3. Insert it all the way back in its tube.

4. Remove the dipstick again and
check the level. It should be
between the upper and lower marks.

If it is near or below the lower mark,
see Addin g Oi l on page 215 . Engine Coolant Check
Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, see Addin g
Engin e Coolan t on page 219 for
information on adding the proper

coolant.

Owne
r Maintenanc e Check s
You should check the following items at the specified intervals. If
you are unsure of how to perform any check, turn to the page given. Engine oil level — Check every
time you fill the fuel tank. See
page 169.
Engine coolant level — Check the
radiator reserve tank every time
you fill the fuel tank. See page 170.

Windshield washer fluid — Check the level in the reservoir monthly.If weather conditions cause you to
use the washers frequently, check
the reservoir each time you stop
for fuel. See page 225 . Automatic transmission — Check
the fluid level monthly. See page
226.
Brakes — Check the fluid level
monthly. See page 22 8 . Tires —
Check the tire pressure
monthly. Examine the tread for
wear and foreign objects. See page
241.
Lights — Check the operation of
the headlights, parking lights,
taillights, high-mount brake light,
turn signals, brake lights, and license plate lights monthly. See

page 248.

Maintenance

Coolin
g Syste m
Addin g Engin e Coolan t
If the coolant level in the reserve
tank is at or below the MIN line, add coolant to bring it up to the MAX line.
Inspect the cooling system for leaks.
This coolant should always be a mixture of 50 percent antifreeze and
50 percent water. Never add straight
antifreeze or plain water. Always use Genuine Honda
Antifreeze/Coolant. If it is not
available, you may use another
major-brand non-silicate coolant as a
temporary replacement. Make sure it is a high-quality coolant
recommended for aluminum engines.However, continued use of any non-
Honda coolant can result in
corrosion, causing the cooling system to malfunction or fail. Have
the cooling system flushed and
refilled with Honda antifreeze/
coolant as soon as possible. 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.

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.

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.

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.

Replacin g Engin e Coolan t
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 Genuine Honda Antifreeze/Coolant.
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. Turn the ignition ON (II). Turn
the heater temperature controldial to maximum heat (climate

control to 90°F/32°C). Turn off

the ignition. 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. Thecoolant will come out through the
hole in the splash cover.

4. On the right side of the engine block, remove the clip with a plier,
and then remove the drain cap. 5. Remove the reserve tank from its
holder by pulling it straight up.
Drain the coolant, then put the
tank back in its holder. 6. When the coolant stops draining,
tighten the drain plug at the
bottom of the radiator.
Put the drain cap back in place
tightly, then reinstall the clip on
the drain cap securely.
7. Mix the recommended antifreeze with an equal amount of purifiedor distilled water in a clean
container. The cooling system
capacity is:
1.61 US gal (6.1 l ,1.34 Imp gal)

8. Remove the two bolts and the three nuts with a 7/16 in (10 mm)
wrench, then remove the enginecover. 9. Loosen the bleeder bolt on top of
the engine.
Pour coolant into the radiator up to the base of the filler neck.
Tighten the bleeder bolt when
coolant comes out in a steady
stream with no bubbles. 10.Fill the reserve tank to the MAX
mark. Install the reserve tank cap.
11.Check the level in the radiator, add coolant if needed.

Batter
y

If your car's battery is disconnected
or goes dead, the engine's computer
needs to "relearn" the idle control.
After replacing or recharging the battery:
1. Make sure the climate control sys- tem is off.
2. Start the engine and let it run until it warms up (the radiator cooling
fan comes on at least twice), and
let it idle for five more minutes.
Your audio system will also disable it-

self when the battery is disconnected

or goes dead. The next time you turn

on the radio you will see "Code" in

the frequency display. Use the Pre-
set buttons to enter the five-digit

code (see page 162 ).
Charging the battery with the cables
connected can seriously damage your
car's electronic controls. Detach the
battery cables before connecting the

battey' to a charger.

Ai
r Conditionin g Syste m

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.

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 298.)

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.
