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.

7. Remove the two bolts and the
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)

11.Fill the reserve tank to the MAX
mark. Install the reserve tank cap.
12.Check the level in the radiator,
add coolant if needed.
13.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.

15.Start the engine and let it run until
the radiator cooling fan comes on
at least twice. Then stop the
engine.
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.
18.Install the radiator cap, and
tighten it fully.
19.If necessary, fill the reserve tank
to the MAX mark. Install the
reserve tank cap.

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.

If Your Engine Overheats
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 Emergency
Towing on page 296 ).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page172 ). 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 toadd 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 capcounterclockwise, 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 tomaximum (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
plain water. Remember to have
the cooling system drained andrefilled with the proper mixture assoon as you can.
11. 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 Emergency
Towing on page 296 .)
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.
Taking Care of the Unexpected
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.
