⚡ At a Glance
- • Temperature Control: Adjustable range from 0 to 120°C via a capillary probe that senses coolant or contact temperature and triggers the fan at the selected setpoint.
- • Best for: Motorists and DIY mechanics who want simple, adjustable radiator fan control for routine cooling-system upkeep.
- • Not ideal for: Anyone needing integrated electronic diagnostics or plug-and-play digital systems with app connectivity.
Capillary thermostat with a stainless steel probe that measures water or coolant temperature. Probe-driven switch activates the cooling fan once the chosen temperature is reached.
Precise fan activation - thanks to capillary probe control
Probe measures the temperature of water, coolant or contact and transfers power to the fan when the selected temperature is reached. The capillary connection links the probe sensor to the controller allowing the fan to start at the setpoint.
Fan runs only when needed, helping to avoid unnecessary operation and keeping engine temperatures closer to the desired range.
Wide adjustment range - with 0–120°C selectable control
Black adjustable button allows setting the run temperature between 0°C and 120°C, giving a broad range for different cooling requirements. Calibration is manual via the control knob.
Suitable for a variety of engines and climates, enabling users to fine-tune when the fan engages for better cooling management.
Straightforward hose fitting - with probe-in-hose installation
Installation requires removing the top radiator hose, fully inserting the probe, then re-fitting the hose and tightening over the capillary wire; silicone sealant can be used to assist sealing. The probe attaches directly to the controller.
Simple for garage DIYers and routine maintenance, with an installation method that integrates the probe directly into the coolant flow path.
