I've seen both the UBV (useless bypass valve) and Prestone quick-flush fitting, e-mail me a picture of it and I can ID it for you.
If three hoses tee into it, it's the UBV. If it's only inline for one hose it's probably the Prestone bit.
Two new heater hoses (7513435 and 7545544) will swap out for the three currently on the UBV. Those valves are useless because 99/900s were built for twenty years without them and they worked fine and because they dissolve internally leading to full bypass and no heat. Or they fall apart and spray all your coolant out as you may have experienced.
While you're at it, you may want to change your thermostat and thermoswitch if you haven't done so recently to keep things cool (and your head gasket intact). It's twenty bucks of cheap insurance.
