1997 Dodge Caravan Coolant light come on after hitting a de

I hit a deer, and stopped imed., And checked the front of my van, upon inspecting, I found that the front bumper was good, but the left drivers side headlight was caved in but still worked (high and dim beams) and that my hood, about half way up was 1 1/2 to 2 inches about where it should be. It was fine for about 15 miles and then I parked it for about 2 1/2 hours and then, when returning to drive it, I noticed that my check engine coolant light was on at about 3 miles after that. What do I do? Do I have a busted radiator or do I have other problems? Please help me, I do not have the money or the credit to fix this problem other than on my own at home. Thanks Again, Kelly
