No Problem, I understand the frustration.
One thing to do if you haven't yet is pick up a Haynes manual (some prefer Chiltons) on the car. They run about $15 and they're a great investment, and will pay for themselves the first time you do something like a Tstat change yourself instead of paying someone $70 an hour. Those books will walk you through it with steps, pics and all. Then if you want to get more hardcore, buy the shop manual for your year of vehicle, off ebay or something like that.
We can walk you through a tstat change, where do you want us to start? (In other words, how much about your engine, or engines in general, do you know?)
