Automotive cooling controller designed to manage fan activation and keep engine temperatures steadier. Drivers who worry about overheating or inconsistent fan behaviour gain simple, adjustable control with Riloer Capillary Car Thermostat. Is it the right upgrade for a vehicle's 12V fan circuit?
⚡ At a Glance
- • Temperature Control: Precise fan activation to help keep engine temperature stable
- • Best for: Drivers wanting straightforward control over cooling fan behaviour
- • Not ideal for: Vehicles lacking a 12V fan circuit or those needing OEM-integrated systems
Compact 12V capillary thermostat that activates cooling fans at chosen thresholds. Suited to managing engine cooling across everyday driving conditions.
Consistent engine temperature - with adjustable 0–120°C capillary probe
A stainless steel probe senses the temperature of water, coolant or contact points, then transfers power to the fan when the selected threshold is reached. The black adjustable knob sets the activation point within the 0 ℃ to 120 ℃ range.
Stable fan activation reduces the risk of overheating and helps maintain steady operating temperatures. Useful for hot-weather driving or when towing, where cooling demand rises.
Easy installation and control - with straightforward capillary switch design
Construction uses familiar steel and plastic components with a probe attached to the controller, designed for integration into a 12V fan circuit. The simple knob control lets the activation point be changed without specialist tools.
Quick to set up for competent DIY mechanics, and simple to adjust when seasonal conditions change. Effective for anyone wanting a hands-on way to tune fan behaviour.
Durable construction - with stainless steel probe and robust materials
Manufacture combines high-quality steel for the sensing probe and durable plastic for the controller housing to handle routine automotive use. Materials chosen for longevity under regular temperature cycling.
Long service life reduces the need for frequent replacements and keeps cooling reliable over time. Suitable for everyday driving where resilience matters.
