So I think my fans run too much. They don’t kick on when I first start my truck, but after the truck warms up a bit it seems like they never stop. I don’t think it used to be like that. They do shut off when the truck is off. Should it be like this and if not what could be some possible causes? Also, this is with the AC and defroster off. Thanks fam!

The fan kicks on when coolant temperature gets too high, generally between 200 and 230 F. Thinking logically, there could be something wrong with your coolant temperature sensor, if this is out of range, the fan kicks on at the wrong time. Do both fans kick on (it should be the case when A/C is off and engine reaches temperature)

Yes, both fans are running with AC off
