If it loses coolant to the point of having to top off again soon have the system pressure checked for a leak. As the hoses and seals get old small amounts of coolant are able to get out and evaporate. Wherever the coolant is seeping out from may not ever appear wet, but a crust will develop there from the evaporated coolant making it easier to spot. Good luck and hope for something simple! These vehicles need to be topped off under normal conditions without leaks occasionally anyways.
