Heating and Cooling

These settings direct all the air flow to the defroster vents at the base of the windshield and the side windowdefroster vents. The air flow will get
warmer and clear the windows faster as the engine warms up. You can
close the corner vents with the dial
beside each vent. This will send more warm air to the windshielddefroster vents.
For safety, make sure you have a
clear view through all the windows
before driving away.
To Turn Everything Off To shut off the system temporarily, slide the fan speed and temperature
control levers all the way to the left.
TEMPERATURE CONTROL LEVER

You should shut the system com- pletely off only for the first few
minutes of driving in cold weather,until the engine coolant warms up
enough to operate the heater. Keep
the fan on at all other times so stale air does not build up in the interior.

Engine Oil, Cooling System

If you change your own oil, pleasedispose of the used oil properly. Put it in a sealed container and take it to arecycling center. Do not discard it in a
trash bin or dump it on the ground.
Checking the Engine Coolant
Level
Check the level of the engine coolant
by looking at the radiator reserve tank next to the battery. If the coolant level in the reserve tank is ator below the MIN line, add coolant to
bring it up to the MAX line. Inspect the cooling system for leaks. Thiscoolant should always be a mixtureof 50% antifreeze and 50% water.
Never add straight antifreeze or
plain water. Always use Genuine Honda Anti-
freeze/Coolant. The cooling systemcontains many aluminum compo-nents that can corrode if an improper
antifreeze is used. Some antifreeze,even though labeled as safe for
aluminum parts, may not provideadequate protection.

Cooling System

Adding Engine Coolant If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
1. Make sure the engine and radiator
are cool.
2. Turn the radiator cap counter-
clockwise, without pressing down
on it, until it stops. This relieves
any pressure remaining in the
cooling system.
3. Remove the radiator cap by pushing down and turning
counterclockwise.
4. The coolant level should be up to
the base of the filler neck. Add
coolant if it is low.
5. Put the radiator cap back on. Tighten it fully.
6. Pour coolant into the reserve tank. Fill it to halfway between the MAX
and MIN marks. Put the cap back
on the reserve tank.

Removing the radiator cap
while the engine is hot can cause the coolant to spray out,
seriously scalding you.
Always let the engine and radiator cool down before
removing the radiator cap. RADIATOR CAP

Cooling System

Do not add any rust inhibitors or
other additives to your car's cooling
system. They may not be compatible
with the coolant or engine compo-
nents.

Replacing Engine Coolant

The cooling system should be completely drained and refilled with
new coolant according to the time
and distance recommendations in
the maintenance schedule. Only use recommended antifreeze.
Draining the coolant requires access
to the underside of the car. Unless
you have the tools and knowledge,
you should have this maintenance done by a skilled mechanic. 1. Start the engine. Turn the heater
temperature control dial to
maximum heat and turn off the
engine. Open the hood. Make sure
the engine and radiator are cool to
the touch.
2. Remove the radiator cap. 3. Loosen the drain plug on the
bottom of the radiator. The
coolant will drain through the
splash guard. Remove the drain
bolt from the engine block.

4. Remove the reserve tank from its holder by pulling it straight up.
Drain the coolant, then put the tank back in its holder.
5. When the coolant stops draining, tighten the drain plug in the
bottom of the radiator. Apply non-hardening sealant to the drain bolt
threads and reinstall the bolt in
the engine block. Tighten it securely.

6. Mix the recommended antifreeze with an equal amount of purified
or distilled water in a clean
container. The cooling system

capacity is:6.3 (1.66 US gal, 1.39 Imp gal)

7. Pour coolant into the radiator up
to the base of the filler neck. BLEEDER BOLT
8. Loosen the bleeder bolt on top of the engine. Tighten it again when
coolant comes out in a steady
stream with no bubbles.
9. Refill the radiator to the base of the filler neck. Put the cap on the
radiator, only tighten it to the first
stop. Start the engine and 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,

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 left headlight.Check the reservoir's fluid level by
removing the cap and looking at the
level gauge attached to the cap.
Fill the reservoir with a good-quality
windshield washer fluid. This increases the cleaning capability andprevents freezing in cold weather.
Do not use engine antifreeze or a vinegar/water solution in the wind-
shield washer reservoir.
LEVEL GAUGE

Antifreeze can damage your car's pain while a vinegar/water solution can
damage the windshield washer pump.
Use only commercially-available

windshield washer fluid.

Air Conditioning

Your car's air conditioning is a sealed system. Any major maintenance,
such as recharging, should be done
by a qualified technician. There are a couple of things you can do to makesure the air conditioning works
efficiently.
Periodically check the engine's
radiator and air conditioning condenser for leaves, insects, anddirt 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.
AIR CONDITIONING
CONDENSER

Run the air conditioning at least once a week during the cold weather
months. Run it for at least tenminutes 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 thesystem with Refrigerant HFC-134a (R-134a). (See Specifications on page 218.)

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.

If Your Engine Overheats

The pointer of your car's tempera-
ture gauge should stay in the mid-

range under most conditions. It may

go higher if you are driving up a long
steep hill on a very hot day. If it

climbs to the red mark, you should
determine the reason.

Driving with the temperature gauge
pointer at the red mark can cause serious damage to your engine.
Your car can overheat for several

reasons, such as lack of coolant or a

mechanical problem. The only

indication may be the temperature

gauge climbing to or above the red

mark. Or you may see steam or
spray coming from under the hood.

In either case, you should take

immediate action.
1. Safely pull to the side of the road.
Put the transmission in neutral or
park and set the parking brake.
Turn off the heating and cooling system and all other accessories.
Turn on the hazard warning indicators.
2. If you see steam and/or spray coming from under the hood, turnoff the engine.
3. If you do not see steam or spray, leave the engine running and
watch the temperature gauge. If the high heat is due to overloading (climbing a long, steep hill on a
hot day with the A/C running, for example), the engine should start
to cool down almost immediately. If it does, wait until the tempera-
ture gauge comes down to the mid
point then continue driving.
Taking Care of the Unexpected

NOTICE

Steam and spray from an

overheated engine can

seriously scald you.

Do not open the hood if steam

is coming out.ProCarManuals.coms t Main Menu Table of Contents
