Cooling System

Adding Engine Coolant
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 Honda All Season
Antifreeze/Coolant Type 2. This coolant is pre-mixed with 50 percent
antifreeze 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 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.

RESERVE TANK

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.

Cooling System

2. Turn the radiator rap 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 coolingsystem. They may not be compatible
with the coolant or engine compo- nents.

Replacing Engine Coolant
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 Honda All Season Antifreeze/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.
1. Turn the ignition ON (II). Turn
the heater temperature control
dial 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. The
coolant 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.

three nuts with a 7/16 in (10 mm)
wrench, then remove the engine
cover.

8. Loosen the bleeder bolt on top of

the engine.

9. Pour Honda All Season

Antifreeze/Coolant Type 2 into the radiator up to the base of the
filler neck. This coolant is a
mixture of 50 percent antifreeze
and 50 percent water. Pre-mixing
is not required.
The cooling system capacity is:
1.61 US gal (6.1 , 1.34 Imp gal)

coolant comes out in a steady
stream with no bubbles.

16.Remove the radiator cap. Pour

coolant into the. radiator up to the base of the filler neck and into the
reserve tank up to the MAX mark.

17.Start the engine and hold it at

1,500 rpm until the cooling fan comes on. Turn off the engine.
Check the coolant level in the
radiator and add coolant if needed.

If Your Engine Overheats
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 longsteep 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, turnoff the engine.
3. 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, forexample), 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.

Taking Care of the Unexpected

NOTICE

Steam and spray from an

overheated engine can

seriously scald you.

Do not open the hood if steam

is coming out.
