Last year I put a new copper radiator in from performanceradiator.com. Yesterday I opened the rad cap to look and theres brown gunk coating the fins.
Is this normal or should I get it flushed?
What could cause this after 1 year? Not enough coolant?
BTW I used Prestone's green coolant with carbon-filtered water. The coolant came out looking clean. Car runs fine at 180-185F.
