How to replace the ignition coil for Bank 1 on Cadillac DeVille?

Start by lifting the cam cover's Ignition Coil cover and fuel injector sight shield straight up when they are present to access bank 1's Ignition Coil replacement. You need to examine individual coils by disconnecting the secondary air injection (AIR) electrical connector of the vent solenoid and disconnecting the air check valve. The coil replacement requires disconnecting the wiring harness electrical connector from the targeted coil followed by removal of the retaining bolt before trying to gently remove the Ignition Coil. To perform all coil replacements start by disconnecting the main coil wiring harness at the cam cover followed by removing the coil assembly retaining bolts and studs before removing the Ignition Coil assembly. After coil positioning install the retaining bolts and studs to 10 n.m (89 lb in) while making sure spark plug seals maintain correct placement. The primary coil wiring harness should connect to the cam cover before installing the Ignition Coil into place with spark plug seals in position while tightening the Ignition Coil retaining bolt to 10 n.m (89 lb in). Reconnect both the Ignition Coil electrical connector and the air vent solenoid electrical connector if removed and restore the air check valve assembly if it was previously uninstalled. As the last step reinstall both the Ignition Coil cover to the cam cover when it is equipped and the fuel injector sight shield.
