It would do well to make sure it even has a thermostat in place (and working correctly).
It's entirely possible someone removed the thermostat altogether at some time if chasing an overheat problem.
I remember back in my younger years I sometimes heard somebody say "Just leave the thermostat out, **** it doesn't need one until winter."
