Removal & Installation



  1. Remove the five-pin harness connector from the ignition coil pack.
  2.  
  3. Using a paint marker or other means, mark each spark plug wire so they can be installed in their proper locations upon coil installation.
  4.  
  5. Once the spark plugs are marked, remove them from the coil pack. When removing the wires, make sure to pull on the boots, not the wires themselves, as they may be damaged.
  6.  
  7. Remove the four bolts that secure the coil pack to the cylinder head. Make sure to hold the coil pack when removing the bolts.
  8.  

To install:

  1. Clean the dielectric grease from the coil pack mounting surface on the cylinder head. If installing the old coil, make sure to clean the grease from the coil pack also.
  2.  
  3. Apply an even coat of dielectric grease to the coil pack mounting surface on the cylinder head.
  4.  
  5. Position the coil pack, and insert the mounting bolts. Finger-tighten the bolts to hold the coil pack in place.
  6.  
  7. Using a torque wrench, tighten the coil pack-to-cylinder head bolts to 7 ft. lbs. (10 Nm).
  8.  
  9. Place a small amount of dielectric grease on each spark plug wire terminal, and install the spark plug boots in the proper order. If a new coil pack is being is installed, note the marks on the old coil pack, using them as a guide to install the spark plug wires on the new coil pack.

Testing

Fig. Ignition coil harness connector identification


WARNING
Testing the ignition system components requires the use of a high impedance digital volt/ohm meter (DVOM) and an LED test light such as Tool No. VAG 1527. A standard analog voltmeter or a standard incandescent 12-volt test light will cause damage to the system's components.

Resistance Check

The secondary resistance of the coil packs on the 2.8L V6 engines can be checked. Because of their internal circuitry, the 1.8L and VR6 coils cannot be checked using conventional test equipment.

2.8L V6 (Afc) Engine
  1. Make sure the ignition is in the OFF position.
  2.  
  3. Disconnect the spark plug wires from the ignition coil pack.
  4.  
  5. Using a suitable digital ohmmeter, measure the resistance for the coil pack between the opposing plug wire connections for each of the coil's paired connections.
  6.  
  7. If the resistance is between 9,000-14,000 ohms, the secondary circuit of the coil is OK.
  8.

Fig. The secondary resistance is measured between the opposing plug wire connections

2.8L V6 5 Valve (Aha) Engine
  1. Make sure the ignition is in the OFF position.
  2.  
  3. Disconnect the spark plug connectors from the spark plugs.
  4.  
  5. Using a suitable digital ohmmeter, measure the resistance at the spark plug connectors between the opposing connections for each of the paired ignition coils.
  6.  
  7. The combined resistance should be 18,000-25,000 ohms.
  8.  
  9. Next, remove the ignition cables from the coils and check the resistance of each of the six cable and connector combinations.
  10.  
  11. The resistance should be 4,000-6,000 ohms.
  12.  
  13. Measure the resistance for the coil pack between the opposing plug wire connections for each of the coil's paired connections.
  14.  
  15. The resistance should be between 8,000-14,000 ohms for the secondary circuit of the coil.
  16.  
  17. If the resistance is within specification for the measured component, the secondary circuit of the coil and wire assemblies are okay.
  18.

Signal Check

This test confirms that the ECM is sending an activation signal to the coils for firing the spark plugs.


NOTE
This test requires the use of a LED test light. Do NOT use an incandescent test light; the current required to illuminate the lamp can damage the ECM.

  1. Remove the fuel pump fuse to prevent the cylinders from filling with fuel while the engine is being cranked.
  2.

  6.  
  7. Turn the ignition switch ON and crank the engine.
  8.  
  9. While the engine is cranking, the LED test light should flash. This indicates that a signal is being sent to the power stage inside the coil.
  10.  
  11. Turn the ignition switch OFF and reconnect the test leads to terminals 3 and 5.
  12.  
  13. Again, turn the ignition switch ON crank the engine. Verify that the LED flashes.
  14.  
  15. Turn the ignition switch OFF and reconnect the test leads to terminals 4 and 5.
  16.  
  17. Crank the engine with the ignition switch once again, and verify that the LED flashes.
  18.  
  19. If the LED does not flash, this indicates that a signal is not being sent to the coil. Causes include faulty wiring, or problems with the crankshaft position sensor and/or ECM. Refer to Section 4 for more information.
  20.  
  21. Turn the ignition switch OFF and plug the five-pin harness connector into the coil pack.
