Thermostat: It regulates the engine's temperature and it changes the refrigerant flow into the radiator.

It is activated automatically due to the temperature of the refrigerant that flows into it. If the temperature is low, it will be closed and it will stop the refrigerant from flowing into the radiator, and this will keep the engine warm (during the ignition process or in really cold days). If it is hot, it will open and let the refrigerant flow through the radiator.
My 2000 1500 Silverado started running when I was hauling something a few weeks ago and would cool down when I would turn it off. Then it started getting no matter what if I was hauling something or not so I changed the water pump, fan clutch, radiator, all new holes, new thermostat
My van's fans are suddenly turned on and the temperature's pressure gauge is disabled. On top of that, a script warns that there is an engine overheating. The thermostat and temperature sensor were replaced, it worked better for two months but the problem is now back. What might it be?
Do you know whether your new temperature sensor is a good quality one? Nowadays there are many of them out there that are cheaper but only last for some weeks, or in the best of the cases months. You should check this first of all.
