Things You'll Need:
- Spark plug socket
- Socket wrench with extender
- Wire brush
- New spark plug
- Silicon spray
-
Step 1
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.
-
Step 2
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.
-
Step 3
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.
-
Step 4
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.
-
Step 5
Remove any debris or dirt in the well or in the wire boot with a wire brush.
-
Step 6
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.
-
Step 7
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.
-
Step 8
Replace the spark plug wire and turn it 180 degrees to the right and then back again until you hear a click.
-
Step 9
Repeat Steps 2 through 8 for the remaining spark plugs.
