Can I Change My Own Spark Plugs?
If you are mechanically inclined, you can certainly change your own spark plugs. Though, there are a few things to watch out for if you have never changed a set of plugs before. Making even a minor mistake while changing your spark plugs on your own could lead to serious engine damage.
Tips For Changing Spark Plugs
First, it’s important to ask yourself “What spark plugs do I need for my car?” Don’t simply choose the least expensive option. Check your owner’s manual to find out which type of spark plug to install.
Using the right tools can make the task of replacing spark plugs much easier. You may need a number of different tools to complete this job, including a ratchet, spark plug socket, ratchet extension, universal joint extension, and gapping tool. Keep these tools nearby so you can easily access them while replacing your spark plugs.
You must be cautious to not allow dirt or debris to fall into the spark plug well. If dirt or debris gets into the spark plug well, it could make its way into the engine, where it could cause serious damage.
You should inspect your old spark plugs for unusual wear, and be sure you are installing the right-sized spark plugs for your vehicle. If you install the wrong size, the tips of each spark plug could make contact with the pistons inside the engine, which can cause extensive damage.
Additionally, care must be taken not to cross-thread spark plugs, and a torque wrench should always be used, so your new set of spark plugs are torqued as instructed by your owner’s manual.
Make sure the engine is cool before you start the process of removing and replacing the worn spark plugs. A warm or hot engine could damage the threads.
You will also need to check the spark plug gap if the spark plugs are not already pre-gapped. Use a gapping tool or feeler gauge to measure the spark plug gap and adjust it if needed.
Replacing spark plugs is a doable DIY project for many vehicles, but it’s easy to make a costly mistake if you aren’t 100% sure of what you’re doing.
How Much Does It Cost to Replace Spark Plugs?
A lot can go wrong during a DIY spark plug replacement, which is why it’s recommended to let a professional replace your spark plugs instead of trying to handle the task on your own.
The cost of a spark plug replacement will vary depending on several factors, including the type of vehicle you drive. Some vehicles require more expensive spark plugs than others, and some vehicles might have spark plugs that are more difficult to access. These are some of the factors that can increase the overall cost of repairs.
