I recently noticed rust or brown muddy water in coolant resorvoir and n under radiator cap. So I drain. And now I'm about to do a flush with blue devil 3-1 radiator flush. I took off upper radiator hose and saw like a metal chunk. Is this bad?? I was going to replace thermostat too. Should I remove and replace thermostat after I do the flush with radiator cleaner. The original thermostat and hoses and radiator on this car. 1993
