2. Pull the spark plug wires off of the spark plugs and
remove the plugs from the cylinder head.
3. Check the condition of the side electrode, center
electrode, and center electrode insulator to ensure that
there is no damage.
Figure 33
Important A cracked, fouled, dirty or malfunctioning
spark plug must be replaced. Do not sand blast, scrape, or
clean the electrodes by using a wire brush because grit may
eventually release from the plug and fall into the cylinder.
The result is usually a damaged engine.
4. Set the air gap between the center and side electrodes at
0.030 in. (0.76 mm). Install the correctly gapped spark
plug and tighten the plug to 18–22 ft.-lb. (24–30 N m).
If a torque wrench is not used, tighten the plug firmly.
5. Install the spark plug wires.
