Silly question, but I have a 1957 Ford 860 tractor I am slowly fixing up.
The cooling system has pretty obviously been neglected. I replaced the thermostat and rad hoses and installed new Zerex green coolant.
When I had the thermostat housing off, I noticed it was pretty rusty in the housing and block.
I didn't dare use a chemical flush at this point because the radiator is pretty rough and I don't want to open up a leak.
Just wondering if the new Zerex might be able to clean any of the rust on it's own.
I know it's a long shot, I figure even if it does anything slowly , that would be a win.
