Thermo Fans & Switches

Thermo fansDavies Craig have the single largest range of Thermo fans available in the market today and have dedicated many years of product development and testing to ensure durability and quality. Davies Craig commenced manufacturing Electric Thermatic Fans in 1971. At that time, belt driven fans were the only option for automotive cooling.

Since the early 1990s, Thermatic Fans have been introduced as original equipment and most cars are now fitted with an electric cooling fan. Davies Craig Thermatic Fans & Fan Clutches are made to OE specifications.

The Fuelmiser Thermo fan switch complete range has over 70 part numbers for over 2000 applications.
Quality switches prevent overheating and potential damage to the engine ensuring smooth operation of the electric radiator cooling fan. The fan switch is a mechanical switching device, designed to respond to changes in coolant temperature allowing the operation of the electric radiator cooling fan.

The fan switch is an integral component in a vehicle cooling system. A faulty fan switch can cause possible overheating and potential damage to an engine. Fan switches should be inspected at regular service intervals. The switch should be inspected for any visible signs of contaminant and conductivity. Note that the coolant itself, particularly old coolant, incorrect coolant levels or mixture may cause the fan switch to malfunction.

  • Fan Switch temperature ranges and switching types may vary.
  • Some vehicles have more than one fan switch and more than one thermo fan.
  • Please refer to vehicle applications and images for correct fan switch applications.
