2003 HONDA ACCORD COUPE engine

The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
brake system inspected f or leaks or
worn brake pads.
Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 f luid, f rom a sealed
container, as a temporary
replacement. However, the use of
any non-Honda brake fluid can cause
corrosion and decrease the lif e of the
system. Have the brake system
f lushed and ref illed with Honda
Heavy Duty Brake Fluid DOT 3 as
soon as possible.
Check the f luid level in the reser-
voirs monthly. There are up to two
reservoirs, depending on the model.
They are:
Brake f luid reservoir (all models)
Clutch f luid reservoir
(manual transmission only)
The brake f luid should be replaced
according to the time recommenda-
tion in the maintenance schedule. Pour the f luid slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled f luid could
damage components in the engine
compartment.
Brake f luid marked DOT 5 is not
compatible with your car’s braking
system and can cause extensive
damage.Brake System

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.A low power steering f luid level can
indicate a leak in the system. Check
the f luid level f requently, and have
the system inspected as soon as
possible. Always use Honda Power Steering
Fluid. If it is not available, you may
use another power steering f luid as
an emergency replacement.
However, continued use can cause
increased wear and poor steering in
cold weather. Have the power
steering system f lushed and ref illed
with Honda PSF as soon as possible.
Pour the f luid slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled f luid could
damage components in the engine
compartment.

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.
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.
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
pages and .)

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.

Use a f lat-tipped screwdriver to
remove the two holding clips f rom
the inner f ender.
Pull the inner f ender cover away
f rom the f ender and bumper.
If you are changing the bulb on
the passenger’s side, start the
engine, turn the steering wheel all
the way to the left, and turn off the

steering wheel to the right.
Turn on the headlights to test the
new bulb.
