Just had a cooling system flush done by a radiator shop, on a car that had some gooey coolant passages.
It came back clean enough to eat off of. Man, I'd love to know what they use. (yes, I asked, and no they wouldn't be specific)
So what does everyone here like to use? The strongest stuff I've used is the prestone heavy-duty 2-part system that uses caustic soda (I think?). But it never worked as well as the radiator shop's results.
I perused the forums and found references to vinegar, coca-cola, phosphoric acid......
