Done properly, it would be over 2000. More than likely, it was probably the other way around. The excessive pressure that was being introduced into the cooling system, caused the tank to crack. The overheating was a side effect, and may have happened sooner or later, regardless of the tank. The reason the 2 garages told you cannot fix, is it may have been beyond there abilities either by knowledge, or equipment. It can very much be repaired, but you want the right person doing it. A used engine is a possibility, but strongly consider that a used engine can have the same internal condition, and you may not know t until late. Needless to say, this is a somewhat common issue with this engine. To answer your question on how much generically, I would estimate 2500-3500 to repair.
