What You Need to Know About Changing Coils When Replacing Spark Plugs

When changing spark plugs in a vehicle, it is not always necessary to change the coils as well. The coils are responsible for providing the high voltage needed to create the spark that ignites the fuel/air mixture in the cylinders. Depending on the make and model of your vehicle, and the type of ignition system it has, you may be able to get away with only replacing the spark plugs. If you have a traditional distributor-based ignition system, where the coils are mounted separately from the spark plugs, then you will likely not need to replace them when changing spark plugs. However, if your vehicle has a more modern coil-on-plug ignition system, then replacing both the spark plugs and coils is recommended as they are typically mounted together and are often replaced as a set.

When it comes to automobile maintenance, it is important to understand the different components of your vehicle and the function of each one. This is especially true when it comes to spark plugs and coils. Spark plugs are an essential part of your car’s engine, and they need to be replaced regularly in order to keep your vehicle running properly. The ignition coil is also an important component of your engine, and it needs to be checked and changed when necessary. Knowing whether or not you should change the coils when changing spark plugs is important for the efficient functioning of your car.

What are Spark Plugs?

Spark plugs are a key component in an internal combustion engine. They provide the spark that ignites the air/fuel mixture necessary for combustion by converting electrical current into a spark. The spark plugs are threaded into the cylinder head and sealed with a special thread-locking compound. There are several types of spark plugs available on the market today, including conventional type, iridium type, platinum type, double platinum type, silver alloy type, and more. Each type has its own advantages and disadvantages depending on what kind of vehicle you drive.

What is the Function of a Spark Plug?

The main function of a spark plug is to provide an electric current from the ignition coil which creates a spark that ignites the air/fuel mixture in the cylinder and causes combustion. Without this electric current, no combustion would take place and your car wouldn’t be able to move forward or backward. That’s why it’s so important to make sure your spark plugs are in good condition at all times.

Types of Spark Plugs

The three most common types of spark plugs are conventional type, iridium type, and platinum type. Conventional type spark plugs have copper core electrodes which provide good performance but do not last as long as other types; they also require more frequent replacement cycles than other types due to their shorter lifespan. Iridium type spark plugs have iridium metal center electrodes which provide excellent performance but require higher voltage than other types; they also have longer life cycles than other types due to their high durability. Platinum type spark plugs have platinum metal center electrodes which provide excellent performance with low voltage requirements; they also have longer life cycles than other types due to their high durability as well as their ability to resist corrosion from fuels containing ethanol or methanol additives.

How To Change Spark Plugs?

Changing your spark plugs can be done relatively easily if you have some basic knowledge about auto mechanics and tools used for changing them out. First off you will need some preparation before beginning such as gathering all necessary tools such as socket wrench set with various sizes for different size bolts or nuts; gloves; dust mask; safety glasses; oil pan for collecting old parts; shop towels for cleaning up spills or messes; flathead screwdriver for removing clip-on wire connectors from coil packs if needed; anti-seize lubricant (optional); vacuum cleaner (optional); eye protection (optional).
