Good Maintenance Practices - Section 1 - Bullet 1Grasp 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
Good Maintenance Practices - Section 1 - Bullet 4Remove 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.
Good Maintenance Practices - Section 1 - Bullet 5Apply 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.
Approximate Resistor Value3-7.5k ohms
Spark Plug Approximate Resistor Value3000-7500 ohms
Good Maintenance Practices - Section 1 - Bullet 2Brush 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.
Good Maintenance Practices - Section 1 - Bullet 3Use 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.

Signs Of Wear &#38; Troubleshooting - Section 1 - Bullet 1Your engine having trouble starting, hesitating, or cutting out
Faq - Answer 8Yes, ACDelco has marine spark plugs for many applications.
Signs Of Wear &#38; Troubleshooting - Section 1 - HeaderSigns of wear for spark plugs include but are not limited to:
Faq - Answer 7No, cleaning your old spark plugs is not recommended. Dirty, fouled spark plugs may also have broken or chipped insulator tips, worn electrodes, or worn or missing side wires. These conditions severely affect spark plug performance. Replace your dirty, fouled spark plugs with new ACDelco spark plugs.
Faq - Answer 6Yes, pre-ignition can cause serious damage to your engine. Pre-ignition is the ignition of fuel before the actual spark occurs, which causes a rapid temperature rise in the combustion chamber that can damage engine components and melt spark plug electrodes. Causes of pre-ignition include but are not limited to a buildup of deposits that can become incandescent in the combustion chamber, improper installation torque being applied to spark plugs, and having spark plugs with a heat range that is too hot for the engine’s operating condition.
Faq - Answer 5Not always, but you should inspect your spark plug wires for wear when replacing your spark plugs. Refer to your vehicle owner’s manual or contact the manufacturer for more information.
Faq - Answer 4Yes. When ACDelco spark plugs are manufactured, they are pre-gapped to the correct gap specification.
Faq - Answer 3Yes. Diesel engines require glow plugs because diesel engines operate differently than gas engines. ACDelco Professional Glow Plugs are specially designed to give diesel engines the heat they need for their cold starts. Refer to your owner’s manual or contact your vehicle’s manufacturer for more information.
Faq - Answer 2Yes, if it is the scheduled time for spark plug replacement. It is okay to replace one spark plug if it is fouled or damaged prior to scheduled maintenance, provided the source of the damage is found and corrected.
Hex Size (In)16
Faq - Answer 1Yes, this interval depends on what type of spark plug your vehicle requires. Refer to your owner’s manual or contact your vehicle’s manufacturer for more information.

Good Maintenance Practices - Section 1 - HeaderVisually inspect spark plugs for signs of wear. Follow these steps for removing spark plugs for inspection, servicing or replacement:
Good Maintenance Practices - Section 1 - Bullet 6Before installing new spark plugs, use a gap guide to make sure your new spark plugs have the correct gap. NOTE: ACDelco GM OE Iridium Spark Plugs are pre-gapped during manufacturing. Never attempt to gap an ACDelco GM OE Iridium Spark Plug. You could damage the spark plug. Replace any incorrectly gapped ACDelco GM OE Iridium Spark Plugs with plugs that are correctly gapped.
Good Maintenance Practices - Section 1 - Bullet 7Install spark plugs or glow plugs to the proper torque per the manufacturers’ specification.
