Q&A

Dandd, thanks for your concern... I drop it off at the dealer tonight for his mechanic to take a look, (seriously doubt he will return the money). Earlier today I was quoted 2000+ from another mechanic that says that the only reason why there is overflow is because the head is bent, scratched or crack and the probably the water pump also, and basically a new engine, new gaskets, etc...
Due to air and boiling water from the reservoir. I was shock by his quote and telling me that it will need 8 days of labor,etc.. I really don't trust his answers since I left the car there for a couple of hours and all he did was put more water on the reservoir while the car cold and on, and showed me the water shooting up. The car runs fine has lots of power and no scarey noise or rattle on the engine just a woo high pitch sound from the reservoir.
Is he correct and I am screwed!! or could there be another answer... should I try everything else first?
