How to Replace Ignition Coils 2007-18 Cadillac Escalade

First thing you're gonna do is disconnect the spark plug wire from the spark plug. Just grab ahold of it. Give it a twist, and pull it. Disconnect from the coil the same way, twist, and pull. You're gonna keep this heat shield. Just pull it. Set it aside. Two mounting bolts mount the actual coil to the bracket. You have one connector. So, you're gonna take that tab. Lift that tab out. Pull the connector out. 10 millimeter socket. Lift the coil out.

So, to reinstall, just reverse procedure. Line up the bolts. Torque the two mounting bolts to 89 inch-pounds. Double-check. Now, you're gonna reinstall the connector. Line it up. Push it down until you hear it click. Tab's locked. Twist on the new coil wire, spark plug wire, it comes pre-siliconed. Slide your old heat shield over it right to the bottom. I like to put it right on the spark plug until it clicks in. Hear it? And line up the angle to the coil. Now, just repeat the procedure to the other seven cylinders.
