If there is 12v at the connector to the fan, the fan is bad.

Yes, there is a fan relay.

Yes, there is a thermosensor also..
If the engine warms to normal temp, and no voltage is at the
fan, unplug the wires from the sensor, and short together
with a jumper to bypass the sensor. If it now works, the
sensor is bad. If still no good, check the fan relay and wiring.

Overheating the typical aluminum or aluminum/iron motor is the
worst thing you can do. The kiss of death many times. I watch
my temp gauge often. Normally mine never varies from it's appx
1/3 level. If it even approached halfway, I'd know I was overheating,
and would shut it down. Usually the first engine related sign of
overheating is usually increased pinging.
If you ever start pinging real bad, shut it down and make sure it's
not real hot, even if the gauge reads ok. Actually, a gauge would
usually show it, but this is a good indicator on a car with an
idiot light. Many times a light won't go off until it's belching
steam..
