1989 Dodge Colt radiator ran dry, engine seems broken

Engine Mechanical problem
1989 Dodge Colt 4 cyl Two Wheel Drive 160, 00 miles

Tonight my Colt's radiator was pretty much empty when I put a gallon of antifreeze, and another gallon of water in it. I had not checked it for a long time, though I knew it had a leak. I very seldom drive it--sometimes only once a month, but the last two times I drove it, it was fine. No overheating. After I filled the radiator, I turned it on, and it started to sound VERY rough. I turned it off, then on again, and it made a bad loud sound and died. I tried it again and it turned over a couple times and made another bad sound and died. The radiator had leaked about a pint or so, which I mopped up, putting a pan under it. I am afraid it threw a rod or two, though no light was on and it had not run long enough to overheat or even warm up. Is this possible? I have to have someone look at it, but it cost only $550 three years ago, plus what it cost to fix a few things and get it smogged. Itis not a big financial loss, but I don't have another car which will travel on the highway. I have an all-electric G.E.M. Car, which also needs work. Light on this would be appreciated.
