7. Pour coolant into the radiator up to the base of the filler neck. 8. Loosen the bleeder bolt on top of
the engine. Tighten it again whencoolant comes out in a steady
stream with no bubbles.
9. Refill the radiator to the base of the filler neck. Start the engineand let it run until it warms up (the
radiator cooling fan comes on at
least twice). 10. Turn off the engine. Check the
level in the radiator, add coolant if
needed. Install the radiator cap,
and tighten it fully.
11. Fill the reserve tank to the MAX mark. Install the reserve tank cap.

Windshield Washers

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 behind the driver's side
headlight. Check the reservoir's fluidlevel by removing the cap and
looking at the float. It should be up
to the top of the neck. If the float is at the bottom of the neck, the
reservoir is nearly empty.
Fill the reservoir with a good-quality
windshield washer fluid. This increases the cleaning capability and
prevents freezing in cold weather.
Do not use engine antifreeze or a
vinegar/water solution in the
windshield washer reservoir.
Antifreeze can damage your vehicle's
paint, while a vinegar/water solution
can damage the windshield washer

pump.

Use only commercially-available
windshield washer fluid.

Transmission Fluid

Automatic Transmission
Check the fluid level with the engine
at normal operating temperature.
1. Park the vehicle on level ground. Shut off the engine.
2. Remove the dipstick (yellow loop) from the transmission and wipe it
with a clean cloth. 3. Insert the dipstick all the way into
the transmission securely as
shown in the illustration.
4. Remove the dipstick and check the fluid level. It should bebetween the upper and lowermarks. 5. If the level is below the lower
mark, add fluid into the filler hole
to bring it to the upper mark.
Always use Honda Premium Formula Automatic Transmission
Fluid (ATF). If it is not available,
you may use a DEXRON ®
III
automatic transmission fluid as a
temporary replacement. However,
continued use can affect shift quality. Have the transmission
drained and refilled with Honda
ATF as soon as it is convenient.
6. Insert the dipstick all the way back into the transmission securely as
shown in the illustration.
The transmission should be drained and refilled with new fluid according
to the time and distance recommen-
dations in the maintenance schedule.

Brake and Clutch Fluid, Power Steering

Clutch System

The fluid should be between the MIN and MAX marks on the side of
the reservoir. If it is not, add brake
fluid to bring it up to that level. Use
the same fluid specified for the
brake system.
Low fluid level can indicate a leak in
the clutch system. Have this system inspected as soon as possible. Power Steering
Check the level when the engine is
cold. Look at the side of the
reservoir. The fluid should be
between the UPPER LEVEL and
LOWER LEVEL. If it is below the
LOWER LEVEL, add power steering
fluid to the UPPER LEVEL. Always use Genuine Honda Power
Steering Fluid. If it is not available,
you may use another power steering
fluid as an emergency replacement. However, continued use can cause
increased wear and poor steering in
cold weather. Have the power steering system flushed and refilled
with Honda PSF as soon as possible.
A low power steering fluid level can indicate a leak in the system. Check
the fluid level frequently and have
the system inspected as soon as
possible.
Turning the steering wheel to full left
or right lock and holding it there can
damage the power steering pump.

Air Cleaner Element
The air cleaner element should be cleaned or replaced according to the
time and distance recommendationsin the maintenance schedule.
Cleaning (Severe Conditions)
Clean the air cleaner element by
blowing compressed air through it in
the opposite direction to normal air
flow. If you do not have access to compressed air (such as a service
station), ask your Honda dealer to do
this service.
Follow the replacement procedure
for removal and reinstallation. Replacement
The air cleaner element is inside the air cleaner housing on the passenger'sside of the engine compartment.
To replace it:
1. Unsnap the four hold-down clamps and remove the air cleaner
housing cover.

Spark Plugs

5. Put the new spark plug into the socket; then screw it into the hole.
Screw it in by hand so you do not

crossthread it.
6. Torque the spark plug. (If you do
not have a torque wrench, tighten
the spark plug two-thirds of a turn
after it contacts the cylinder head.)
Tightening torque:
13 lbf .
ft (18 N .
m, 1.8 kgf .
m)

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 spark plug cap.
8. Repeat this procedure for the other three spark plugs.
Reinstall the plug wire cover and
tighten the four nuts.

Air Conditioning System
Your vehicle's air conditioning is a sealed system. Any major mainte-
nance, 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.

The condenser and radiator fins bend
easily. Only use a low-pressure spray
or soft-bristle brush to clean them.

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 255.)

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.
