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.
1. Remove the engine rocker cover.
NOTE:It is recommended that the spark plugs (For
2.7L Engines) should be changed by an
authorized Hyundai dealer.
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.
HGK256
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. 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.
HGK257 G060B02GK-AAT
Replacing the Spark Plugs
The spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in Section 5 or whenever engine
performance 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:

5. To remove the old spark plug, turn the
wrench handle in a counterclockwise direc-
tion.
6. To install the new spark plug, guide the
socket down over the spark plug, being
careful not to damage the ceramic insulator.
NOTE:Spark plugs should be tightened firmly.
Over-tightening can damage the threads in
the aluminum cylinder head. Also, leaving
them too loose can cause the spark plug to
get very hot and possibly result in damage
to the engine.
7. Replace the cable by pushing the insulated
connector directly down onto the electrode.
Check to be sure it has snapped into place
and can't fall off.
