How do I change this spark plug on my 2007 Chevy Tahoe?

This pat answer does not help me. I need an answer from someone who has changed this spark plug in a 2007 Chevy Tahoe with the 5.3 liter engin. This pat answer does not help me. I need an answer from someone who has changed this spark plug in a 2007 Chevy Tahoe with the 5.3 liter engin.

I'm sorry if I offened you. I was hoping for some specific steps on what to do, and maybe what not to do. The space is so small I thought maybe I had to remove some engine parts first. You are right that I have never done it before. My concern is that I may struggle and eventually get the old plug out but may not be able to get the new one back in. I can only get one hand in there at a time and after struggling for a bit and cutting up my hand on nearby engin parts I gave up, thinking there must be some special trick that someone could share with me. Also, I have seen some people recommending using an "anti-freeze" compound on the new plug threads . I have never used this before on all the other vehicles I have changed plugs on. I never even heard of it before. Is this something that you use when changing the plugs on your Tahoe? Is this something you feel is necessary. Thank you for your help. I'm sorry if I offened you.
