engine overheat Acura CL 2003 Owner's Manual

The manual transmission is synchro-
nizedinallforwardgearsforsmooth
operation. It has a lockout so you
cannot shift directly from Fifth to
Reverse instead of sixth (see page). When shif ting up or down,
make sure you push the clutch 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 f aster. Come to a full stop before you shift
into Reverse. You can damage the
transmission by trying to shif t into
Reverse with the car 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.’’
When slowing down, you can get
extra braking f rom the engine by
shifting to a lower gear. This extra
braking can help you maintain a safe
speed and prevent your brakes f rom
overheating while going down a
steep hill. Bef ore downshif ting,
make sure engine speed will not go
into the tachometer’s red zone in the
lower gear.

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.

This indicator will come on along
with the ABS indicator if there is a
problem in the anti-lock brake
system (seeon page
).
The TCS indicator may occasionally
come on f or one or two seconds and
then go out. This is normal.

you drove the vehicle.
The TCS indicator comes on or
f lashes under the f ollowing condi-
tions:
When you turn the ignition switch
to ON (II).
When you manually turn of f TCS. If the TCS indicator comes on and
stays on for more than 10 minutes
while driving, pull to the side of the
road when it is saf e and turn of f the
engine. Reset the system by
restarting the engine, and watch the
TCS indicator. If the indicator
remains on, or comes back on while
driving, have the system inspected
by your Acura dealer. You can still
drive the vehicle without TCS.
It f lashes when TCS is regulating
wheelspin.
If the system’s diagnostics senses
a problem with TCS, the indicator
will come on and stay on.

Taking Care of the Unexpected
T aking Care of t he Unexpect ed293

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. 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.
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.1.

If Your Engine Overheats
T aking Care of t he Unexpect ed306
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 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 ).
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.
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.
