What are Spark Plugs?

Spark plugs are special kinds of plugs that are used in order to create a spark. This spark is necessary in order to ignite the air/fuel mixture inside of the engine. Spark plugs have a very important job, and they need to be replaced every so often in order to ensure that they are working properly.

When Should Spark Plugs be Replaced?

Spark plugs typically need to be replaced every 20,000-40,000 miles. However, this number can vary depending on the make and model of your vehicle. It’s always best to consult your owner’s manual in order to get an accurate estimate for how often you should replace your spark plugs.

Signs You Need to Check Your Spark Plugs

There are several signs that you might need to check or replace your spark plugs. These include:

• Your engine is misfiring. If this happens, it means that the spark plugs are not firing correctly.
• Your vehicle is experiencing reduced fuel economy. This could be due to a number of different factors, but it’s worth checking the spark plugs if you notice a sudden decrease in mileage.
• You notice a decrease in engine power. This can be caused by a number of different things, but worn-out spark plugs can definitely be a factor.
• Your vehicle is hard to start. If the engine is having trouble starting, it could be because the spark plugs are worn out.
• Your vehicle’s engine sounds rough. This is another sign that the spark plugs are not firing correctly.

If you notice any of these symptoms, then it’s time to take a look at your spark plugs.

How to Check Your Spark Plugs

If you’re unsure of how to check your spark plugs, don’t worry! It’s a relatively simple process that anyone can do. All you need is a ratchet and a spark plug socket.

First, locate the spark plugs on your vehicle. They are typically located near the top of the engine. Once you’ve found them, use the ratchet and spark plug socket to remove each one.

Once you have removed the spark plugs, take a close look at them. If they are damaged or worn down, then it’s time to replace them. However, if they look fine, then you can just clean them and put them back in.

How to Replace Your Spark Plugs

If you need to replace your spark plugs, the process is relatively simple. Just follow these steps:

• Remove the old spark plugs using a ratchet and spark plug socket.
• Clean the area around the spark plug hole. This will help prevent debris from getting into the engine.
• Thread the new spark plugs into the holes. Be sure not to cross-thread them!
• Tighten the spark plugs until they are snug. Be careful not to over-tighten them.
• Reattach any wires or covers that you removed in order to access the spark plugs.
• Start the engine and listen for any strange noises. If everything sounds normal, then you’re all set!

By following these steps, you can easily replace your spark plugs on your own. However, if you’re not confident in your ability to do so, it’s always best to consult a professional at Scott’s Auto.
