yep its normal. our cars are 20+ years old..
Just think if you ran coolant though an engine...poured the used coolant into a container - leave it to sit for anywhere from a couple of hours to couple of months...pour old coolant back into engine..run engine...repeat...change all the coolant every year or two..or five..
How do you think that container would look after 20+ years?
