NOTE: When replacing ignition coils, it's usually a good idea to replace ALL OF THEM in the same installation. However, you will want to replace them ONE AT A TIME during the process. Also, be sure that the sparkplug wires attach to the SAME sparkplugs they were originally attached to!
Step 2: Disconnect the sparkplug wires (2) from the ignition coil.
Step 3: Loosen and remove the 7/32 mounting bolts (2) that secure the ignition coil to the engine.

Step 5: Mount the new ignition coil by tightening the 7/32 mounting bolts (2).
Step 6: Attach the sparkplug wires (2) to the new ignition coil.
