Cooling thermostat for 12V fan control that switches a fan on at a chosen temperature and off again as coolant cools. The Baceyong Universal Capillary Thermostat helps DIYers and car owners avoid overheating and noisy fans by keeping control straightforward. Is this the right fit for your vehicle or aftermarket fan setup?
⚡ At a Glance
- • Temperature Range: Adjustable 0°C–120°C, suitable for a wide variety of cooling thresholds
- • Best for: DIY mechanics and car owners fitting aftermarket 12V cooling fans
- • Not ideal for: Systems without a place to hose-mount a capillary probe or non-12V fans
Capillary thermostat with a stainless temperature probe that measures water, coolant or contact temperature and passes power to a 12V fan. Wide adjustable range lets users set the activation point between 0°C and 120°C for flexible cooling control.
Prevent Overheating - with a stainless temperature probe and automatic switching
Probe measures water, coolant or contact temperature and passes power to the fan when the selected temperature is reached, then switches off as the temperature falls. The capillary sensing element reacts to fluid temperature changes to trigger the fan circuit.
Automatic fan activation keeps coolant temperatures under control while avoiding constant fan running, helping reduce unnecessary wear and noise.
Customisable Activation - with a wide 0–120°C adjustment range
User-settable thermostat allows selection of an activation threshold anywhere within the 0°C to 120°C span, enabling precise control of when the 12V output engages the fan. Adjustment mechanism provides incremental control over the trigger point.
Fine-tune cooling behaviour to match engine size, vehicle use, or local climate without changing hardware.
Straightforward Retrofit Installation - with a hose-mounted capillary probe
Probe fits inside a radiator hose by removing the top radiator, fully inserting the probe, then re-fitting the hose and tightening over the capillary wire; silicone sealant may be used for an improved seal. Design suits common aftermarket fan installations with a 12V supply.
Simple fitting makes upgrades practical for home mechanics and reduces the need for complex modifications.
