- Grasp the spark plug boot and gently rotate it 90 degrees counterclockwise. Pull the spark plug boot and cable away from the spark plug. If necessary, use a spark plug boot removing tool. DO NOT grab or violently pull spark plug cables.
- Apply dielectric grease into the boot area to reduce the chance of exterior tracking on the buttress tower of the spark plug. This grease also promotes a good heat transfer between the spark terminal screw and boot terminal.
- When it comes to replacing your spark plugs, ACDelco offers a full line of Professional, premium aftermarket Spark Plug products. Choose from our Iridium, Double Platinum, RAPIDFIRE Single Platinum, Conventional, Marine, and Outdoor Power Equipment lines depending on your performance needs. Diesel vehicle owners can also get the ACDelco advantage with our high-quality Glow Plugs. ACDelco Professional, premium aftermarket spark plugs fit both GM and non-GM vehicles.
- Use the correct deep socket size to loosen each spark plug one or two turns. NOTE: To remove spark plugs from aluminum heads, allow the engine to cool. The heat of the engine, in combination with a spark plug that is still hot, may cause the spark plug threads to strip the cylinder head upon removal.
- Brush or air blast dirt away from the well areas before removing spark plugs. CAUTION: Use goggles to protect eyes from debris when applying compressed air to spark plug wells.
- Remove each spark plug and place each one in a tray by cylinder number. This will help identify and relate any unusual condition to the cylinder involved.
- 7 Years / Unlimited Miles on parts sold on or after 04/01/18. (Parts Only) Please see ACDelco.com for more details.
