Gooberbob,
Sorry for the delay in getting back to you but have a new job and haven't been doing much car stuff until today. I got the diagram from GMpartsdirect.com. Go to the catalog and look up the cooling system stuff, like the thermistat. I will give you a listing with the thermistat and their price, below the price there is a button that says "view illustration" that is where the picture came from. I just did a right mouse click and hit "save picture as..." bob's your uncle!
Sparky, where did you get the cooling system component diagram you posted on the Venture forum in the LIM Gasket repair thread on August 28. 2007? (post #321). I need to idnetify some of those numbered components, so I just need the legend that goes with the diagram. Thanks much.
