Yes they have a thermostat, but I would look closely at the radiator, the grill in the front just pops off and if you will take the side shields off you can clean it well, dont use the high pressure car wash cause it will bend the fins, just use a garden hose and soak it then wash awhile it may take awhile but make sure its clean on the bottom and sides by the fan,you haven't drained and refilled the radiator have you? are you sure it's full? You have to take the front rack off to get to the cap.

Working on a customers 04 700 with same symptoms (customer replaced thermostat,hot light sensor,and radiator cap!) I tried to purge all air from radiator,and rechecked his work,plus checked impeller vanes.His problem was internal radiator blockage, fan would come on before hot light,but radiator not freeflowing enough to keep from over heating. Not very common but can happen. Hope this is not your problem.

99% of the time the thermostat is fine and its more of a rad. blockage issue. if you cant see thru the rad fins than chances are if its more then 25% blocked then thats the issue. if its not enought to overflow the coolant bottle then its overheating for sure. imo.

My o4 700 was overheating over a month ago.I completely removed the radiator and just about the entire back side of it was covered with a layer of hardened mud
I cleaned it real well and changed fluid and it is fine now, the fan runs the least I believe than it ever has.
