Really there is no "what is normal" with the coolant temperature or fuel gauges. They are set at the factory as are the sending units (either bay design or adjustment). Over time the electronics wears and changes as do the gauges themselves. It is often the case that when changing one or the other parts the reading will differ. You can check you connections, grounds and power sources or even bend the needle a little to put it where you like, but not much else. You can try a different sender or gauge also but as long as it is not reading too close to cold or hot you might have to live with it. Just be sure the coolant is filled and no air is trapped inside or that it really is getting too hot.
