Is it normal for a car with no overflow to dump a bit of antifreeze after a day

The old school way is to run the overflow hose into a bottle wedged down along the radiator on the hose side. Keep a little fluid in the bottle so the radiator can syphon up some juice if needed and keep critters out, but leave most of the bottle empty. Every Mopar I have ever owned has found it's own fluid level in the radiator, mostly about an inch or so above the cooling tubes. If I fill any of my cars up all the way, it'll surely fill the overflow bottle until it gets down to it's "happy" level. I use a 22oz. pop bottle and drill a hole in the cap the size of the overflow hose. Not the prettiest, but I've done this for years and see no reason to change now!!!LOL!!! Good luck with your project, Geof
