I think you've got multiple problems here. First, your temp gauge is reading too high sometimes either due to a bad gauge or sender or the wire shorting to ground. Second, if your car is overheating, the connections at the fan relay have corroded.
That's my guess, but your car may also have air in the cooling system if it wasn't bled after the coolant drained.
Good water pumps will leak out the back long before they fail. After it leaks for a few months it will start to rattle.
