Thermo Fan Switches

  • The thermo fan switch is designed to control operation of the electric thermo fan(s). The thermo fan switch responds to changes in engine coolant temperature, providing circuit switching during a predetermined temperature range allowing fan operation.
  • The thermo fan switch must be compatible with the vehicle engine management system; the Tridon thermo fan switch range has been carefully researched and engineered to operate within original equipment manufacturer's specifications for each specific application.
  • Please refer to the Tridon Part Finder for the correct thermo fan switch for your application.
