Anyone have a diagram of the heater hoses on a 96 Trans Am, M6? Also does it have an oil cooler, and where do the lines come from? Im starting from scratch and I'm kinnda lost.

 

Use shbox.com site. It is the best source. Shoe is a VERY valuable member.

Clilck on Drawings/Exploded Views. Yours may be different, but give it a shot.
JMHO

 

If you're looking for the entire hose assembly that goes back to the heater core and all the way up to the front including the aluminum lines and air valves, here's a reference off shoebox's site:heater hose

btw, what exactly are your trying to figure out regarding an oil cooler?

 

There are also diagrams of the oil cooler and lines on my site.
