What's going on?

Overheating
I was driving on the highway when the car over heated. So I dumped the antifreeze and put water in and the car ran fine. Later on I had the system flushed and put in 50/50. When I drive locally it doesn't overheat, but as soon as I get on the highway the temperature slowly rises. So I had two additional fans installed and it seem to cool it down, but every two days I was putting in antifreeze in. So I went to the dealer to get new thermostsat. The next day I put the car on the road and every thing seemed fine until I went about 25-30 miles and the temperature started rising again and the new fans couldn't control the temperature. By the way I have a 1999 deville d'elegance.

overheated
I have 156,800 miles on it. I use dexcool 50/50, but when I purchased the car last Feb. it had green antifreeze in it. Didn't notice it until I went to get oil change a week later. The antifreeze was filthy. So I don't know how long that antifezze was in there when I purchased the car. I had a bad leak in radiator, changed the radiator, hoses and thermostat. Car was running fine then gradually I was losing antifreeze, but lately I have to fill it up every other day. I just flushed and changed oil.
