Does anybody know exactly how the cap on the coolant reserve tank works? Yesterday I saw it leaked a little out, probably because I may have had a little too much coolant in the system. But I heard someone saying that once it vents, it has to be replaced.
I figured it works like any other cap, it vents whenever the pressure goes beyond normal, and doesn't mean it's fried?? I know the thing's only 9 bucks, but damn, I just bought this one just before winter.
