2004 Acura RL engine overheat

CONT INUED
When driving down hills, reduce
your speed and shif t down to 2nd
gear. Do not ‘‘ride’’ the brakes, and
remember it will take longer to slow
downandstopwhentowingatrailer.
When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air
conditioning of f , reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.
If the automatic transmission shif ts
f requently between 3rd and 4th
gears while going up a hill, shif t to
D.
The added weight, length, and
height of a trailer will af f ect your car’s
handling and perf ormance, so
driving with a trailer requires some
special driving skills and techniques.
Foryoursafetyandthesafetyof
others,taketimetopracticedriving
maneuvers bef ore heading f or the
open road, and f ollow the guidelines
discussed below.
Drive slower than normal in all
driving situations, and obey posted
speed limits f or vehicles with trailers.
Use the D position when towing a
trailer on level roads. D is the
proper shif t lever position to use
when towing a trailer in hilly terrain.
(See ‘‘
’’ in the next
column f or additional gear
inf ormation.) Make turns more slowly and wider
than normal. The trailer tracks a
smaller arc than your car, and it can
hit or run over something the vehicle
misses. Allow more time and
distance f or braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknif e or turn over.
If youmuststopwhenfacinguphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in
placebypressingontheaccelerator,
as this can cause the automatic
transmission to overheat.

Install the ignition coil. Reinstall
the two hold-down bolts.
Repeat this procedure f or the
other f ive spark plugs.
Torque the spark plug. (If you do
not have a torque wrench, tighten
the spark plug two-thirds of a turn
af ter it contacts the cylinder head.)
Tightening torque: Put the A/C tube back in place.
Install the tower bar and tighten
the two bolts and the f our nuts.
Tightening torque:
Push the wire connector onto the
ignition coil. Make sure it locks in
place. Install the engine cover. First

Overtightening can cause damage to
the threads in the cylinder head.

Taking Care of the Unexpected
T aking Care of t he Unexpect ed307

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 ed319
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.
