2003 HONDA ACCORD COUPE engine overheat

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.
The manual transmission is syn-
chronizedinallforwardgearsfor
smooth operation. It has a lockout so
you cannot shift directly from Fifth
to Reverse. 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.

Your car is equipped with an
aluminum shif t lever. If you leave the
car parked outside f or a long time on
a hot day, be caref ul bef ore moving
the shif t lever. Because of the heat,
the shif t lever may be extremely hot.
If the outside temperature is low, the
shif t lever f eels cold.

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

When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air

necessary, pull to the side of the
road to let the engine cool.
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.

maneuvers bef ore heading f or the
open road, and f ollow the guidelines
discussed below.
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 car
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.
Drive slower than normal in all
driving situations, and obey posted
speed limits f or cars with trailers. If
you have an automatic transmission,
use 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 information.) If the automatic transmission shif ts

gears while going up a hill, shif t to

Do not try to hold the vehicle in

If you see steam and/or spray
coming f rom under the hood, turn
of f the engine.
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.

If Your Engine Overheats
T aking Care of t he Unexpect ed376
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 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, f or
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 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 (see
on page ).
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. 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.
