Remove the plug wires from the plugs, then remove the spark plugs from the engine with a 5/8 inch spark plug socket. (engine needs to be cold)
If installing the spark plugs to an existing cylinder head tighten the spark plugs to 15N m (11 lb ft).
Notice: Be sure plug threads smoothly into cylinder head and is fully seated. Use a thread chaser if necessary to clean threads in cylinder head. Cross-threading or failing to fully seat spark plug can cause overheating of plug, exhaust blow-by, or thread damage. Follow the recommended torque specifications carefully. Over or under-tightening can also cause severe damage to engine or spark plug
Note: Use only AC Delco spark plugs. Do NOT use Bosch plugs!
