Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

If you are sure you have no external leaks and you are loosing coolant then that usually means the engine is burning it which usually means you have a seeping head gasket or a problem with the head.. I would start with performing a cooling system pressure test as well as a block test to determine if that is the cause of the loss of coolant.
