The global Coolant Level Sensor market size is predicted to grow from US$ 1306 million in 2025 to US$ 1779 million in 2031; it is expected to grow at a CAGR of 5.3% from 2025 to 2031.

A coolant level sensor is a device used in vehicles to monitor the level of coolant in the radiator or coolant reservoir. It is typically a float-type sensor that is mounted in the coolant tank and connected to the vehicles electrical system.

The sensor works by detecting the position of the float, which rises and falls with the coolant level. When the coolant level is low, the float drops, causing the sensor to send a signal to the vehicles engine control unit (ECU) or dashboard warning light. This alert notifies the driver that the coolant level is low and needs to be topped up.

The coolant level sensor is important because it helps prevent engine overheating and damage. If the coolant level drops too low, the engine may not be properly cooled, leading to overheating and potential engine failure. By monitoring the coolant level, the sensor helps ensure that the engine remains at a safe operating temperature.

In addition to monitoring the coolant level, some coolant level sensors also have the ability to detect coolant leaks. If the sensor detects a sudden drop in coolant level that cannot be explained by normal evaporation or consumption, it may indicate a leak in the cooling system. This can help prevent further damage and allow for timely repairs.
