Where do I put dielectric grease on a coil pack?

It is a preferred grease for automotive ignition applications because ignition systems use rubber boots to keep the spark plugs and spark plug wires away from moisture Silicone dielectric grease is used on the bottom of the inside of the ignition coil boot where the spark plug meets the ignition coil.

Are coil packs hard to change?

Weaken windings inside a coil eventually break, creating resistance for the spark going through them. Unfortunately, you cannot replace the windings, but you can replace the faulty coil, or coil pack.

How many spark plugs are in a GM 2.2L?

Ignition System: As you’re already aware, the ignition system on the GM 2.2L is composed of an ignition module, two ignition coils (that feed two cylinders with spark simultaneously), 4 spark plug wires, and 4 spark plugs. If any one of these goes bad (and they do), then you’ll end up with a misfire condition.
