I was thinking about adding a coolant filter the bronco since everything , but , the HC is new. There is a pipe plug in the top of my thermostat housing that looks like 3/8". I was going to tap into it and possibly into the line going from the fill cap to the degas bottle. Would this work? The overflow tank on my cooling system doesnt have a radiator cap style lid on it. So would it just pump coolant into the bottle until overflows or would it cycle back into the radiator?
