What kind of anti-seize to use on spark plugs?
The Correct Answer. Virtually all spark plugs now feature a special anti-seizure nickel or zinc-chromate shell plating. Basically, you can think of the plating as a replacement of thread compound or copper slip.
What kind of grease do you put on spark plug boots?
Dielectric grease
Dielectric grease is often used to seal the connection between spark plugs and spark plug wires. Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion.
Should you put anything on spark plug threads?
Should you apply anti-seize on spark plug threads? No. Most spark plugs have either a zinc or nickel plating that prevents the threads from seizing in the cylinder head. That’s different from decades ago when spark plugs didn’t have any coating and could seize in the cylinder head, making removal tough.
Should you use anti seize grease on spark plugs?
NGK spark plugs are installed at the factory dry, without lubrication or anti-seize. Metal shell stretch changes the heat rating of the spark plug and can result in serious engine damage caused by pre-ignition. Do not use anti-seize or lubricant on NGK spark plugs. It is completely unnecessary and can be detrimental.
Can I use lithium grease on spark plugs?
The grease that should be applied is white lithium grease. Dielectric grease is often used to seal the connection between spark plugs and spark plug wires. Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion.
Can you put anti seize on spark plugs?
Anti-seize can act as a lubricant, altering torque values up to 20 percent, increasing the risk of spark plug thread breakage and/or metal shell stretch. Do not use anti-seize or lubricant on NGK spark plugs.
Should I use anti seize on spark plugs in aluminum heads?
The nickel coating on most modern spark plugs provide added protection from seizing in aluminum cylinder heads and has made anti-seize less important in spark plug installations. Anti-seize can alter the tightening torque up to 20%, increasing the risk of breakage.
Is dielectric grease the same as anti seize?
No, they are not the same thing. Dielectric grease is a moisture barrier grease for electrical connections. Anti Seize is a grease compound (there are numerous variations) used to prevent assemblies from seizing to allow disassembly at some point in the future.
Is there a grease that conducts electricity?
The 846 Carbon Conductive Grease is an electrically conductive silicone grease for improving electrical connections between sliding surfaces and parts.
Can I use anti-seize on spark plugs?
Is dielectric grease necessary for spark plugs?
Most commonly applied on spark plug boots, lightbulbs, and battery terminals, dielectric grease is, in theory, a protectant like car wax. It’s not required, but it could help extend and maintain the life and quality of your vehicle and its parts.
