Anyone encounter this problem before. Long story short....Last 2 days I topped my radiator with antifreeze. After 2 days I open it up and check it out, the antifreeze ran out already.....I was thinking bcuz the radiator fan is not function properly.....any suggestion would be great thx....

Have you investigated where it's going? It's essentially a closed system, so it's either leaking from somewhere, burning off, or expanding in to the tank.

 

i don't believe it leaking....but burning off i think might be the case...if that the case..what my next step should be...
