Elec rad fan: temp sensor on/off

Hi all. Can anyone recommend a good rad fan sensor (on/off). Mine just quit this morning after only about 1500 miles (18 months) usage.

1/2" NPT approx. 95 deg C (195 deg F) on/off.

Cheers
Greg

FWIW, the ERA cars use the thermo-switch from a 1980-1984 VW Rabbit or Jetta: 823 959 481. They operate at 75 centigrade in the bottom radiator hose. I don't think ERA has changed them in a long, long time and they rarely require replacement.

Unfortunately the VW switches thread is M22 or M24, not a US pipe thread.

Thanks guys. I may have been wrong and need a 3/8 NPT, but certainly not metric. And I need a male spade type wire connection. I'll keep looking for a good reliable replacement.
