These switches are designed to monitor the temperature of your engine coolant and automatically switch the fan on and off as needed. This feature reduces power consumption and noise levels, which can make for a more efficient and comfortable driving experience.

Our fixed temperature switch sensor automatically turns on your cooling fan when coolant temp reaches 180º F making it an ideal option for all types of vehicles.

If you’re looking for more control, then our adjustable temperature switch sensor allows you to dial the degree you want your fan to turn on. Perfect for engines with an optimal operating temperature greater than 180º F. The adjustable dial allows you to set the fan to turn on anywhere between 180º - 240º F.

Fixed Switches: at 180 Degrees Fahrenheit (82.2 Celsius)

Adjustable Switches: between 180 - 240 Degrees Fahrenheit (82.2 - 115.5 Celsius) based on what you set

Zirgo® Temperature Switches are extremely accurate!

Fixed Switches: 4 degree accuracy

To ensure a consistent operating temperature for your vehicle's engine, be sure to install a Zirgo® Temperature Control Switch-Sensor with the correct relay for your fan.
