Why is my car smoking under the hood?

My i just changed the radiator, thermometer, and my car started smoking under the hood. The temperature didn't read hot or anything so i'm wondering what could be wrong. Its a 2000 Honda accorded if that matter.

The residual coolant that is on the hot parts of the engine are burning off you can only hope.

Is it white smoke? If it is white, then it is probably leaking on the exhaust or something hot causing the smoke. Check all the hose clamps to make sure you put the clamps on and make sure the hoses aren t damaged. I would then start the car and see where the smoke is coming from. Also check your thermostat housing to make sure there are no leaks there.
