How to Install New Spark Plugs?

What do Spark Plugs do in a Car?

The spark plug is basically a small electric gadget that is plugged into your engine's cylinder head, where it "sparks" to ignite the fuel. The spark plug is attached to the ignition coil through which it creates high voltage needed to spark the fuel and generate combustion within your engine. Faulty spark plugs mean no spark to ignite the fuel, therefore no combustion.

How To Install New Spark Plugs?

Buy a perfect set of replacement plugs: You can either refer to your vehicle's owner manual or an auto parts related booklet at the auto parts store that have all the vital information about your vehicle's make and model and the year of manufacture. There is an array of different combinations of spark plugs and measurements, made of metals like platinum, yttrium, and iridium, etc. Spark plugs made of precious metals like platinum and iridium are slightly expensive than ones made of lesser metals like copper since they have high melting points and can survive up to 100,000 miles. So choose wisely!

Clean the area around the threads before installing new spark plugs: When you are inserting new spark plugs, take a good look at the wires for any visible signs of wear and tear and clean up the area around the wire terminal carefully and with caution. You can use a thin wire brush or compressed air to clean the area around the wire connection and make sure the port is clean. Replace the wires if necessary.

Plug new spark plugs and secure them with a ratchet: With the spark plug socket, unscrew each plug from the engine and replace each with a brand new spark plug. Tighten the plugs a bit, but don't over tighten them too much as you can easily strip the thread on the head of the engine and those repairs are way too costly and time-consuming.

Lubricate the plugs prior to installing: Put a small amount of anti-seize lubricant on the plug threads if you are plugging them in an aluminum engine. This lubricant will prevent any sort of reaction between dissimilar metals. You can also apply a small amount of dielectric silicone compound on the inside of the spark plug wire boot so that they can be easily removed in the future.
