The 2006 KIA Sorento is a smaller SUV with a 3.5-liter V6 engine. This engine uses six spark plugs to run the engine properly. There will be three spark plugs on each side of the engine. All six spark plugs will need to be changed at the same time to ensure that all six are working equally. The spark plugs are in plain sight on the right and left side of the engine and have rubber wires connected to the top of each one.
Insert the edge of the spark-plug gapping tool under the meal arm in the center of the one of the new spark plugs and turn the gapper until the number .038 is in the center of the metal arm. Repeat this for all other new spark plugs.
Open the hood of the 2006 KIA Sorento and remove a rubber wire from one of the spark plugs. Use the ratchet and spark-plug socket to remove that spark plug from the engine.
Insert the new spark plug into the hole where the old plug was. Hand-tighten the new spark plug until you are certain it is seated properly, then tighten it further using the ratchet and spark-plug socket. Replace the rubber wire to the top of the new spark plug.
Repeat for all other new spark plugs. Once you have replaced all six spark plugs and replace the rubber wires to the tops of them, close the hood.
