Disappearing coolant

Disappearing coolant
Hi everyone.
My CUCV keep losing coolant and I don’t know where. It had some radiator issues a while back but didn’t seem too serious.
Here’s the rundown.
The radiator had a slight split seam a while back so slight I though it was a small pinhole. I kept running it but never got too low on water - it was a small leak and I kept the proper mixture on hand and kept it topped-off. Every now and then I’d get a low coolant light and I fill it up. Sometimes I noticed if using the heater after a while the heat quits and blows cold air: a sure sign of low coolant and do the same.
Then one day it blew and I limped the two miles back to the house. Pulled the radiator and had fixed. Replaces hoses and flushed the system. I never thought I overheated it because of no shutdowns or other heat related issues. However I have noticed since then if I’m driving it’ll lose an overflow reservoir of coolant every few days and get the no-heat heater bit again.
I have let it running fully serviced and warm but have seen no leaks or puddles underneath. There is no water/oil mixing signs and no steam or sweet smell coming from the tailpipe (as sometime you can see the billowing cloud and sweet smell from some car on the road). But I don’t know if there are other observable signs.
So I have:

So I have:
- Radiator trouble but fixed unit
- Never thought it got too hot
- Replaces hoses
- Not seen obvious leaks, water-in-oil signs, or no steam clouds out of tail pipe
- Have not replaced thermostat or radiator cap
- And overflow tank (where I service it) runs out every few days.
