What causes a thermostat to fail?
Once the coolant engine reaches proper operating temperature, typically 180 to 200 degrees, the thermostat opens up and allows the coolant to flow through the engine. Sometimes the thermostat fails and must be replaced; there are four main reasons for failure: overheating, sludge, defect and age.
Is 180 or 195 thermostat better?
the 180 will open earlier and will allow the engine to run cooler in general although I have heard of people going to the 180 or 160 and running hotter as a result of the thermostat just staying open and never allowing the coolant to cool. The 195 is better for winter as it will allow the engine to run slightly hotter.

Does the coolant temperature sensor control the fan?
The sensor works by measuring the temperature that’s being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system. As the control system receives the temperature from the CTS, it may trigger the cooling fan to either shut off or turn on.
