The radiator should take in air through the overflow tube as the coolant cools/shrinks. If you have a pressure cap, check it. If no pressure cap, suspect a blocked overflow tube. You don't happen to have one of Skips 3# pressure valves, do you?

Thanks 40cpe. I don't have Skips 3# valve. I'll check the cap, it's been there 4 a few years. Thanks again, just never encountered this before. mike

hi mfirth soft hoses could also cause this, if there is no wire spiral inside hoses can you collapse the hoses by hand ? I would refill the coolant, while the engine is running, when warm, put the cap on and check for leaks, see if there is any loss do you have a coolant pressure pump, you can also check the cap with one of these, [ one of the handiest tools ever ] if you do try adding a few lbs to the coolant system and see if you can see any leaks, keep a eye on the gauge and see if it drops, might be a very small leak and it that happens over time, hope this helps, 37Ragtopman
