The only reason I used that coolant was because I had a bottle of it standing in the cupboard for a while. It actually says: Contains Glysantin Alu protect from BASF. I once read a test of Anti-Freeze in CAR MECHANICS; this one came out about average, probably a trade off for the longer life span 5 years. But the best performing Anti-Freeze was one called '4 Life' which had both good cooling performance and 10 years long life. > While the water from your dehumidifier may have been "distilled", I know > that the catch tank on mine is always developing some sort of growth in > it, so I'm not sure it would be such a good idea either.
