Has anyone ever heard of Four Seasons heater cores? If so, are they any good? I was just thinking that since I am changing the coolant type, rather than flush the heater core, replace it, since they are not the greatest to begin with and the one in there is almost 9 years old... If no one has heard of them, what is the best one to get?
