between the MAX and MIN lines. If
it is below the MIN line, see
on page f or
inf ormation on adding the proper
coolant. Refer to

If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
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. 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.

Make sure the engine and
radiator are cool.
Turn the radiator cap counter-
clockwise, without pressing down
on it, until it stops. This relieves
any pressure remaining in the
cooling system.
Remove the radiator cap by
pushing down and turning
counterclockwise.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.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.
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.
Pourthecoolantslowlyand
caref ully so you do not spill. Clean
up any spills immediately. Spilled
coolant could damage components
in the engine compartment.
Put the radiator cap back on.

you have the tools and knowledge,
you should have this maintenance
done by a skilled mechanic.

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.
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
.)
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.

AIR CONDITIONING CONDENSER
The condenser and radiator f ins bend
easily. Only use a low-pressure spray
or sof t-bristle brush to clean them.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.
