OK this is very odd, when I got home yesterday, the coolant wasn't dripping but I could see 2 drops on the heat shield right above the exhaust, where the coolant had been dripping from. I wiped them off so I can tell if it continues to drip. The coolant level was at the MAX line, I assumed due to heat expansion.

This morning, the heat shield was still dry, and the amazing thing is, the coolant bottle still shows MAX! It had been at MIN yesterday afternoon!

Is there some voodoo magic involved in maintaining the level of the coolant?
