By removing the wires on the coolant sensor. The computer sees high temp and fires off the fans. It does not mean it is bad.
If there is air in the system and the coolant sensor is not in fluid, it will not fire off the fans. You need to find out why the air is in the system. Thats why I said to have the system checked for a head gasket as it will air up the system.
