    1994 cadillac seville Spark plug change

    So i'm about to change the spark plugs on my 1994 cadillac seville. I know there's a tech tips section that has a detailed instructions, but I can't seem to find it. Can anyone post a link to this specific page, or give idiot proof instructions how to get there?

    Nothing much to post - pull the plug wire, remove the old plug, re-install the new plug. I use a little no seize on the threads. I think you may find it's worth the time invested to unbolt the ignition module and coil pack off the right bank - it will give you some more access to those plugs

    DEFINITELY use "anti-seize" on the threads, and also get some "dielectric grease" to put on the inside of the spark plug wire boots.......it will help prevent "arcing"

    Good advice, but be advised that there is a mounting bolt on the back side of the ICM that you'll need to use the Braille method to remove and reinstall.

    Aight cool, I didn't think there was anything more to it than that. Just figured I would double check so I didn't run into any suprises.

    Use this to make sure all the plug wires are connected correctly - it's important - Google "waste spark ignition" to find out why.

    Cool, thanks sub, I found that diagram the other day in another thread, but I didn't save the link. Saved me some time searching for it again.
