2007 Acura TL engine overheat

When slowing down, you can get
extra braking from the engine by
shifting to a lower gear. This extra
braking can help you maintain a safe
speed and prevent your brakes from
overheating while going down a
steep hill. Before downshifting,
make sure the engine speed will not
go into the tachometer’s red zone in
the lower gear.
The manual transmission is
synchronized in all forward gears for
smooth operation. It has a lockout so
you cannot accidentally shift from
f if th to reverse instead of sixth (see
page ). When shif ting up or
down,makesureyoupushtheclutch
pedal down all the way, shift to the
next gear, and let the pedal up
gradually. When you are not shif ting,
do not rest your f oot on the clutch
pedal. This can cause your clutch to
wear out faster. Come to a full stop before you shift
into reverse. You can damage the
transmission by trying to shif t into
reverse with the vehicle moving.
Push down the clutch pedal, and
pause f or a f ew seconds bef ore
shif ting into reverse, or shif t into one
of the f orward gears f or a moment.
This stops the gears so they won’t
‘‘grind.’’
251The engine can be damaged if
you inadvertently downshif t into the wrong gear (f or example, going f romthird gear at high rpms to second gearinstead of upshif ting to f ourth gear; theengine speed limiter will not work in thissituation).

Note:
Rapid slowing or speeding-up
can cause loss of control on
slippery surfaces. If you crash,
you can be injured.
Use extra care when driving on
slippery surfaces.

Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator in the instrument
panel to come on. If this happens,
you will see which tire is losing
pressure on the multi-inf ormation
display along with a ‘‘CHECK TIRE
PRESSURE’’ message.When the low tire pressure indicator
is on, one or more of your tires is
signif icantly underinf lated. You
should stop and check your tires as
soon as possible, and inf late them to
the proper pressure as indicated on
the vehicle’s tire inf ormation placard.
It is possible that the pressures
shown on the multi-inf ormation
display and the pressures you
manually measure are slightly
dif f erent.
If the dif f erence is signif icant or you
cannot make the low tire pressure
indicator and message on the multi-
inf ormation display go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire.
Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure indicator may
come on unexpectedly. After inflating the tire(s) to the
proper pressure, the low tire
pressure indicator will remain on
until the vehicle is driven at a speed
more than 25 mph (40 km/h).

Theheadlightswereproperlyaimed
when your vehicle was new. If you
regularly carry heavy items in the
trunk, readjustment may be required.
Adjustment should be done by your
dealer or other qualif ied mechanic.Remove the left or right side
engine compartment cover f rom

caref ully pulling the cover out.
If youarereplacingthebulbon

intake cover by removing the two
f astener pins and pulling the cover
out. Then remove the upper part
of the air intake duct by pulling it
straight up.
The headlight bulbs are a type of
high voltage discharge tube. High
voltage can remain in the circuit
even with the light switch off and the
key removed. Because of this, you
shouldnotattempttoexamineor
change a headlight bulb yourself . If a
headlight bulb f ails, take your
vehicle to a dealer to have it replaced. 1.

Halogen bulbs get very hot when lit. Oil,

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,
the engine should start to cool
down almost immediately. If it
does, wait until the temperatu re
gauge comes down to the midpoint,
then continue driving.
The
pointer of the vehicle’s
temperature gauge should stay in
the midrange. If it climbs to the red
mark, you should determine the
reason (hot day, driving up a steep
hill, etc.).
If the vehicle overheats, you should
take immediate action. 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. If
the temperatu re gauge stays at
the red mark, turn off the engine.
Look for 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 ).
If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood. Saf ely pull to the side of the road.
Put the transmission in neutral
(M/T) or Park (A/T), and set the
parking brake. Turn of f all
accessories, and turn on the
hazard warning indicators.

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 the engine.

Put the radiator cap back on
tightly. Run the engine, and check
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.
Using
gloves or a 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.
If
you don’t find an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark
(see on
page ).
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. Start the engine, and set the
interior temperature to maximum.
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.
