Thank you for posting! If you need more assistance please REPLY otherwise less then perfect feedback from you means I don't get paid.
so there is no outside leak source for the water?
You may be dealing with a head gasket issue that is consuming the water slowly internally and then overheating once level is low
There are a couple ways you can check for head gasket problems depending on your resources. what kind of tools do you have available? what kind of stores are close with automotive parts?
If you do not want to replace the head gasket you can try getting a head gasket seal additive that can be put into the cooling system in hopes of slowing or stopping the water consumption for awhile.
