coolant level Acura MDX 2004 Owner's Manual

Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, seeon page f or
inf ormation on adding the proper
coolant. Always maintain your vehicle
according to the maintenance
schedule. See
(see page
). Try to maintain a constant speed.
Everytimeyouslowdownand
speed up, your vehicle uses extra
fuel.Usethecruisecontrolwhen
appropriate.
Combine several short trips into
one.
The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Usethefresh-air
ventilation when possible.
Refer to on page f or inf ormation
about checking other items on your
Acura. The build-up of snow or mud on
your vehicle’s underside adds
weight and rolling resistance.
Frequent cleaning helps your f uel
mileage and reduces the chance of
corrosion.
Drive moderately. Rapid
acceleration, abrupt cornering and
hard braking use more f uel.
Always drive in the highest gear
possible.an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses f uel.

Maintenance Schedule for Severe Conditions

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.
If it is not available, you may use
another major-brand non-silicate
coolant as a temporary replacement.
Make sure it 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.

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.

Make sure the engine and radiator
are cool.
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 fully.
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
come on when the level is low (see
page ).
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:
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 the temperature gauge stays at
the red mark, turn of f the engine.
Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (seeon page ). 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.
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
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 f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.
