Waiting to see what you found. Good Luck with this.

 

It looks like whatever the dealer did when I took it in fixed it. I just got back from a week at the beach (this car sat in the garage all week) and found no coolant on the floor when I got back. They did a pressure check and checked tightness etc. I told them I had been smelling coolant occasionally since they did the timing belt and water pump. Maybe they did something else as well, though they didn't say so. There was no charge. Whatever they did, it's fixed and I'm happy.
