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.Openthehood.Makesurethe

with a clean cloth.
Check the f luid level with the engine
at normal operating temperature.
Insert the dipstick all the way into
the transmission securely as
shown in the illustration.
Remove the dipstick and check
the f luid level. It should be
between the upper and lower
marks.
Park the car on level ground. Shut
of f the engine. If the level is below the lower
mark, add f luid into the tube to
bring it to the upper mark. Always
use Honda ATF-Z1 (Automatic
Transmission Fluid). If it is not
available, you may use a
DEXRON
III automatic
transmission f luid as a temporary
replacement. However, continued
use can affect shift quality. Have
the transmission f lushed and
ref illed with Honda ATF-Z1 as
soon as it is convenient.

To thoroughly f lush the transmission,
the technician should drain and ref ill
it with Honda ATF-Z1 (Automatic

If Honda MTF is not available, you
may use an SAE 10W-30 or 10W-40
viscosity motor oil with the API
Certif ication seal that says ‘‘FOR
GASOLINE ENGINES’’ as a
temporary replacement. However,
motor oil does not contain the proper
additives and continued use can
cause stif f er shif ting. Replace as
soon as it is convenient.

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.
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. 364

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.

An auto-tensioner adjusts the tension
of the drive belt. The pointer on the
auto-tensioner should be in the
proper range. It should be checked
accordingtothetimeanddistance
recommendations in the
maintenance schedule. Take your car to a Honda dealer to
replacethedrivebelt.
If the pointer is out of this range or
you see signs of wear, have the drive
belt replaced by your Honda dealer
as soon as possible.
Check the condition of the drive belt.
Examine the edges of the belt f or
cracks or fraying. In very high temperatures
(over 110°F, 43°C).
In very low temperatures
(under 20°F, 29°C).
Replace these belts at 60,000 miles
(U.S.) or 100,000 km (Canada) if you
regularly drive your car in one or
more of these conditions:
The timing belt and balancer belt
should normally be replaced at the
intervals shown in the maintenance
schedule.

If you see steam and/or spray
coming f rom under the hood, turn
of f the engine.
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.
Saf ely pull to the side of the road.
Put the transmission in Neutral or
Park, and set the parking brake.
Turn of f the heating and cooling
system and all other accessories.
Turn on the hazard warning
indicators.
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.
Your car can overheat f or 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 f rom under the hood.
In either case, you should take
immediate action. 1.

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
Driving with the temperature gauge
pointer at the red mark can cause
serious damage to your engine.

If the temperature gauge stays at
the red mark, turn of f the engine.
Wait until you see no more signs
of steam or spray, then open thehood.
If there was no coolant in the
reserve tank, you may also have to
add coolant to the radiator. Let the
engine cool down until the pointerreaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator.
Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes
off.
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank (see page
). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks. Start the engine and set the
temperature control dial to
maximum (climate control to
FULL AUTO at 90°F/32°C). Add
coolant to the radiator up to the
base of the f iller neck. If you do
not have the proper coolant
mixture available, you can add
plain water. Remember to have
the cooling system drained and
ref illed with the proper mixture as
soon as you can.
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (see
on page ). Put the radiator cap back on
tightly. Run the engine and watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair. (See on page .)
