Solution
1. Preparation
  • Gather tools and parts before starting the replacement.
  • Tools Required:
    • Socket set (10mm and 5/8" spark plug socket)
    • Torque wrench
    • Spark plug gap tool
    • Ratchet
    • Extension bar
    • Compressed air (optional for cleaning)
  • Parts Required:
    • New spark plugs (refer to owner's manual for specifications)
  • Safety Warnings:
    • Disconnect the battery before starting work to prevent electrical shock.
2. Remove Engine Cover (if applicable)
  • Use a socket wrench to remove the screws or bolts securing the engine cover.
  • Carefully lift the engine cover off and set it aside.
3. Access Spark Plugs
  • Locate the ignition coils on top of the spark plugs.
  • Disconnect the electrical connectors from each ignition coil by pressing the release tab and pulling it off.
4. Remove Ignition Coils
  • Use a socket wrench to unscrew the bolts holding each ignition coil in place.
  • Carefully pull each ignition coil out, wiggling slightly if necessary to break the seal.
5. Remove Old Spark Plugs
  • Use a spark plug socket and ratchet to unscrew each old spark plug.
  • If necessary, use compressed air to blow away any debris around the spark plug hole before removal.
6. Install New Spark Plugs
  • Set the gap on each new spark plug to the manufacturer-recommended specification using a spark plug gap tool.
  • Carefully thread each spark plug into the cylinder head by hand to avoid cross-threading.
  • Use a torque wrench to tighten each spark plug to the specified torque (usually around 13 lb-ft, but verify with the owner's manual).
7. Reinstall Ignition Coils
  • Place each ignition coil back onto its corresponding spark plug.
  • Secure with the bolts and reconnect the electrical connectors.
8. Reattach Engine Cover
  • Position the engine cover back in place and secure it with bolts or screws.
9. Reconnect Battery
  • Reconnect the negative battery terminal and ensure it is tight.
