Finally got around to flushing and replacing the green in my Cummins this fall. It'* going to stay there for a good while. I wasn't aware of they made enviro friendly stuff.

A friend of mine has an E85-capable car, and it can run Everclear as fuel. I wouldn't recommend running alcohol as a coolant fluid because it evaporates sooner than water.

We use to soak coffee beans overnight and strain it and mix with half and half or blend in ice cream. Tasty way to become near comatose....... Back ON TOPIC.... Alcohol as coolant was discontinued when pressurized systems evolved. Using alcohol as a coolant doesn't give you the temperature spread or efficiently needed for a pressurized system. Also there is the flammability issue. hehehe. Never do a flaming shot of it. I have seen it go badly more than once.
