Mechanical Problems!!!

Hello Everyone,
I am new to this site and in some desperate need of some help. I have a '95 Saturn SC2 that has been leaking antifreeze for a couple of months. The car begins to run too hot (to the red on the temp. cage) if I attempt to drive more than 10 - 15 minutes. In addition I have now begun to smell a new and curious oder from my car after i am done driving it.

I have been trying to find the answer to this for a while and in my attemps I have been told that it is: the temperature gauge, the cooling fan, the radiator, a sensor, a leak in the line somewhere between the antifreeze tank and the radiatior, a blown headgasket, and some other stuff that I can't remember at this moment. Anyhow, I am desperate, I love my car and I just want to know what is wrong with it so that I can fix it and drive it again.

Oh yeah, I have over 200,000 miles on it, could that be apart of the reason?

Thanks

any of those are possible, some more then others, can you tell us where it appears to be leaking from?(even just a general area)
