the cooling system is pressurized. any steam or hissing indicates a leak.
It might have had the wrong ratio or the wrong coolant in it at one time and is seriously clogged...take it to a shop or jiffy lube type place and have it pressure flushed to remove the sludge and oxidation...if that don't work, time for a new radiator. :(
Btw...you might want to be sure you fan is working too!! ;)
