Learning how to change spark plugs for a 2001 Kia Sephia every 15,000 miles ensures that your vehicle continues running properly. Changing the spark plugs on your 2001 Kia Sephia can seem like a daunting task, but in actuality it is quite simple and requires nothing more than a few basic hand tools. You can follow these steps to change out old or defective spark plugs in your 2001 Kia Sephia.

To change the spark plugs on your 2001 Kia Sephia, you will need:

  • A socket wrench
  • Deep well sockets
  • A socket wrench extension
  • A spark plug gap measurement tool
  • The Kia Sephia owner's manual
  • Four standard spark plugs
  • Dielectric grease
  • A torque wrench
  1. Open the hood of your Kia Sephia. You can do this by popping the latch inside the cabin and then pulling the latch on the outside and lifting up.
  2. Locate the plug wires. They run from the head of the engine and connected to your coil pack distributor. Pull the first plug wire on your left out of the engine.
  3. Remove the first spark plug with a socket wrench and deep well socket. You might have to use a socket extension. Test a few different sockets and ensure that you use the correct size so that you don't damage the plug bolt.
  4. Measure and adjust the new spark plug gap. Refer to your owner's manual for the correct gap distance for the new spark plugs.
  5. Apply dielectric grease to the ceramic portion of the plug and to the plug wires. Be cautious not to get it on the actual firing mechanism.
  6. Insert the new spark plug into the deep well socket and insert it into the engine head. Line up the threads properly and tighten it using a torque wrench to the correct specifications (refer to your owner's manual for the appropriate torque value).
  7. Replace the plug wire over the spark plug. Repeat this process on each of the other three spark plugs in your Kia Sephia, only changing one plug at a time so that you don't get the plug wires confused.
