How To Replace Your Spark Plugs Yourself

How To Replace Your Spark Plugs Yourself

1. Cut Off The Engine And Wait For It To Cool Down

Before replacing the spark plugs, you need to ensure you purchase the right ones for your vehicle. I usually fire up Amazon and filter the selection by the make, model and manufacturing year of my vehicle.

If you overlook this step, it won’t be possible for you to remove the spark plugs from their location without damaging the threads. The cylinder heads are made from aluminum, so their threads can easily get damaged if you aren’t careful. Once you’ve damaged this thread, repairing it will be extremely difficult and it will require an expert to do it.

2, Remove Dirt Around The Spark Plugs

Blow out all dust and debris around the spark plug. You can use an air compressor. Your man goal should be to prevent any dirt particles to fall into the engine, as they can lead to premature wear and various other problems.

3. Check That The Spark Plugs Are Correctly Positioned Before You Start Screwing

If you don’t position spark plugs correctly, they will cross-thread, causing huge problems. I usually wiggle the spark plugs a bit before screwing, just to make sure they are straight. Anyway, start screwing them very slowly and stop at the first sign of resistance. Take a breathe and do it again from the start until you get it right.

4. Replace Spark Plugs One By One

Getting all those wires mixed up is a very easy thing to do. For safety reasons, it’s much better to change your spark plugs one at a time. If your car has a coil-and-plug unit, you’ll be fine either way. In addition, newer models of vehicles won’t allow you to misplace parts. Older cars, however, need more attention.

What Tools You Need To Replace Your Spark Plugs

Changing your spark plugs is easy, provided that you have the right tools. I’ve already mentioned the need for an air compressor that will allow you to blow off dust and debris around the spark plugs before removing them. You’ll also need a spark plug gap tool to adjust the gap between electrodes.

Another must-have is a spark plug socket. This socket features a rubber insert that protects the spark plug during handling.

If your car has a coil-and-plug system, you may have to buy a small socket wrench or a screwdriver to remove them from their positions. Most often than not, these spark plugs are bolted on.
