Only 2 places for coolant to go. You're leaking it somewhere or you're burning it (head gasket). If you can't visibly see any leaks, you can put dye in the coolant. Another trick is to park on a big piece of clean cardboard overnight and check for spots in the morning. Also, check the oil to see if it is light brown, like creamed coffee. If it is, you got a head gasket problem.
