Coolant Sensor

Monitor your engine's vital cooling system with this original Proton Geely Temperature Switch Sensor. This precision component is designed to accurately measure engine coolant temperature across the Proton X50, S70, X70 1.5L, and X90 1.5L models, sending critical data to your vehicle's ECU (Engine Control Unit).

The TAMA CS-401 Coolant Temperature Switch / Thermo Sensor (Fan Switch) is a genuine Japan-made component that ensures reliable cooling system control. With a 3-pin triangle socket design, it accurately detects engine coolant temperature and activates the radiator fan when needed, preventing overheating and maintaining optimal engine performance.
