Cooling fan not working??Will my machine blow??

[vickgeo1981]

Hi all,i have my Yaris since 2003-2004, and it was first run since 1999,since 2003-2004 except the alternator, nothing broke mechanically or electric(Except fuses and lamps)has broken,NOTHING,that's why i love this car,BUT since 3-4 days ago,i started seeing white smoke coming out of my right vent,only that, and it had a strange smell, i checked for the radiator cooling liquid and it was empty,so i put some cooling liquid i bought from a gas station and just drove off, next day i went to work and the exact same thing,i again filled it up, i checked the surroundings and there wasn't any drops of liquid on the floor, and it got my buzzled, then from time to time i stoped the car and checked the fan, it wasn't working(I do know that my car's fan doesn't work all the time,just when it's hot enough)but i did also turned the A/C and that should of kicked the fan to work,but that didn't).I am not a mechanic, i can't just say it's the fan, but i do think so, what do you people think. Thank you
