:mad:I have a 2006 ranger 500 4x2 that the fan won't stop running, I have to disconnect the battery. Everything was fine when I stored it for the winter and now the fan never stops running and it is not getting hot, and the check engine or temp light stays on as well. Please help

If the coolant temperature sender or circuit malfunctions, the fan will default to on all the time. I would check your wiring but the sensor is probably in need of replacement.

Fan still running

I have replaced the thermo sensor and flushed out the radiator and the fan continues to run. I have also tried disconnecting the sensor altogether and It still runs. Do you have any other ideas? Is my ecm bad maybe?:mad:
