Sounds to me like the latest trampers gimmick - powdered water. Just pour powder into glass and add water.

John, I don't know about evanscool, but I use hyper cool in my 39 and it works great. I have had no issues thus far with it

Heres a pretty good article regarding the 'waterless coolants'.

Jeff- thanks for posting that article. It helped me make up my mind not to try waterless coolant.

Your welcome!
I did some research in considering it myself some time back, and also decided against it.

Plus, it is a glycol. It IS going to pick up some water regardless, and you will get the corrosion problems, etc as it decomposes into acids over time and combines with water.

John,

In the 1950's I worked one summer at an electric power dam in the state of Washington, a very cold place in the winter. In those days, it was customary to use water in one's cooling system in the summer, and a mixture of water and either ethylene glycol, or alcohol, in the winter. However, some of the fellows who worked there year round helped themselves to some of the transformer oil that was freely available, and said that it worked well.

Several years later, I decided to economize on antifreeze so I filled my '46 Super Six with heating oil. Sadly, this opened a slight leak in my heater, and the car stank! I removed the heating oil ...

Per,

Which dam did you work at?

Guess that's like the time after all the beer was drank and a hose sprung a leak and after us 3 guys fixed it we needed liquid to fill the radiator.....
and well ....it didn't smell to great either!!
Those were the days.

Tim,

I worked at the Grand Coulee Dam the summer of 1957. I traveled from the east coast there and back with a friend in his 1939 Packard hearse.

Per,
Yes, that's the big one north of where I live (Tricities). With so many dams on the Columbia, wondered which one. -Tim
