Ignition Coil Replacement

Replacing the ignition coil is not very difficult. I highly recommend that the coil be inspected and tested before replacement. This will save you money by ensuring the coil being replaced is actually defective.

Replacing An Externally Mounted Ignition Coil:

  1. After testing the coil, remove the bracket hold-down bolts or screws and remove the coil and bracket from the vehicle.

  2. Loosen the retaining bolts from the coil bracket and remove the coil.

  3. Compare the old and new coil to ensure correct replacement.

  4. Install the new coil into the coil bracket.

  5. Place the coil and bracket into its mounting position and reinstall the hold-down bolts or screws.

  6. Reconnect the primary ignition wires. Place a small amount of dielectric tune-up grease in the coil wire boot and reinstall it into the coil secondary tower.

  7. Remove the tape from the wires.

  8. Connect the negative battery cable to the battery. Start the engine and test drive the vehicle to ensure correct replacement.

NOTE: Inspect the coil wire and spark plug wires at this time. If cracks in the insulation or corrosion on the terminals are noticed, replace them.
