How to: Check your Spark Plugs
One of the most important aspects of your car’s engine is its spark plugs. These small electrodes give the engine the power needed to make your engine run and move your car down the road. But, they need to be changed out from time to time. So how do we know when this needs to occur? Here is a quick how-to guide to check your spark plugs.
Spark plugs are a main part of your engine and provide its ability to function. DO NOT run your engine while checking your spark plugs as it will not only cause damage to the engine, but could also harm you in the process. If your engine was running, let it cool down before doing this as both the engine and spark plugs get extremely hot.
Now, let’s get started.
Socket Wrench, Socket, and Extender
- Get a socket wrench and a socket that fits the spark plugs (there are special sockets meant to accomplish this task that have padding in them to protect the porcelain part of the spark plug). You can also use a socket wrench extender, if you happen to have one, as it will make removal easier.
Spark Plug Wire
Now, if any of your spark plugs are damaged they can be easily replaced by looking at your owner’s manual and finding what spark plugs are the best for your car as well as the gapping that is needed for the electrode.
You may want to seek out your mechanic, if you do not know what you are doing, so they can do the work properly as well as make sure there is nothing else wrong with your car’s engine caused by the bad spark plugs. This will help avoid any unnecessary damage to the engine or having to replace your spark plugs again.
For reference you would want to replace them every 80,000 miles as they are mostly worn by this point.
