overheating wierd?????

My brother has a 1992 3.8 thunderbird. He said that the car was shaking a little, so he said he was going to change the spark plugs and while he was doing that he would also flush the radiator and put some antifreeze. I told him I would help him but he didn't want to do it yet so I left for a couple of hours and when I got back he had already flushed the radiator and he was about to finish putting the spark plugs and new wires. when he was done we took it out for a spin but after about 2 miles the car heated up and it got to the L, I told him to pull over and I popped the hood and opened the radiator while it was still on but when I got off the car the exhaust was throwing out alot of white smoke, I was like WTF I checked the water reservoir and it was empty. I had just filled it up before we left. We let it cool down all the way for about an hour then we drove back to the house when we got home it was smoking again and it heated up to the L. I opened the radiator and filled it up with water I put 5 gallons and I filled up the reservoir. we turned the car off and let it cool, then 30 min. later we turned it on again and the exhaust threw out a lot of water and white smoke. I don't know what is wrong with it. I think he might have overheated it and messed up the head gaskets, I don't know :mad: :banghead: :banghead: :banghead:
, can someone help me.
thanks

I'm only a novice when it comes to cars and the mechanics of the various systems a car has. there are experts in this forum who can and im sure will help you a lot better than i. but from what i do know, it does sound like a head gasket problem. but i believe there are other problems as well that caused the thunderbird to over-heat so rapidly. good luck.

thedeal hit it out the park, your bro is the proud owner of at least blown head gaskets if not cracked heads. the white sugary smelling smoke is the #1 telltale sign of burning antifreeze. --enjoy--
