My cooling fan quit. I have checked the fan and fuse and they are good. I cannot find the sensor switch on the radiator on this model. Gasoline model 4010.
On my 1996 2510 it's on the right, rear side of the radiator. I had to remove a front wheel and inner fender to get to it. Mine failed after about 20 years. I jumpered the wired to it to verify the fan worked and the switch was bad.
