coolant temperature Acura TSX 2004 Owner's Manual

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 into the
upperhalfofthegauge.Ifitreaches
the red (Hot) mark, pull safely to the
side of the road. Turn to page f or
instructions and precautions on
checking the engine’s cooling
system.
This meter shows the number of
miles (U.S.) or kilometers (Canada)
driven since you last reset it.
This indicator displays the outside
Fahrenheit temperature in U.S.
models, and Centigrade temperature
in Canadian models.
The temperature sensor is located in
the f ront bumper. Theref ore, the
temperature reading can be af f ected
by heat ref lection f rom the road sur-
f ace, engine heat, and the exhaust
f rom surrounding traf f ic. This can
cause an incorrect temperature read-
ing when your speed is under
19 mph (30 km/h).
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. There are two trip meters: Trip A
and Trip B. Switch between these
displays by pressing the Select/
Reset knob repeatedly. Each trip
meter works independently, so you
can keep track of two dif f erent
distances.
When you turn the ignition switch to
ON (II), what you last selected is
displayed.
To reset a trip meter, display it and
then press and hold the Select/Reset
knob until the number resets to ‘‘0.0’’.
Both trip meters will reset if the car’s
battery goes dead or is disconnected.

Thecoolingsystemshouldbe
completely drained and ref illed with
new coolant according to the time
and distance recommendations in
the maintenance schedule. Only use
Honda All Season Antif reeze/
Coolant Type 2.
Draining the coolant requires access
to the underside of the car. Unless
you have the tools and knowledge,
you should have this maintenance
done by a skilled mechanic.Openthehood.Makesurethe
engine and radiator are cool to the
touch.
Remove the radiator cap.
Turn the ignition to ON (II). Make

The pointer of your car’s tempera-
ture gauge should stay in the mid-
range 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.Your car can overheat f or 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 f rom under the hood.
In either case, you should take
immediate action. Saf ely pull to the side of the road.
Put the transmission in Neutral or
Park and set the parking brake.
Turn of f the climate control and all
otheraccessories.Turnonthe
hazard warning indicators.
If you see steam and/or spray
coming f rom under the hood, turn
of f the engine.
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.

If Your Engine Overheats
T aking Care of t he Unexpect ed315
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
Driving with the temperature gauge
pointer at the red mark can cause
serious damage to your engine.

If the temperature gauge stays at
the red mark, turn of f the engine.
Wait until you see no more signs
of steam or spray, then open the
hood.
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 pointerreaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator.
Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst 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.
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank (see page
). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks. 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 (see on page ). Start the engine and set the
temperature control to its upper
limit, . 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.

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.
