White smoke out of tailpipe on 2002 Saturn SL2

Ok i got an answer on it this am and it wasn't doing it this morning or all day....now that I wentto the store I noticed the tempature rose to almost half way and it started to smoke real good and i pulled up in driveway and got out to smell it and it smelt sweet. So I gather it's coolant. How did this happen? and how do I fix the problem? Is it real serious?

You most likely have a blown headgasket. You have a coolant leak somewhere. It is serious and it is expensive to repair. Again like I said yesterday it could also be a cracked intake manifold.
