How to Replace Spark Plugs in a Chevy Camaro

Save

Chevy Camaro spark plugs are manufactured to last 60,000 to 100,000 miles, depending on the brand. The Chevrolet Cooperation suggests that you inspect and clean spark plugs every 30,000 to 40,000 miles. If the spark plug is coated in carbon or debris, replace the spark plugs to maintain an efficient engine.

Things You'll Need

  • Spark plug socket
  • Socket wrench with extender
  • Wire brush
  • New spark plug
  • Silicon spray
  • Allow the engine to cool before removing the spark plugs. Removing a spark plug from a warm engine causes damage to the cylinder block, especially in aluminum engines.

  • Locate the spark plugs, which plug directly into both sides of the engine block. On the newer models with dust covers, they are located below the cover.

  • Grab the end of the spark wire that is connected to the engine. The cap, or cover, on the end of the wire is called a "boot." Always pull a spark plug wire by the boot. Turn the boot 180-degrees to the right and then 180-degrees to the left. This releases the lock on the spark plug. Pull back on the boot to remove the wire. Remove and replace one spark plug at a time to cut down on confusion when putting the wires back.

  • Insert the socket and socket wrench into the spark plug well and over the spark plug itself. Do not use a flexible extension, as the force can break the plug. Turn the socket wrench to the left to loosen it from the well. Pull the old socket out with the wrench.

  • Remove any debris or dirt in the well or in the wire boot with a wire brush.

  • Spray the new spark plug threads and wire boot with silicon spray to ensure the spark plug or wire don't stick together or to the spark plug well.

  • Insert the spark plug into the well and thread it by hand to reduce the chance of cross threading. Tighten the spark plug 1/4 turn with the socket, if you have a spark plug with a crush washer. If the Camaro requires a tapered spark plug, use a tension tester tool to set the tension to the specifications listed on the package.

  • Replace the spark plug wire and turn it 180 degrees to the right and then back again until you hear a click.

  • Repeat Steps 2 through 8 for the remaining spark plugs.
