The sender should be very near the thermostat. The thermostat is on the front of the engine. just above and to the right of the fresh water pump, ie the engine water pump.

Once you find the sensor I would make sure the wire is connected and that the connection is clean.
I *think* that if you remove the wire from sensor and ground it (hold it against a shiny bolt on the engine) the gauge should read full hot.
