How to Replace Spark Plug Wires 2009-14 Cadillac Escalade

First you're gonna do is disconnect the spark plug wire from the spark plug. Just grab a hold of it, give it a twist, pull it. Disconnect from the coil same way. Twist and pull. You're gonna keep this heat shield. Just pull it. Set it aside. 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? Then, line up the angle to the coil. Now, just repeat the procedure to the other seven cylinders.
