Coolant Fan Sender

My radiator fan (single fan) does not turn on until the temp is over 240. Maybe I was sold the wrong sender. Anyone know what specific one I should buy?

Unless you buy a lower temp sending unit. They do sell them to kick off at 160deg. I just programmed my ecu to turn on the temps at 180
