  1. Disconnect the negative battery cable.
  2.  
  3. Detach the 8 or 11-pin harness connector from the coil and module assembly.
  4.  
  5. Remove the ignition assembly-to-camshaft housing attaching bolts.
  6.  
  7. Carefully remove the ignition assembly from the engine.
  8.  

If the spark plug boots present a problem coming off, it may be necessary to use a special removal tool, first twisting and pulling upward on the retainers.

  1. Remove the ignition coil housing-to-cover bolts/screws.
  2.  
  3. Remove the cover from the coil housing.
  4.  
  5. Unplug the coil harness connector from the module.
  6.  
  7. Remove the screws attaching the module to the ignition assembly cover.
  8.  

If the same module is going to be replaced, take care not to remove the grease from the module or coil. If a new module is to be installed, a package of silicone grease will be included with it. This grease aids in preventing the module from overheating.

To install:
  1. Place the module on the ignition cover and install the attaching bolts/screws. Tighten the attaching bolts/screws to 35 inch lbs. (4 Nm).
  2.  
  3. Connect the coil harness connector to the module.
  4.  
  5. Assemble the module cover to the coil housing and install the attaching bolts. Tighten the attaching bolts to 35 inch lbs. (4 Nm).
  6.  
  7. Install the spark plug boots and retainers on the ignition assembly housing secondary terminals.
  8.  

If the boots and retainers are not in place on the housing secondary terminals prior to installing the ignition assembly, damage to the ignition system may result.

  1. Position the ignition assembly to the engine while carefully aligning the boots to the spark plug terminals.
  2.  
  3. Coat the ignition assembly-to-camshaft housing attaching bolts with an approved lubricant and install them into the housing.
  4.  
  5. Tighten the attaching bolts to 16-19 ft. lbs. (22-26 Nm).
  6.  
  7. Attach the harness connector to the ignition coil module assembly.
  8.  
  9. Connect the negative battery cable.
  10.  
  11. Start the engine and check for proper operation and performance.
