Check the stat first. If it's not opening you won't get any flow through the radiator/block/tank.

Usually the water pump impellor breaks up over time due to the antifreeze and the fact they tend to be plastic. The belt still drives the pump but it can't move any coolant, that then causes bits of the impellor to get into the cylinder head. If the impellor is u/s make sure you account for all the bits before fitting the new pump as it can quite easily block the head and overheat. If the pump seizes then yes it can snap the belt, unusual though.
Good practice and common sense says change the pump when you change the belt.
