Core Functions

• Coolant Level Monitoring: Continuously detects the height of the coolant in the reservoir. When the coolant level drops below a preset threshold, it sends an electrical signal to the vehicle's onboard computer.
• Warning Signal Transmission: Enables the vehicle to display a warning light on the dashboard, notifying the driver of a low coolant level. This timely alert helps the driver take appropriate action, such as adding coolant, to prevent engine damage due to overheating.
• System Integration: Works in tandem with other engine management systems to ensure the overall stability and efficiency of the cooling system. For example, it can be part of a feedback loop that helps regulate the coolant flow based on the detected level.
