2004 HONDA PILOT cooling

Your vehicle’s exhaust contains
carbon monoxide gas. You should
have no problem with carbon
monoxide entering the vehicle in
normal driving if you maintain your
vehicle properly.High levels of carbon monoxide can
collect rapidly in enclosed areas,
such as a garage. Do not run the
engine with the garage door closed.
Even with the door open, run the
engine only long enough to move the
vehicle out of the garage.
Have the exhaust system inspected
f or leaks whenever:
The vehicle is raised f or an oil
change.
You notice a change in the sound
of the exhaust.
The vehicle was in an accident
that may have damaged the under-
side. With the tailgate open, air flow can
pull exhaust gas into your vehicle’s
interior and create a hazardous
condition. If you must drive with the
tailgate open, open all the windows
and set the heating and cooling
system/climate control system as
shown below.
If you must sit in your parked vehicle,
even in an unconf ined area, with the
engine running, adjust the heating
and cooling system/climate control
system as f ollows:
Select the Fresh Air mode.
Select the mode.
Turn the f an on high speed.
Set the temperature control to a
comfortable setting.

Carbon Monoxide Hazard
Driver and Passenger Saf ety42
Carbon monoxide gas is toxic.
Breathing it can cause
unconsciousness and even kill
you.
Avoid any enclosed areas or
activities that expose you to
carbon monoxide.

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 white mark. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the pointer may rise to the
upper white mark. If it reaches the
red (Hot) mark, pull saf ely to the
side of the road. Turn to page f or
instructions and precautions on
checking the engine’s cooling
system.The temperature sensor is in the
f ront bumper. Theref ore, the temper-
ature reading can be af f ected by heat
ref lection f rom the road surf ace, en-
gine heat, and the exhaust f rom
surrounding traf f ic. This can cause
an incorrect temperature reading
when your speed is under
19 mph (30 km/h). This indicator displays the outside
temperature in Fahrenheit (U.S.
models) or Centigrade (Canadian
models). To see the outside
temperature, press and release the
Select/Reset button until the
temperature is displayed.
The sensor delays the display update
until it reaches the correct out side
temperature, this may take several
minutes.In certain weather conditions,
temperature readings near f reezing
(32°F, 0°C) could mean that ice is
f orming on the road surf ace.

The Automatic Climate Control
system can adjust the f an speed and
airflow levels to maintain the interior
temperature you select.
When you set the temperature to its
lower or its upper limit, the system
runs at f ull cooling or heating only. It
does not regulate the interior
temperature.
The system automatically selects the
proper mix of conditioned and/or
heated air that will, as quickly as
possible, raise or lower the interior
temperature to your pref erence. When you press a f an control button,
the fan is taken out of FULL AUTO
mode and starts to run at its lowest
speed. Press the button
repeatedly to make the f an run f aster.
When the
system is in FULL AUTO, the rear
A/C passenger control dial cannot
be used. Pressing the RR A/C button
disables the FULL AUTO f unction.
Press the AUTO button.
Set the desired temperature by
turning the Temperature Control
dial. You will see FULL AUTO in
the system’s display. You can manually select various
f unctions of the Climate Control
system when it is in FULL AUTO.
All other f eatures remain
automatically controlled. Making any
manual selection causes the word
FULL in the display to go out. See
page .
Press the OFF button. However, a
lack of air f low can cause the
windows to fog up. It is
recommended that you keep the f an
on at all times so stale air and
moisture do not build up in the
interior and cause fogging.

If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda antif reeze/coolant as soon as
possible.If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line.
Inspect the cooling system f or leaks.
Always use Honda All Season
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 percent
antif reeze and 50 percent water.
Never add straight antifreeze or
plain water. A dding Engine Coolant

RESERVE TANK
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.

When the radiator and engine are
cool, relieve any pressure in the
cooling system by turning the
radiator cap counterclockwise,
without pressing down.
Remove the radiator cap by
pushing down and turning
counterclockwise.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Pourthecoolantslowlyand
caref ully so you do not spill. Clean
up any spill immediately; it could
damage components in the engine
compartment.
Put the radiator cap back on and
tighten it.
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.
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. Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.
The low washer
level indicator will light when the
level is low.
Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition them.

NOTICE:
RADIATOR CAP
Do not use engine antif reeze
or a vinegar/water solution in the
windshield washer reservoir. Antif reeze
can damage your vehicle’s paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield
washer f luid.

If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator.
Using gloves or large heavy cloth,
turn the radiator cap
counterclockwise without pushing
down to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off.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 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.
