REPLACING 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.
Recommended Spark Plugs:
CHAMPION : RC10YC4
NGK : BKR5ES-11

Changing 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.
G060A01L
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.
3. To remove the spark plug cable, pull straight
up on the insulated connector, not the cable.
Pulling on the cable may damage the carbon
core conductor.
!
WARNING:
It is recommended that the engine be cool or
cold when changing the spark plugs. If the
engine is hot, you could burn yourself on the
insulated connector, the spark plug or the
engine itself.
4. When preparing to remove the old spark
plug, guide the socket down over the spark
plug, being careful not to damage the ce-
ramic insulator.
