Water Temperature Sensor & Water Level Alarm Series

This dual-function sensor series monitors both the temperature and level of the engine coolant. The water temperature sensor transmits data to the dashboard and ECU, triggering an alarm when overheating occurs; the water level sensor detects insufficient coolant and triggers a low liquid level alarm. It is the core safety component of the engine cooling system, compatible with passenger cars, commercial vehicles and multiple brands.
