DO-IT-YOURSELF MAINTENANCE

.  Start  the engine,  top off  the  radiator with
water and  then add engine  coolant to  the
reservoir until  the level is  between "LOW"
and "FULL".
The  spark  plugs  should be  changed  at  the
intervals specified in the vehicle maintenances
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.
6
.  Replace the radiator and reservoir caps and
check to  be sure the  drain cocks are  fully
closed and not leaking.
WARNING:
The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper-
ate 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 en-
gine coolant temperature decreases, the fan
will automatically shut off. This is a normal
condition.

Turn the radiator cap counterclockwise with-
