1999 HONDA ODYSSEY coolant temperature

Gauges

Trip Meter
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".
Temperature Gauge
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 severe driving 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 299 for
instructions and precautions on
checking the engine's cooling
system.
Fuel Gauge

This shows how much fuel you have. It is most accurate when the vehicle
is on level ground. It may show slightly 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 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.
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 condition

clears.

The outside air intakes for the heating and cooling system are at
the 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

should come on when a fan speed
is selected.

4. If the outside air is humid, select
Recirculation 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 all the way to
the left.
3. Set the fan to maximum speed.

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.

Heating and Cooling

These settings direct all the air flow to the defroster vents at the base ofthe windshield and the side windowdefroster vents. The air flow will get
warmer and clear the windows faster as the engine warms up. You can
close 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. To Turn Everything Off
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 System

Replacing Engine Coolant
The cooling system should be completely drained and refilled with
new coolant according to the timeand 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 Your Engine Overheats

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 all
other accessories. Turn on the
hazard warning indicators.
2. If you see steam and/or spray coining 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.

Taking Care of the Unexpected

NOTICE

Steam and spray from an

overheated engine can
seriously scald you.

Do not open the hood if steam

is coming out.ProCarManuals.comMain Menu Table of Contents s t

If Your Engine Overheats

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 Emergency
Towing on page 311).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page187). 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 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 tomaximum (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 engineneeds repair. (See Emergency
Towing on page 311.)
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.

Taking Care of the Unexpected
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.ProCarManuals.comMain Menu Table of Contents s t
