Yesterday i turned my car on because i returned from a vacation and just wanted to let it run for a bit. I noticed that steam or possibly smoke was slightly coming out of my grille and condensing on my hood. I opened my hood and noticed it seemed to be coming from the radiator, but coudn't find a particular starting place. Secondly i heard a persistant ticking noise but every other second an even loader tick would sound intermitantly. I was freaked out by all of this at once and am wondering if i am in for a big suprise. Thanx-any help is much appreciated!

 

How long was it sitting.
