You think a quarter gallon aluminum brightener to 3/4 water is a good mix?

How long ago did you change the radiator? For us, it didn't take very long for the buildup to knock out the heat exchange efficiency, but these machines were also putting in 8-10hr+ days in the dirt. I would assume that a new rad should've changed something if it were in fact compromised.

- Yea, I think you could start there and see what it does. It should begin working fairly quickly. Maybe concentrate on a small area just to see if any residue comes off. Should be a visible difference if anything is baked on.

*BTW, was the system properly filled with coolant after the radiator replacement? Was a vacuum pulled? Possibly some air hanging around if not...
