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.

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.

f You r Engin e Overheat s

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 climate control and all
other accessories. Turn on the
hazard warning indicators.
2. If you see steam
and/or spray
coming from under the hood, turn
of

f the engine.
3. I

f 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.

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.

4. If the temperature gauge stays at the red mark, turn off the engine.
5. Wait until you see no more signs of steam or spray, then open the

hood.

6. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you continue driving (see Emergenc y
Towin g on page 292).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page170). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
8. 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 pointer reaches the middle of the tempera-
ture gauge, or lower, before check- ing the radiator.
9. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first 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. 10. 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 filler neck. If you do
not have the proper coolant
mixture available, you can add
plai
n water. Remember to have
the cooling system drained and
refilled with the proper mixture as
soon as you can.
11. Put the radiator cap back
on
tightly. Run the engine and watch
the temperature gauge. If it goes
back t

o the red mark, the engine
needs repair. (See Emergenc y
Towin g o

n page 29
2.)
12. 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.

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.
