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 Internally Mounted Ignition Coil:

  1. After testing the coil, remove the coil screws and lift the coil out of the distributor cap. Use a needle nose pliers to grab the tach and battery lead clips from the cap connector.

  2. Lift out the rubber insulator and the old carbon button and spring.

  3. Clean the distributor cap cavity and inspect the distributor cap for cracks and carbon tracks. If found, replace the distributor cap and rotor.

  4. Install the new carbon button and spring. Coat the new rubber insulator with dielectric tune-up grease and install into the cap.

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

  6. Install the new coil into the cap making sure the two leads are secured properly into the cap connector. Install and tighten the coil screws.

  7. Reinstall the coil cover.

  8. Reinstall the distributor cap onto the distributor and tighten the four quarter turn screws.

  9. Reconnect the coil primary, tach and battery connectors to the cap.

  10. Reinstall the ignition wire set retainer. A small screwdriver may aid in fastening the clips.

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

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