2000 BB TC1000, 5.9C.
I have solved the mystery but just for fun let's see what you guys say.
Returned from a short trip with a large elev. gain, and upon shutting off and debusing, I see a puddle on the ground.
The puddle is small and I look up to see drops running down the side of the radiator.
I touch the coolant and it's only warm yet the engine is at full op. temp of 190f.
It's never puked any coolant ever and it never has overheated OR used any coolant including now. Of course with 25 or so gallons, a small leak would not create a low level for a while.
The leak subsides as the system cools.
Estimated loss=1 cup, (very little).
As I said I have solved the mystery, any ideas?
