A quick simple explanation of how to change spark plugs in a 2005 or later Chevrolet Trailblazer.
You don't need to be super handy to do this, and it will save you money!
* The only slightly difficult part is the removing the wire harness to get at the forward most spark plug. You just have to twist the white plastic piece so it slides into the black square hole and it will twist itself out. Then, you can remove the entire white piece by unscrewing it after the harness has been removed.
@pillbill35 check out my video, it's a bit longer but explains a lot more then this does

Saw your link. Nice work! You should be a member at GMT Nation dot com, where all the former trailvoy staff and over 500 active members moved to a couple of months ago. Trailvoy is owned by a Canadian corporation who just buys up automotive sites to increase the number of people they can push ads at. The community has left the building......

Thanks for posting this.
FYI on this fix "engine coolant level not high" I think it was error code 215. I replaced the themostat and it fixed the problem. Themostat is a bear to get to and cost $25. I got to it by removing the dirver side wheel and when thru the fender well. Not like the old days when it was on top but now on the 2005 its on bottom between air compressor and alternator.
