Your car’s engine is what keeps it running smoothly and efficiently. Over time, however, parts of the engine can begin to wear down and cause problems. One common issue is worn-out spark plugs.
Thankfully, changing spark plugs is a relatively easy process that you can do at home with the right tools and knowledge. In this blog post, we’ll walk you through everything you need to know about changing spark plugs, from choosing the right ones for your car to properly installing them. By the end of this post, you’ll be an expert on spark plugs! Let’s get started.
Spark plugs are small devices that deliver an electric spark to the engine’s cylinders, igniting the air-fuel mixture and causing the engine to run. Over time, spark plugs can become fouled with oil, carbon deposits, or other debris, which can cause them to misfire or fail completely. When this happens, it’s time to replace them.
If your spark plugs are beginning to fail, you may notice one or more of the following symptoms:
1. Decreased fuel economy
2. Rough idle
3. Engine misfires
4. loss of power while acceleration
The first step is to consult your owner’s manual or an automotive parts store clerk to find out what type of plug your car uses. Once you know the make and model, you can purchase the correct plugs. Make sure to get a few extras in case you need to replace more than one at a time.
Changing spark plugs is a relatively easy process, but it’s important to follow the instructions in your owner’s manual carefully. In general, you’ll need to:
1. Remove the old plugs using a spark plug wrench or socket
2. Clean the threaded hole in the cylinder head with a wire brush
3. Screw in the new plugs finger-tight until they’re snug
4. Finish tightening the plugs with a wrench or socket (don’t over tighten!)
5. Replace any spark plug boots or wires that are damaged
Most carmakers recommend changing spark plugs every 30,000 to 50,000 miles, but this varies depending on the type of vehicle and driving conditions. If you do a lot of stop-and-go driving in city traffic, for example, you may need to change your plugs more frequently. You can check your owner’s manual for specific recommendations. The cost of changing spark plugs varies depending on the make and model of your vehicle, as well as the type of plugs you need. In general, you can expect to pay anywhere from $50 to $100 for the parts and labor.
Yes, you can change your own spark plugs if you have the right tools and knowledge. We recommend consulting your owner’s manual or an automotive parts store clerk to make sure you get the correct plugs for your car.
If you’re having trouble removing a spark plug, there are a few things you can try:
1. Soak the plug in penetrant oil for a few hours to loosen it up
2. Use a broken spark plug extractor tool to grip the plug and turn it counterclockwise
3. Hammer a piece of pipe or metal into the ground next to the plug, then use the pipe as leverage to twist the plug out
It’s not advisable to drive your car with bad or failing spark plugs. Doing so could damage your engine and lead to costly repairs. If you think your plugs may be going bad, have them checked by a mechanic as soon as possible.
1. Change your oil and filter regularly.
2. Check your spark plugs and replace them if necessary.
3. Inflate your tires to the proper pressure.
4. Keep your windshield clean and replace your wipers if they’re worn out.
5. Clean your headlights and taillights regularly to ensure optimal visibility.
6. Check your car’s fluid levels regularly and top off as necessary.
