Ok i need to ask, what does the overfill do besides catch the overflow when she gets hot? Mine just goes on the ground. Whats the need to catch it?

Thanks

It’s just an environmentally conscious decision. I just stuff an old coolant jug in the corner beside my battery and run the overflow into it. Not a show truck set up, but it does the job.

And also to keep from adding coolant as often.

Yep.. The radiator cap creates pressure inside the radiator. As the radiator cools, the is pressure reduced. This creates a suction pulling in coolant from the overflow keeping the radiator full.
