How to change ignition coils Kia / Hyundai
Step 1: Let engine cool down
Make sure the engine has cooled down. We would recommend disconnecting the negative terminal from the battery. Rember to never touch ignition coils or spark plug wires when the engine is running. Ignition coils generate high voltage that can be hazardous and even cause death.
Step 2: Remove the engine cover.
The cover pulls right up. It is held in place with four tabs, pins and there are no screws that you need to worry about.
Step 3: Identify the ignition coil
Locate the faulty ignition coil. Cylinders are numbered from one to four, one starting on the passenger side and cylinder four is on driver's door. If you had a P0301 misfire code that means that cylinder one plug or ignition coil ONE is defective. If you had a P0302 misfire code that means that cylinder TWO plug or ignition coil is defective and so on. Before you remove the spark plug wires, we recommend that you label the wires so that you will be able to connect the wires to the correct ignition coil. Remove the plug wires by squeezing on the lock tabs and pulling up on them until they come off of the coil as shown in the video. Move the wires off to either side of the coil to get them out of the way.
Step 4: Remove ignition coil
The ignition coil is held on with one 10mm bolt. Remove the bolt using the 10 mm sockets and ratchet. You can now pull the coil up and remove it out of the vehicle.
Step 5: Install new ignition coil.
Carefuly place the new ignition coil in making sure it is seated properly on top of the spark plug. Secure it with the bolt using the socket and ratchet. Press the spark plug wires into the ignition coil until you hear it click / lock. If you are replacing all of the coils, make the igntion coil connectors go back into the same coils as before, mean don't change the order of the electrical connectors.
