6. When the coolant stops draining,
tighten the drain plug at
the
bottom of the radiator.
Apply non-hardening sealant to the
drain bolt threads, put a new
washer on the drain bolt, and
reinstall
the bolt in the engine
block. Tighten it securely.
Tightening torque:
61 lbf.ft (83 N·m I 8.5 kgf·m)
7. Mix the recommended antifreeze
with an equal amount of purified
or distilled water
in a clean
container.
The cooling system
capacity
is:
1.72 US gal (6.5 Q I 1.43 Imp gal)
8. Loosen the bleeder bolt on top of
the engine, and remove
the
bleeder cap near the engine oil fill
cap. Pour coolant into the radiator
up to the base of
the filler neck.
Tighten the bleeder bolt and
reinstall the bleeder cap when
coolant comes out in a steady
stream with no bubbles.

9. Start the engine and let it run for
about
30 seconds. Then turn off
the engine.
lO.Pour coolant into the radiator up
to the base of the filler neck.

12.Install the radiator cap, and
tighten it to
the first stop.
13.Start the engine and let it run until
the radiator fan comes on two
times.
Then stop the engine.

16.Start
the engine and hold it at
1,500 rpm until the radiator fan
comes on.
Turn off the engine.
Check the coolant level in the
radiator and add coolant
if needed.

Maintenance

1. Open the hood.
If you need to change the high
beam headlight bulb on the left
side, remove the coolant reserve
tank from its holder by pulling it
straight up.
2. Remove the electrical connector
from
the bulb by squeezing the
connector to unlock the tab, then
slide
the connector off the bulb.
3. Remove the rubber weather seal
by pulling on the tab.
4. Unclip the end of the hold-down
wire from its slot.
Pivot it out of
the way and remove the bulb
socket.
5. Pull the bulb straight out of its
socket.
Push the new bulb straight into
the socket until it bottoms.
Lights
6. Insert the socket back into the
headlight assembly. Make sure
the bulb is installed correctly by
looking through the headlight lens.
The pins on the base of the bulb
should fit in
the holes in the
headlight assembly.
Pivot the hold­
down wire back in place and clip
the end into the slot.
7. Install the rubber seal over the
back of
the headlight assembly.
Make sure it is right side
up; it is
marked
''TOP."
8. Push the electrical connector onto
the new bulb.
Turn on the headlights to test the
new bulb.

The reading on your car's
temperature gauge should stay in
the midrange 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.
NOTICE
Driving with the temperature gauge
reading
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 car or
engine cover. In either case, you
should take immediate action.
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
1. Safely pull to the side of the road.
Put the transmission in Neutral
and
set the parking brake. Turn
off the heating and cooling system
and all
other accessories. Turn on
the hazard warning indicators.
2. If you see steam and/ or spray
coming from
under the hood, turn
off
the engine.
If Your Engine Overheats
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, 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.
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.

If Your Engine Overheats
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 238 ) .
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.
224 Taking Care of the Unexpected
7. If you don't find an obvious leak,
check the coolant level in
the
radiator reserve tank (see page
120 ) . 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 reading
reaches the middle of the
temperature gauge, or lower,
before checking 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.

lO.Start the engine and set the
temperature control dial to
maximum. 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 and refilled with
the proper mixture as soon as you
can.
ll.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 238 .)
If Your Engine Overheats
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.
