Re: I removed more coolant than will fit back in, why?

There's a tool for that. Pulls vacuum and removes the air. You trap air as the coolant enters in pockets in the block and they have to be released/filled. If you run it and monitor, you're running with hot spots as there's no coolant in those areas.
You can do the same with a radiator pressure leak tester. Just don't pressurize these old radiators more than a few psig.
