Is it normal to hear the radiator fluid boiling while driving in normal traffic? The temp gauge reads on the "O" in "NORMAL" but it freakin smells like fluid, i can hear it boiling, and the top radiator hose is solid as hell! does this make any sense to anyone? anybody know what could be wrong? im so pissed and on new years eve of all days. how can i be sure that its not the fan/t-stat/water pump? any help would be great fellas. thanx
