To install:
  1. Position the ignition coil assembly to the engine. Install the mounting bolts, then tighten to 15-22 ft. lbs. (20-30 Nm).
  2.  
  3. Connect the spark plug wires to the proper coils, as tagged during removal.
  4.  
  5. Attach the coil electrical connectors.
  6.  
  7. Carefully lower the vehicle, then connect the negative battery cable.

2.0L (VIN 1 and H), 2.8L (VIN W) and 3.1L (VIN T) Engines

See Figures 2 and 3

On 3.1L engines, an "Idle Learn" procedure must be performed which requires the use of a scan tool. You may wish to have the coil(s) replaced at a proper service facility.

  1. Disconnect the negative battery cable.
  2.  
  3. Detach the electrical wires from the ignition coil assembly.
  4.  
  5. Tag and disconnect the spark plug wires from the assembly.
  6.  
  7. Unfasten the mounting bolts, then remove the assembly from the engine.
  8.  

On the 2.8L and 3.1L engines, with the coil pack removed, each coil can be removed and the ignition module can be removed as well.

To install:
  1. Position the ignition coil assembly on the engine. Install the mounting bolts, then tighten to 19 ft. lbs. (25 Nm) for the 2.8L and 3.1L engines. For the 2.0L (VIN 1) engine, tighten to 89 inch lbs. (10 Nm).
  2.  
  3. Attach the plug wires to the proper coils, as tagged during removal.
  4.  
  5. Fasten the ignition coil assembly wiring.
  6.  
  7. Connect the negative battery cable.
  8.  

On the 3.1L engine, this test must be done before the engine is started and requires the use of a Tech 1®, or equivalent, scan tool.

  1. If equipped with the 3.1L engine, perform the idle learn procedure to allow the ECM/PCM memory to be updated with the correct IAC valve pintle position and provide for a stable idle speed.
    1. Install an appropriate scan tool.
    2.  
    3. Turn the ignition to the ON position, engine not running.
    4.  
    5. Select IAC SYSTEM , then IDLE LEARN in the MISC TEST mode.
    6.  
    7. Place the transaxle in park or neutral, as applicable.
    8.  
    9. Proceed with idle learn as directed by the scan tool.
