Honda 2013 civic overheating
The hose to the coolant res was disconnected. Reconnected it and filled sys. Still overheated, took the radiator cap off and the spring and seat was missing. Radiator neck was malformed so replaced the radiator too. Blead sys and still overheating. Replaced thermostat. Filled system and blead system for 35-40 min with cap off radiator and adding coolant as needed. No apparent leak from the water pump. While bleading system turned on the ac and both fans ran and then stopped when turned off 3 times. Had the heater running full on and getting heat. All seamed fine test drive had overheat light come on after 30 min at highway speed. Oil was changed at the same time as thermostat. No steam or moisture at tail pipe.

Hope this helps, do this VERY Careful, when over heating Turn ON the heater to full, does it cool down? does the water in the Radiator Boiling?. = water pump, (don't always make noise).
Not boiling?- Check and R&R Heat sending Unit Gage on the Radiator or somewhere on the engine maybe close to the Thermostat..
All cars (I believe have a temperature gauge sensor to send the water temperature to the bulb to lite up the light or temperature gauge to move up or down). maybe you need to reset the computer signals notifications. do you see the water flowing inside the radiator?, no?, maybe something blocking water flow.. good luck.
