The ProMAXX 3.5L Ecoboost and 5.0L Coyote Broken Ignition Coil Hold Down Bolt Repair Kit is designed to repair broken ignition coil hold down bolts without removing and replacing the plastic valve cover. The Ignition Coil Hold Down Bolt jig anchors into the black plastic valve cover, providing ideal, dead-center drilling to remove the broken fastener. Once the fastener is removed, a machine-shop-grade tap cleans the threads and restores them to factory new. The ProView version includes a smartphone-compatible, scoping digital camera that provides quick assessment, easy alignment, and better inspection of the broken bolt.
