    Go get the cooling system pressure tested.

    Possibly the cylinder head has a minor warp and the coolant is very slowly entering the combustion cycle in one cylinder. BUT, the most common slow or tiny leak is the radiator. It's hard to see it but you can smell it after the engine has warmed up and you've driven X miles. Just drive it and then pop the hood and follow your nose.

    Check the water pump for leaks.

    Look closely at the radiator and hose connections for crystalline deposits. Coolant with antifreeze dries to a bluish white powdery residue. You may never see drips as the heat from the components will quickly evaporate any small leaks.

    Could be going out the exhaust

    If you're losing coolant SLOWLY, it could be just a tiny pinhole leak in a radiator hose or somewhere in the cooling system. It doesn't have to be a huge big leak to lose a noticeable amount of coolant over time. Take your car to a REAL mechanic and ask to have your system pressure tested to check for leaks.

    It could be the water pump is leaking.

    Apart from the fact that it's 26 years old, you may have a crack in one of the pipes that's seeping out under pressure.
