How do you Change, Replace, or Install Broken 2000-2005 Buick LeSabre 3.8L Ignition Coil Replacement

Fits Years: 2000, 2001, 2002, 2003, 2004, 2005


Tools required:

  • 7/32 socket/ratchet with extension


Step 1: Open the vehicle's hood.

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 4: You can now lift and remove the ignition coil.

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.

Step 7: Repeat this process for the remaining ignition coils.
