The engine has a thermostat, but that doesn't limit the heat the engine can make...it only establishes the minimum temp the engine can be once it warms up. The purpose of the thermostat is to cause the engine to quickly warm up to that minimum temp so that the engine doesn't stay cold for very long and so that you can get heat quickly in winter weather.
If your fans are not operating, the sensor switch for the fans may have failed; or a relay that is used to pass power to the fans (if your system has one) could have failed; or the fuse/circuit breaker for the fans/relay could be blown/tripped. If the thermostat were the problem, the engine would overheat but the fans would still work.

Pull the plug on the pass.side head and use a jumper wire to connect the terminals together. That should turn your fan on but I will tell you that engine has to get pretty hot(like 220degrees) before the sensor kicks that fan on
I only had mine kick on once on a 98 degree day in traffic with the a/c on full blast.
I have since gone too dual electric Flex-O-Lite fans. I run a steady 190

If you ground the green at the switch the fans shouldl kick on at all times.
It's been a long time, but i think the switch is set to kick on at 210 degrees.

I wondered about my fan also, as it never seems to kick on.....
The shop manual states that the aux fan kicks on at a whopping 238 deg F, then off again at 201. So, you have to get it pretty warm for that fan to kick on.

That electric fan doesn't move a lot of air anyways, it isn't the same motor as a newer cars electric fan motor. I would check your thermal clutch before even bothering with that electric fan. My electric fan has never work and mine has never run hot.
See if the mechanical fan freewheels and that will tell you if the fan clutch is shot.
