I know this is a really old post, but it's something I'm considering doing to my radiator. Can you tell me if this fix will operate as a 2 way valve? In other words, if run the hose to an overflow tank, will it pull coolant back into the rad if needed? I cannot find any info on these old radiators online, so I'm hoping someone can help me out with this.

Thanks,
Kevin.
