Nothing if you drain it out and flush the cooling system. Oil is not a good coolant, and the water pump will have a hard time pumping it, so the vehicle will overheat if you do not remove the oil.

What happens if you put antifreeze in where the oil go?

If you start and warm up your engine: 1) The oil gets very foamy and mucky, and does not circulate through the engine properly. 2) The water in the antifreeze can heat up until it turns to steam, which expands with great force, and breaks some part of the engine. It's best to have the oil changed. That will empty the engine of the oil and antifreeze mix.
