2003 HONDA ACCORD check engine

Always use Honda All Season
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 percent
antif reeze and 50 percent water. It
does not require any additional
mixing. If it is not available, you may
use another major-brand non-silicate
coolant as a temporary replacement.
Make sure it is a high-quality coolant
recommended f or aluminum engines.
However, continued use of any non-
Honda coolant can result incorrosion, causing the cooling
system to malf unction or f ail. Have
the cooling system f lushed and
ref illed with Honda antif reeze/
coolant as soon as possible.
If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
Make sure the engine and radiator
are cool.
Turn the radiator cap counter-
clockwise, without pressing down
on it, until it stops. This relieves
any pressure remaining in the
cooling system.
Remove the radiator cap by
pushing down and turning
counterclockwise.

The cooling system capacity is: Start the engine and let it run forabout 30 seconds. Then turn of f
the engine.
Fill the radiator with coolant up to
the base of the f iller neck.
Fill the reserve tank to the MAX
mark. Install the reserve tank cap.
Install the radiator cap, and
tighten it to the first stop.
Start the engine and let it run until
the radiator cooling f an comes on
at least twice. Then stop the
engine.
Remove the radiator cap. Pour
coolant into the radiator up to the
base of the f iller neck and into the
reserve tank up to the MAX mark.Start the engine and hold it at
1,500 rpm until the cooling f an
comes on. Turn of f the engine.
Check the coolant level in the
radiator and add coolant if needed.
Install the radiator cap, and
tighten it fully.
If necessary, f ill the reserve tank
to the MAX mark. Install the
reserve tank cap.

Check the level in the windshield
washer reservoir at least monthly
during normal usage. In bad weather,
when you use the washers of ten,
check the level every time you stop
for fuel.
Check the reservoir’s f luid level by
removing the cap and looking at the
level gauge attached to the cap.
The low washer level indicator will
light when the level is low (see page).
Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather. When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition the blade edges.
The windshield washer reservoir is
located behind the right headlight.

Do not use engine antif reeze or a
vinegar/water solution in the
windshield washer reservoir.
Antif reeze can damage your car’s paint,
while a vinegar/water solution can
damage the windshield washer pump.
Use only commercially-available
windshield washer f luid.

Remove the dipstick (yellow loop)
f rom the transmission and wipe it
with a clean cloth.
Check the f luid level with the engine
at normal operating temperature.
Insert the dipstick all the way into
the transmission securely as
shown in the illustration.
Remove the dipstick and check
the f luid level. It should be
between the upper and lower
marks.
Park the car on level ground. Shut
of f the engine. If the level is below the lower
mark, add f luid into the tube to
bring it to the upper mark. Always
use Honda ATF-Z1 (Automatic
Transmission Fluid). If it is not
available, you may use a
DEXRON
III automatic
transmission f luid as a temporary
replacement. However, continued
use can affect shift quality. Have
the transmission f lushed and
ref illed with Honda ATF-Z1 as
soon as it is convenient.

If you are not sure how to add f luid,
contact your Honda dealer.
To thoroughly f lush the transmission,
the technician should drain and ref ill
it with Honda ATF-Z1 (Automatic
Transmission Fluid), then drive the
car a short distance. Do this three
times. Then drain and ref ill the

If Honda MTF is not available, you
may use an SAE 10W-30 or 10W-40
viscosity motor oil with the API
Certif ication seal that says ‘‘FOR
GASOLINE ENGINES’’ as a
temporary replacement. However,
motor oil does not contain the proper
additives and continued use can
cause stif f er shif ting. Replace as
soon as it is convenient.
The transmission should be drained

Check the f luid level with the
transmission at normal operating
temperature and the car sitting on
level ground. Remove the
transmission f iller bolt and caref ully
f eel inside the bolt hole with your
f inger. The f luid level should be up
to the edge of the bolt hole. If it is
not, add Honda Manual Transmis-
sion Fluid (MTF) until it starts to
run out of the hole. Reinstall the
f iller bolt and tighten it securely.

The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If it is not, add
brake f luid to bring it up to that level.
Use the same fluid specified for the
brake system.
Low f luid level can indicate a leak in
the clutch system. Have this system
inspected as soon as possible.Check the level when the engine is
cold. Look at the side of the
reservoir. The f luid should be
between the UPPER LEVEL and
LOWER LEVEL. If it is below the
LOWER LEVEL, add power steering
f luid to the UPPER LEVEL.

Run the air conditioning at least once
a week during the cold weather
months. Run it f or at least ten
minutes while you are driving at a
steady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the ref rigerant.If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the
system with Ref rigerant HFC-134a
(R-134a). (See Specif ications on page
.)
Your car’s air conditioning is a sealed
system. Any major maintenance,
such as recharging, should be done
by a qualif ied mechanic. You can do
a couple of things to make sure the
air conditioning works ef f iciently.
Periodically check the engine’s
radiator and air conditioning
condenser f or leaves, insects, and
dirt stuck to the f ront surf ace. These
block the air f low and reduce cooling
ef f iciency. Use a light spray f rom a
hose or a sof t brush to remove them. 364

Whenever you have the air conditioning
system serviced, make sure the service
f acility uses a ref rigerant recycling
system. This system captures the
ref rigerant f or reuse. Releasing
ref rigerant into the atmosphere can
damage the environment.
The condenser and radiator f ins bend
easily. Only use a low-pressure spray
or sof t-bristle brush to clean them.
