250 is way to hot. The fans should turn on long before that.

hi...180-205 i think...jump power and ground to the fan its self and see if it runs. then you will know if the fan is bad or if you need to be looking somwhere else. the sending unit are around $15.00

I know the fan is good, I've hooked jumper leads up to it and it worked, is there a thermometer that is supposed to tell the relay to turn on?

Check the sending unit that tells the electric fan when to engage. It's probably gone bad. Very common problem.
