By still leaking, but not seeing it leaking anywhere, you are losing coolant with no external leaks. If you have this in conjunction with overheating, I would recommend the cooling system be tested for the presence of combustion gases. This would indicate an internal leak, head bolt thread failure most probable. 97 was a common year for this type of fault.
