the vehicle
is on level ground. It may showslightly more or less than the actual
amount when you are driving on
curvy or hilly roads.
The needle returns to the bottom after you turn off the ignition. The
gauge shows the fuel level reading
immediately after you turn the
ignition switch back ON (II).

How to Us e th e Syste m
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.
It is best to leave the system in Fresh
Air mode under almost all conditions. Keeping the system in Recirculation
mode, particularly with the A/C off,
can cause the windows to fog up.
Switch to Recirculation mode when
you are driving through smoky or dusty conditions, then switch back to
Fresh Air mode when the conditionFA N CONTRO LDIALMOD E BUTTON STEMPERATUR ECONTROL DIA L

clears.
The outside air intakes for the
heating and cooling system are atthe base of the windshield. Keep
these clear of leaves and other
debris.
Ventilation
The flow-through ventilation system draws in outside air, circulates it
through the interior, then exhausts it
through vents near the rear side
panels.
1. Turn the temperature control dial all the way to the left.
Make sure the A/C is off.
2. Select and Fresh Air mode.
3. Set the fan to the desired speed.

To Cool with A/C

button. The light above 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.

4. If the outside air is humid, selectRecirculation mode. If the outside
air is dry, select Fresh Air mode.
5. 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 turned all the
way to the left.
3. Set the fan to maximum speed.
4. Open the windows partially. Select

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 63 ) when driving in stop-and-go
traffic or climbing a long, steep hill. If it moves near the red zone, turn
off the A/C until the gauge reads
normally.

These settings direct all the air flow
to the defroster vents at the base of
the windshield and the side windowdefroster vents. The air flow will get
warmer and clear the windows faster as the engine warms up. You canclose the corner vents with the dial
beside each vent. This will send more warm air to the windshield
defroster vents.
For safety, make sure you have a
clear view through all the windows
before driving away.T o Tur n Everythin g Of f
To shut off the system temporarily,
turn the fan speed and temperaturecontrol dials all the way to the left.
You should shut the system completely off only for the first few
minutes of driving in cold weather,
until the engine coolant warms up
enough to operate the heater. Keep
the fan on at all other times so stale air does not build up in the interior.

Cooling Syste m
Replacin g Engin e Coolan t
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 controldial fully clockwise. Turn the
ignition off.
Open the hood. Make sure the
engine and radiator are cool to the
touch.
2. Remove the radiator cap. 3. Loosen the drain plug on the
bottom of the radiator. Thecoolant will drain through thesplash guard. Loosen the drain
bolt.

If You r Engin e Overheat s
The pointer of your vehicle'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.
Driving with the temperature gauge
pointer at the red mark can cause serious damage to your engine.
Your vehicle 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 hood.
In either case, you should take
immediate action.
1. Safely pull to the side of the road. Put the transmission in Neutral or
Park and set the parking brake.
Turn off the heating and cooling/ climate control system and allother accessories. Turn on the
hazard warning indicators.
2. If you see steam and/or spray coming from under the hood, turnoff the engine.
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.

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

If You r Engin e Overheat s
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.
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 Emergenc y
Towin g on page 317).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page 193). 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 toadd coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, before check-
ing 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. 10. Start the engine and set the
temperature control dial to
maximum (climate control to
FULL AUTO at 90°F/32°C). 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 assoon as you can.
11. 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 Emergenc y
Towin g on page 317.)
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.
Takin g Car e o f th e Unexpecte d
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.
