All I can say is it left the radiator sparkling clean and the dirt, sludge, filth that came out of the cooling system, with this treatment, left the system very clean.
I had no leaks or problems afterwards.
This is an interesting idea. Do you remember what the ratio of Cascade to Hot Water was?
The cooling system on my F150 works fine, but there is some mild scale buildup possibly due to switching from factory green to Zerex G05 or having used tap water at one time. I sometimes get a chill down my spine when I think of the buildup so I'd like to clean it all out.
When I did it I used 1/2 cup of Cascade (try to find the powder with dawn in it, great at degreasing.) Mixed with a gallon of hot distilled water. Just make sure to really flush out the system with distilled to make sure all of the cascade is out. Works like a charm and the rest of the powder you can use in your dishwasher!
