said by fartness:1. Will I need new bolts when I get my new thermostat housing installed?
Only if the old bolts are badly corroded or break coming out and have to be drilled out. Normally no, you just clean up and reuse the bolts.
said by fartness:2. If so, what is the model number for the bolts?
Model Number is none, However the Part Number is listed there in your image.
said by fartness:3. What is the book time for this job? Appx. cost to install this? Dealer said one hour, which seems cheap. I remember needing a thermostat years back and it cost probably $150 for parts and labor.
One hour like the Dealer said. The Dealer uses book time.
said by fartness:4. Can my coolant be saved? It's new.
It won't require draining all the coolant out of the system, but what you drain out before you take it apart can be reused if you use a clean container to drain the coolant into. Easy as pie, ok?
said by fartness:5. Will the air need to be burped from the coolant?
Always bleed cooling systems when refilling them.
said by fartness:6. Will I need another gasket (8255 part) that is different than the o ring that Amazon considers a gasket? The Amazon picture is accurate with what the housing came with.
Yes, always use new gaskets, it not much money and it is cheap insurance.
