Replacing the Spark Plugs
The spark plugs should be changed
at the intervals specified in the ve- hicle maintenance schedule in Sec- tion 5 or whenever engine perfor- mance indicates they should bechanged. Symptoms that suggest poor spark plug performance include en- gine misfiring under load, loss of fueleconomy, poor acceleration, etc. When spark plugs are replaced, al- ways use spark plugs recommendedby Hyundai. The use of other spark plugs can result in loss of perfor- mance, radio interference or enginedamage.
NOTE:
o When replacing the spark plug, Genuine Hyundai ReplacementParts are recommended. Recommended Spark Plugs:
NOTE: Do not clean or regap platinum- tipped spark plugs.
o Spark plugs should be tightenedfirmly. Overtightening can dam- age the threads in the aluminum cylinder head. Also, leavingthem too loose can cause the spark plug to get very hot and possibly result in damage to theengine.
o It is recommended that spark
plugs be changed by an autho-rized Hyundai dealer.
