How to Change Spark Plugs

By Stephan Marking

What exactly are spark plugs, what do they do, and why and when do they need to be changed? Here are a few questions that when through my mind when I was told that I needed to have my spark plugs changed. Because I understand not everyone is well versed in the answers to these questions, I've put together what I thought was important to know when it comes to spark plugs.

Spark plugs are the keys to igniting your engine. They are what carry the spark to the engine and fuel, which gives your vehicle the kick that it needs to start.

If you want to know when you should change your spark plugs it might be smart to start by opening and reading your vehicles manufacturing manual. This is a great guide to help you maintain your vehicle in the best possible condition. Many people follow this guide to help them know when they need to change their vehicles spark plugs.

It might not be the smartest thing to overuse your spark plugs. It may seem annoying to follow the manual on when exactly to change them but it is the smartest thing to do. You will begin to feel a rough idle or loss of energy and performance the longer you wait to change your spark plugs.

To find out other reasons why you may need to change your spark plugs, you might have to turn to a local professional. These reasons are usually because they are worn, have bad wires or may be fouled. To really spot these you would have to watch the cylinders firing patters for each one.

We all understand that it isn't smart to overuse anything, especially when it comes to your transportation, but sometimes we are tempted to overlook overusing small things such as spark plugs. The problem with this is now your car will have to overwork to fire up the appropriate voltage to spark and start your engine.

If you are having difficulty starting your car, if it cranks but wont turn over, the first thing you want to do is double check your spark plugs. If you find that they are wearing out then it is time to change them. Many people choose to change them themselves, but some still like to bring it in first to a mechanic to make sure that it really is the spark plugs that are the problem.

Sometimes the problem with your spark plugs is that they simply need to be tightened. This may sounds easy but it is best to be careful while doing this. Make sure that you are checking the manual to make sure that the spark plugs fit the requirements for your car as outlined appropriately. - 29952
