Why is there still smoke coming out of my hood?

I just changed the pipe that goes to my radiator. It had a leak and the coolant was burning off so I thought. Now I that the pipe is changed there is no leak. But there is still smoke coming out. How do I know if it's still the coolant or if it's something else?Why is there still smoke coming out of my hood?try and look to see where the smoke is coming from, if it's still your pipe make sure the clamps are tight, you could still have some wet spots on the engine from the waterWhy is there still smoke coming out of my hood?that,s steam ,not smoke. maybe there is still anti-freeze laying on the intake and burning. if it,s smoke then you might have a valve pan gasket leaking.
