GMC Troubleshooting Questions? Ask a Mechanic for Answers
That's a big question. What pieces exactly are you trying to figure out? There are a lot of pieces here, I have to assume that you largely have this handled.
To be perfectly honest, the best images I have for you are found on Google. I looked through the factory service manual and the parts catalogs, and I can get any number of exploded views for any part of the engine, but the thing that's going to help you is looking at assembled views.
I Googled "97 6.5L", clicked on images, and found multiple views of OEM engines that will probably tell you much more than I could ever find in a service manual or parts catalog. Your most expedient route would be to simply do that.
You're welcome. If I can get you anything more technical than that, please let me know. I'm eager to help, but Google is your best resource right now.
