Maintenance

Check the level in the windshield
washer reservoir at least monthly
during normal usage. In bad weather,
when you use the washers often,
check the level every time you stop
for fuel.
The windshield washer reservoir is
located
in the rear of the engine
compartment on the passenger's side. Check
the reservoir's fluid level by
removing the cap and looking at the
level gauge attached to the cap.
Windshield Washers
Fill the reservoir with a good-quality
windshield washer fluid. This
increases the cleaning capability and
prevents freezing
in cold weather.
When you refill the reservoir, clean
the edges of
the windshield wiper
blades with windshield washer fluid
on a clean cloth. This will help to
condition
the blade edges.
NOTICE
Do not use engine antifreeze or a
vinegar/water solution
in the
windshield washer reservoir.
Antifreeze can damage your car's paint,
while a vinegar/water solution can
damage the windshield washer pump.
Use only commercially-available
windshield washer fluid.

Spark Plugs
I NOTICE I
Tighten the spark plugs carefully. A
spark plug that is too loose can
overheat and damage the engine.
Overtightening can cause damage to
the threads
in the cylinder head.
7. Install the ignition coil. Reinstall
the bolt.
8. Repeat this procedure for the
other three spark plugs.
9. Reinstall the cover on the cylinder
bank. Reinstall the four hexagon
socket head cap bolts.

Air Conditioning System
Your car's air conditioning is a sealed
system. Any major maintenance,
such as recharging, should
be done
by a qualified mechanic. You can do
a couple of things to
make sure the
air conditioning works efficiently.
Periodically
check the engine's
radiator and air conditioning
condenser for leaves, insects, and
dirt
stuck to the front surface. These
block the air flow and reduce cooling
efficiency.
Use a light spray from a
hose or a soft
brush to remove them.
NOTICE
The condenser and radiator fins bend
easily. Only use a low-pressure
~pray
or soft-bristle brush to clean them.
182 Maintenance
Run the air conditioning at least once
a
week during the cold weather
months. Run it for 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 refrigerant.
If the air conditioning does not get as
cold
as before, have your dealer
check the system. Recharge the
system with Refrigerant HFC-134a
(R-134a). (See Specifications on page
245.)
NOTICE
Whenever you have the air conditioning
system serviced, make sure the service
facility uses a refrigerant recycling
system. This system captures the
refrigerant
for reuse. Releasing
refrigerant into the atmosphere can
damage the environment.

The air conditioning filter removes
pollen and dust from outside air the
heating and cooling system brings
into the interior.
It should be
replaced according to the time and
distance recommendations
in the
maintenance schedule.
This filter should be replaced every
30,000 miles (48,000 km) under
normal conditions.
It should be
replaced every
15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air from industry and
diesel-powered vehicles. Replace it
more often
if air flow from the
climate control system becomes less
than usual. Have the air conditioning
filter replaced by your Honda dealer.
Replacement
The air conditioning filter is located
in the engine compartment on the
passenger's side near the base of the
windshield.
1. Open the hood. Unclip the
windshield base by pulling it
up.
Air Conditioning Filter
2. Push the tab on the air
conditioning filter to unlock it
from the holder.
3. Remove the old filter. Put a new
filter in the holder and push it in
until it locks.
4. Put the pins on the windshield
base into their mating holes on the
support, and push the base down
until the pins snap
in.
Maintenance 183

Lights
Replacing Front Tum Signal and
Side Marker Light Bulbs
1. 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.
196 Maintenance
2. Use a flat-tipped screwdriver to
remove the three holding clips
from the inner fender.
3. Pull the inner fender cover back.
4. Remove the socket from the
headlight assembly by turning it
one-quarter turn counterclockwise.
5. Pull the bulb straight out of its
socket.
6. Install the new bulb in the socket.
7. Insert the socket back into the
headlight assembly.
Turn it
clockwise to lock it
in place.
8. Test the lights to make sure the
new bulb is working.
9. Put the inner fender in place.
Install the two holding clips. Lock
each clip in place by pushing on
the center.

Storing Your Car
If you need to park your car for an
extended period (more than one
month), there are several things you
should
do to prepare it for storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your car back on the road.
If
possible, store your car indoors.
• Fill the fuel tank.
• Change the engine oil and filter
(see page 159).
• Wash and dry the exterior
completely.
• Clean the interior. Make sure the
carpeting, floor mats, etc. are
completely dry.
• Raise the convertible top cover.
• Leave the parking brake off. Put
the transmission in Reverse.
202 Maintenance
• Block the rear wheels.
• If the car is to be stored for a
longer period, it should be
supported on jackstands so the
tires are off the ground.
• Leave one window open slightly (if
the car is being stored indoors).
• Disconnect the battery.
• Support the front wiper blade
arms with a folded 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
vehicle body wax to the painted
surfaces that mate with the door
and trunk seals.
• Cover the car with a "breathable"
cover, one made from a porous
material such as cotton.
Nonporous materials, such as
plastic sheeting, trap moisture,
which can damage
the paint.
• If possible, run the engine for a
while periodically (preferably once
a month).
If you store your car for 12 months
or longer, have your Honda dealer
perform the inspections called for
in
the 24 months/30,000 miles (48,000
km) maintenance schedule as soon
as you take it out of storage (see
page
148 ). The replacements called
for
in the maintenance schedule are
not needed unless the car has
actually reached that time or mileage.
