6CHECKING AND CHANGING
THE ENGINE COOLANT
!

Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum engine parts. Ad-
ditional corrosion inhibitors or additives should
not be used. The cooling system must be main-
tained with the correct concentration and type of
engine coolant to prevent freezing and corro-
sion.
Never allow the concentration of antifreeze to
exceed the 60% level or go below the 35% level
or damage to the coolant system may result. For
proper concentration when adding or replacing
the coolant, refer to the following table.WARNING:Do not remove the radiator cap when the
engine is hot. When the engine is hot, the
engine coolant is under pressure and may
erupt through the opening if the cap is re-
moved. You could be seriously burned if you
do not observe this precaution. Do not re-
move the radiator cap until the radiator is
cool to the touch.

To Check the Coolant Level
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the coolant
should be between the "L" and "F" lines on the
reservoir when the engine is cool. If the level is
below the "L" mark, add engine coolant to bring
it up between "L" and "F". If the level is low,
inspect for coolant leaks and recheck the fluid
level frequently. If the level drops again, visit
your Hyundai dealer for an inspection and diag-
nosis of the reason.

To Change the Coolant
The coolant should be changed at those inter-
vals specified in the vehicle maintenance sched-
ule in Section 5.
CAUTION:Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking
brake and remove the radiator cap when
cool.
2. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow all
the engine coolant to drain from the cooling
system, then securely close the drain cock.
3. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer's directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
!
4. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclockwise.
Now fill the radiator with clean demineralized
or distilled water. Continue to add clean
demineralized or distilled water in small quan-
tities until the fluid level stays up in the
radiator neck.
G050D01AG050D02A
5. Start the engine, top off the radiator with
water and then add engine coolant to the
reservoir until the level is between "L" and
"F".
6. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.

8REPLACING THE SPARK PLUGS

0.039 ~ 0.043 in.
(1.0 ~ 1.1 mm )
The spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in section 5, or whenever engine per-
formance indicates they should be changed.
Symptoms that suggest poor spark plug perfor-
mance include engine misfiring under load, loss
of fuel economy, poor acceleration, etc. When
spark plugs are replaced, always use spark
plugs recommended by Hyundai. The use of
other spark plugs can result in loss of perfor-
mance, radio interference or engine damage.
NOTE:When replacing the spark plugs, genuine
Hyundai replacement parts are recom-
mended.
G060C01S-GATChanging the Spark Plugs
You will find it easier to change spark plugs if the
engine is cold. Always change one spark plug at
a time. This helps avoid getting the wires mixed
up.
G060C01A-D
1. Remove the center cover on the engine
rocker cover.
2. Using a clean cloth, remove any dirt that has
accumulated around the base of the spark
plug so it cannot fall into the cylinder when
the spark plug is removed.
Recommended Spark Plugs:CHAMPION : RC10YC4
NGK : BKR5ES-11!WARNING:The cooling fan is controlled by engine cool-
ant temperature and may sometimes operate
even when the engine is not running. Use
extreme caution when working near the
blades of the cooling fan so that you are not
injured by a rotating fan blade. As the engine
coolant temperature decreases, the fan will
automatically shut off. This is a normal con-
dition.

While the engine is idling, apply the brakes and
move the gear selector lever from "P" to each of
its other positions -- "R", "N", "D", "2", "L" -- and
then return to "N" or "P". With the engine still
idling:
1. Open the hood, being careful to keep hands,
hair and clothing clear of any moving parts.
2. Remove the transaxle dipstick, wipe it clean,
reinsert the dipstick as far as it will go, then
remove it again. Now check the fluid level on
the dipstick. It should be in the "HOT" range
on the dipstick.
G110D03A G110D02A-AAT
To Check the Transaxle Fluid Level
Park the car on level ground with the parking
brake engaged. When the transaxle fluid level is
checked, the transaxle fluid should be at normal
operating temperature and the engine idling.
C090A01A
!
3. If the transaxle fluid level is low, use a funnel
to add transaxle fluid through the dipstick
tube until the level reaches the "HOT" range.
Do not overfill.
G110D04A
Fluid level should be within
"HOT" range
WARNING:The cooling fan is controlled by the engine
coolant temperature and may sometimes op-
erate even when the engine is not running.
Use extreme caution when working near the
blades of the cooling fan, so that you are not
injured by a rotating fan blade. As the engine
coolant temperature decreases, the fan will
automatically shut off. This is a normal con-
dition.

15CHECKING THE CLUTCH FLUID
!
G130B02A-AAT
To Replace the Fluid
Recommended brake fluid conforming to DOT 3
or DOT 4 specification should be used. The
reservoir cap must be fully tightened to avoid
contamination from foreign matter or moisture.
NOTE:Do not allow any other liquids to contami-
nate the brake fluid. Seal damage will result.
WARNING:Use caution when handling brake fluid. It
can damage your vision if you get it in your
eyes. It will also damage your vehicles paint
if spilled on it and not removed immediately.
G130A01A-AAT
To Check the Clutch Fluid
The clutch fluid level in the master cylinder
should be checked when performing other un-
der hood services. The system should be
checked for leakage at the same time.
Check to make certain that the clutch fluid level
is between the "MAX" and "MIN" level markings
on the fluid reservoir. Fill as required. Fluid loss
indicates a leak in the clutch system which
should be inspected and repaired immediately.
Consult your Hyundai dealer.

AIR CONDITIONER CARE
G140A01A-AAT
Keeping the Condenser Clean
The air conditioner condenser (and engine ra-
diator) should be checked periodically for accu-
mulation of dirt, dead insects, leaves, etc. These
can interfere with maximum cooling efficiency.
When removing such accumulations, brush or
hose them away carefully to avoid bending the
cooling fans.

POWER STEERING HOSES
It is suggested that you check the power steer-
ing hose connections for fluid leakage at those
intervals specified in the vehicle maintenance
schedule in Section 5.
The power steering hoses should be replaced if
there is severe surface cracking, pulling, scuff-
ing or worn spots. Deterioration of the hose
could cause premature failure.
Recommended FluidUse PSF-3 type fluid
NOTE:Do not start the engine when the power
steering oil reservoir is empty.

Checking Engine Cooling Fan
The engine cooling fan should come on auto-
matically if the engine coolant temperature is
high.
WARNING:The radiator fan is controlled by engine cool-
ant temperature and may sometimes operate
even when the engine is not running. Use
extreme caution when working near the
blades of the cooling fan, so that you are not
injured by a rotating fan blade. As the cool-
ant temperature decreases the fan will auto-
matically shut off. This is a normal condition.
G220C01A-AAT
Checking Condenser Cooling Fan
The condenser cooling fan should come on
automatically whenever the air conditioner is in
operation.
HLC5006
The power steering fluid level should be checked
regularly. To check the power steering fluid
level, be sure the engine is "OFF", then check to
make certain that the power steering fluid level
is between the "MAX" and "MIN" level markings
on the fluid reservoir.
NOTE:Grinding noise from the power steering pump
may be heard immediately after the engine is
started in extremely cold conditions (below
-4°F). If the noise stops during warm up,
there is no abnormal function in the system.
It is due to a power steering fluid character-
istic in extremely cold conditions.
