Step-by-Step Instructions
1. Locate the Ignition Coil
Open the hood and locate the ignition coils. They are usually mounted on top of the engine and connected to the spark plugs.
2. Disconnect the Ignition Coil
Use a socket wrench to loosen the bolt that secures the ignition coil to the engine. Then, gently pull the ignition coil straight up to disconnect it from the spark plug.
3. Remove the Spark Plug
If the spark plug is still in place, use a spark plug wrench to remove it. Be careful not to overtighten or loosen the spark plug.
4. Apply Dielectric Grease
Apply a small amount of dielectric grease to the boot of the new ignition coil. This will help prevent electrical arcing and ensure a good connection.
5. Install the New Ignition Coil
Insert the new ignition coil into the spark plug hole and push it down until it clicks into place. Tighten the bolt that secures the ignition coil to the engine.
6. Replace the Spark Plug
If you removed the spark plug, screw it back into the engine and tighten it using a spark plug wrench.
7. Reconnect the Ignition Coil
Plug the ignition coil connector back into the spark plug and tighten the bolt.
8. Reconnect the Battery
Reconnect the battery and start your engine. If the engine starts and runs smoothly, the ignition coil replacement was successful.
