2003 Acura TL coolant temperature

This shows how much f uel you have.
It is most accurate when the car is on
level ground. It may show slightly
more or less than the actual amount
whenyouaredrivingoncurvyor
hilly roads.
The needle returns to the bottom
after you turn off the ignition. The
gauge shows the f uel level reading
immediately af ter you turn the
ignition switch back ON (II).
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 red 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.
This indicator displays the outside
temperature in Fahrenheit in U.S.
models, and in Centigrade 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 the surrounding traf f ic. This
can cause the temperature reading
not to be correct 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.

Avoid driving with an extremely low
f uel level. Running out of f uel could
cause the engine to misf ire, damaging
the catalytic converter.

Remove the reserve tank f rom its
holder by pulling it straight up.
Drain the coolant, then put the
tank back in its holder.
When the coolant stops draining,
tightenthedrainplugatthe
bottom of the radiator.
Turn the ignition ON (II). Turn
the heater temperature control
dial to maximum heat (climate
control to 90°F/32°C). Turn of f
the ignition. Open the hood. Make
sure the engine and radiator are
cool to the touch.
Remove the radiator cap. Loosen the drain plug on the
bottom of the radiator. The
coolant will drain through the
splash guard.
Install a rubber hose on the drain
bolt at the rear of the engine
cylinder block. Loosen the drain
bolt.

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 car or
engine cover. 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 ed299
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.
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 ).
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, 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. 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.
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. 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 .)

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.
