2gnt Engine Bay Tutorial

[Doug99RS]

I saw a website for a 4g63 engine bay where the author had listed everything under the hood and showed a picture to match the description. So working off the same Idea I did the same thing for the 2gnt. Now this particular vehicle is an automatic but the engine and emissions components are all going to be the same. I'll eventually get some more pictures up of a 5spd 2gnt. Second note is that on some vehicles the components are in different locations such as some of the emissions components. But the component design did not change drastically and if you see what one looks like then you'll be able to find yours.
