Cap is on the passenger side, hose from the thermostat housing goes to a driver side of the rad

So once the water burped out of there -- and made a mess -- it should STOP doing that after it's initial puke....
Then -- YES -- you should top off the radiator - using only distilled water or a mix of distilled water and the proper anti freeze (for aluminum radiators!)... when the engine is NOT running... these big crossflow radiators should only be filled til there is about 6" of free space in the tank. Sometimes you'll need a flashlight to look in.... leave some space! Water expands - and these big radiators need some room for expansion.... If you fill them to within a couple inches of the cap -- they'll puke out!
You might find that if you haven't topped off the radiator since you puked some coolant - that is your trouble right there....
