    Q:
    How to remove and install an Ignition Coil on Chevrolet Malibu? Posted by Twyla W.
    A:
    Disconnect the cable from the negative terminal of the battery. Remove the engine cover. Disconnect the electrical connector from the coil. Detach the coil harness fasteners from the valve cover and position the harness to the side. Remove the ignition coil mounting fasteners. Pull up and twist to remove the coil. Installation is the reverse of removal. Apply a little silicone dielectric compound lo the inside of the coil boot before installing it. Installation is reverse of removal.
