Q: How to remove and replace the ignition coil pack in a Saturn Vue?
A: Four-cylinder models require the removal of the Ignition Control Module from the top of the coil pack. This involves removing the four mounting bolts and pulling the module from the spark plugs and valve cover. To detach the Ignition coil pack, remove these four bolts and pull the coil pack straight up. The cover can be removed by taking out the three screws. If replacing the ignition coil pack, remove the four boots from the coil pack and inspect them for cracks, tears and deterioration, replacing them as necessary. For 2002 and 2003 V6 models, remove the intake manifold, which can be left in the engine compartment as long as there is access to the coil packs. Disconnect the wiring harness from the coil pack(s) and remove the two mounting bolts. The coil pack can then be removed. If the module is difficult to remove, bolts can be screwed into it for more leverage to aid in wiggling it free. The gasket should also be removed. For 2004 and later V6 models, start by removing the engine cover. Disconnect the electrical connector and mounting bolt from the ignition coil. On 3.5L V6 models, press the tab to disconnect the wiring, then remove the mounting screw. The ignition coil can then be removed from the spark plug. For all models, apply a little silicone dielectric compound to the inside of each boot before installing it. Installation is the reverse of removal.
