Losing coolant past couple months. From where all could it be losing coolant?

hundreds of places. get a shop to pressure check the system to determine the leak and give you a bid. Roy

Look under vechicle and tell us if there is fluid on the ground after you top it off and approx. location of components above the spot. If you don't see any on the ground, it could be leaking into engine oil which would be another issue entirely.
