we used to use waterwetter and water only in the race car and I think it worked great. I used in my street cars added to the prestone. never had any trouble with aluminum with it. there is some other stuff that a friend has used that you do not mix with water. it is expensive so most people will drain it and filter and reuse if they have to open the system for service. he seems to think it works great and supposedly you cannot effectivly get it hot enough to boil it bob
