Chevrolet Tracker Spark Plugs

January 25, 2008 2:02 PM

Changing sparkplugs: I have a 2003 Chevrolet Tracker, with an unusual ignition coil setup, and I want to learn how to remove the coils and access my plugs. (Pictures inside)

Typically spark plugs have a boot with a cable coming out of them, but my car has a different setup that is confusing me. On the top of my engine are 4 caps that seem to be covering the spark plugs. I wanted to know if I can just pull them off, or if there are special steps I have to take.

Also, I'm concerned about the clips on the side of the caps -- do I remove those first or do I just pull the whole assembly off? If anyone has changed their plugs on a Tracker, I'd be most grateful for your advice!

I happen to have a 2003 Tracker service manual handy. It says to just disconnect the electrical connector, remove the bolt and the ignition coil, then remove the plug. Give me a minute and I'll copy the relevant pages.

These are awesome. Thank you so much! Where did you get that manual? Did you order it from GMC? I'd like to get a copy myself.

I would guess we probably got it from Helm, but I'm not sure.

For future reference, that kind of ignition system is called coil-on-plug or direct ignition, and is nearly ubiquitous on modern engines.
