Today, I filled the coolant agian, and it disapeared after I drove it. I looked down by the overflow tank and what did I see? There was a poudle of coolant about an inch deep, and it was sitting right under the overflow tank, not leaking on the ground. Maybe, just maybe that is where all the coolant is going, so tomorrow I am gettting a new overflow, and will see what happens. Cross your fingers

 

Sweet.

Good luck.
