2003 HONDA CIVIC COUPE engine

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.
You should check the f luid level in
the power steering reservoir at least
once a year. 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.

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 page
.)
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.

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.

If you are changing the bulb on
the driver’s side, start the engine,
turn the steering wheel all the way
to the right, and turn off the
engine. If you are changing the
bulb on the passenger’s side, turn
the steering wheel to the left.
Reinstall the power steering
reservoir.
(Driver’s side)
Push the electrical connector onto
the tabs of the new bulb. Make
sure it locks in place.
Turn on the headlights to test the
new bulb.
Insert the new bulb into the hole,
making sure the tabs are in their
slots. Pivot the hold-down wire
back in place and clip the end into
the slot.
Install the rubber seal over the
back of the headlight assembly.
Make sure it is right side up; it is
marked ‘‘TOP.’’
Unclip the end of the hold-down
wire f rom its slot. Pivot it out of
the way and remove the bulb.
Remove the rubber weather seal
by pulling on the tab.
Remove the electrical connector
f rom the bulb by squeezing the
connector on both sides to unlock
the tab. Pull the connector straight
off.

Block the rear wheels.
Fill the f uel tank.
Change the engine oil and f ilter
(see page ).
Wash and dry the exterior
completely.

carpeting, floor mats, etc. are
completely dry.
Leave the parking brake off. Put
the transmission in Reverse
(5-speed manual) or Park
(automatic).
If you need to park your car f or an
extended period (more than one
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your car back on the road. If
possible, store your car indoors.
If the car is to be stored for a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the car is being stored indoors).
Disconnect the battery.
Support the f ront wiper blade
arms with a f olded towel or rag so
they do not touch the windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and trunk seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and trunk seals.Coverthecarwitha‘‘breathable’’
cover, one made f rom a porous
material such as cotton.
Nonporous materials, such as
plastic sheeting, trap moisture,
which can damage the paint.
If possible, run the engine f or a
while periodically (pref erably once
amonth).
If you store your car f or 12 months
or longer, have your Honda dealer
perf orm the inspections called f or in
the 24 months maintenance schedule
(Normal Conditions) as soon as you
take it out of storage (see page ).
The replacements called f or in the
maintenance schedule are not
needed unless the car has actually
reached that time or mileage. 194

Diagnosing why your engine won’t
start f alls into two areas, depending
on what you hear when you turn the
key to START (III):When you turn the ignition switch to
START (III), you do not hear the
normal noise of the engine trying to
start. You may hear a clicking sound
or series of clicks, or nothing at all.
Check these things:
You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run. Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the f loor or the
starter will not operate. With an
automatic transmission, it must be
in Park or Neutral.
Turn the ignition switch to ON (II).
Turn on the headlights and check
their brightness. If the headlights
are very dim or don’t light at all,
the battery is discharged. See
on page . Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
the f uses are OK, there is proba-
bly something wrong with the
electrical circuit f or the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. (See
on page .)
If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the car from
a booster battery (see page ).

If youfindnothingwrong,youwill
need a qualif ied technician to f ind
the problem. Seeon page .
In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run.
Your car has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page ).
A key that is not properly coded
will cause the immobilizer system
indicator in the dash panel to blink
rapidly.
Are you using the proper starting
procedure? Ref er to on page . Do you have f uel? Turn the
ignition switch to ON (II) for a
minute and watch the f uel gauge.
The low f uel level warning light
may not be working, so you were
not reminded to f ill the tank.
There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
