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 f or leaks.
The coolant you add should always
be a mixture of 50 percent antif reeze
and 50 percent water. Never add
straight antif reeze or plain water.If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
Make sure the engine and radiator
are cool.
Always use Honda All Season
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 percent
antif reeze and 50 percent water. It
does not require any additional
mixing.
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 f or aluminum engines.
However, continued use of any non-
Honda coolant can result in
corrosion, causing the cooling
system to malf unction or f ail. Have
the cooling system f lushed and
ref illed with Honda antif reeze/
coolant as soon as possible.

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.
01/09/28 20:03:12 31SZ3660_234

Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap back
on the reserve tank. Put the radiator cap back on.
Tighten it f ully. The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Remove the radiator cap by
pushing down and turning
counterclockwise. Turn the radiator cap counter-
clockwise, without pressing down
on it, until it stops. This relieves
any pressure remaining in the
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.

Loosen the drain plug on the
bottom of the radiator. The
coolant will come out through the
hole in the splash cover.
Turn the ignition ON (II). Turn
the heater temperature control
dial to maximum heat (climate
control to 90°F/32°C). Turn of f
the ignition. Open the hood. Make
sure the engine and radiator are
cool to the touch.
Remove the radiator cap.
Thecoolingsystemshouldbe
completely drained and ref illed with
new coolant according to the time
and distance recommendations in
the maintenance schedule. Only use
Honda All Season Antif reeze/
Coolant Type 2. Use of any non-
Honda coolant or plain water can
result in corrosion and deposits in
the cooling system.
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.

wrench, then remove the engine
cover.Loosen the bleeder bolt on top of
the engine.Pour Honda All Season
Antif reeze/Coolant Type 2 into

Install the radiator cap, and
tighten it fully.
If necessary, f ill the reserve tank
to the MAX mark. Install the
reserve tank cap.
Remove the radiator cap. Pour
coolant into the radiator up to the
base of the f iller neck and into the
reserve tank up to the MAX mark.
Start the engine and hold it at
1,500 rpm until the cooling f an
comes on. Turn of f the engine.
Check the coolant level in the
radiator and add coolant if needed. Install the engine cover. First
tighten the two bolts on the front
of the engine cover, then tighten
the three nuts on the engine cover.
Tightening torque:
Install the radiator cap, and
tighten it to the first stop.
Start the engine and let it run until
the radiator cooling f an comes on
at least twice. Then stop the
engine.
Fill the reserve tank to the MAX
mark. Install the reserve tank cap.
Check the level in the radiator,
add coolant if needed.

Make sure the climate control sys-
tem is off.
Start the engine and let it run until
it warms up (the radiator cooling
fan comes on at least twice), and
let it idle f or f ive more minutes.
If your car’s battery is disconnected
or goes dead, the engine’s computer
needs to ‘‘relearn’’ the idle control.
Af ter replacing or recharging the
battery:
Your driver’s power window (see
page ) and your audio system
will also disable itself when the bat-
tery is disconnected or goes dead.
Thenexttimeyouturnontheradio
you will see ‘‘Code’’ in the f requency

Charging the battery with the cables

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.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
.)
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. 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. 312

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.
