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

TCS/thermostat

Chevrolet Silverado 2014 crew cab, 5.3, LT 160000 miles

Good day, I have had to replace CTS(coolant temperature sensor) (several times) and thermostat(once) in order to stop my radiator cooling fans going off full blast and not turning off after shutting engine off. I have enough coolant; truck does NOT have relay for fans, it has fuses, and they are good. Please advise at convenience and thank you.

Fans failure

Chevrolet Silverado 2010 64000 miles

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.

Running hot

Chevrolet Silverado 2000 1500 truck 5.3 160000 miles

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

Could be head gaskets.
