    Q:
    How to check and replace the ignition coil pack on Ford Explorer Sport Trac? Posted by Customer
    A:
    Check the ignition coil by first turning off the ignition and disconnecting the electrical connector(s) from the coil. Connect an ohmmeter across the coil positive (+) terminal and each negative (-) terminal to check the primary resistance of the ignition coil. The resistance should be the same for each check. Then, connect an ohmmeter between the secondary terminals of each coil pack. If continuity does not exist, replace the coil. The ignition coil pack(s) contains three separate coils on V6 models and four separate coils on VB models. Each coil is paired with its companion cylinder. Be sure to check resistance across the appropriate secondary terminals for each coil. To replace the ignition coil pack, disconnect the cable from the negative terminal of the battery. Check to see if all the spark plug wires are numbered. If not, clearly label each plug wire with a piece of tape marked to match the numbers listed on the coil terminals. Then disconnect all the spark plug wires by squeezing the locking tabs and twisting while pulling upward. Do not pull on the wires. Disconnect the ignition coil pack electrical connector. Remove the screws that secure the coil pack to the coil mounting bracket. Installation is the reverse of the removal procedure with the following additions: Before installing the spark plug wire connector into the ignition coil, coat the entire interior of the rubber boot with silicone dielectric compound. Insert each spark plug wire into the proper terminal of the ignition coil. Push the wire into the terminal and make sure the boots are fully seated and both locking tabs are engaged properly.To replace the ignition coil and mounting bracket, detach the radio interference capacitor (if equipped) from the coil mounting bracket. On 4.0L pushrod engines, detach the plastic clip that secures the fuel injection wiring harness to the coil mounting bracket. Then remove the bolt holding the air conditioning hose to the intake manifold plenum. Move the air conditioning tube enough to provide working access to the upper coil mounting bracket bolts. Remove the bolts securing the ignition coil mounting bracket to the engine. On 4.0L SOHC engines, the ignition coil mounting bracket is welded to the valve cover, and therefore unnecessary to remove for access to other components. On 5.0L engines, disconnect the hoses and wiring from the EGR vacuum solenoid, then remove the bolts securing the ignition coil mounting bracket to the engine. Installation is the reverse of the removal.
