• Q: How to replace the ignition coil for Bank 1 on 2007 Cadillac DTS?

  A: The replacement process for Bank 1 ignition coils starts with the removal of both fuel injector sight shields. When servicing the ignition coil assembly start by disconnecting the engine harness electrical connector from the ignition coil assembly and then remove the fuel injector sight shield studs together with ignition coil assembly bolts before replacing the ignition coil assembly. Individual ignition coil service requires disconnecting its electrical connector while unscrewing the bolt to remove the ignition coil. The installation process requires installing the ignition coil assembly with bolts secured at 10 N.m (89 lb in). Position the fuel injector sight shield studs while tightening them to 10 N.m (89 lb in) before attaching the engine harness electrical connector to the ignition coil assembly. To replace an individual ignition coil you must install the part while using the individual ignition coil bolt to fasten it with 10 N.m (89 lb in) torque before connecting the individual ignition coil electrical connector. Reinstall the fuel injector sight shields as a final step.
