Your vehicle’s engine operates at high temperatures, a necessity given that it relies on a series of small explosions to generate the power needed to get you where you want to go. To maintain optimal engine temperature, engineers have developed sophisticated cooling systems that utilize liquid coolant, hoses, and a radiator to transfer heat from the engine to the outside air.

For the system to function correctly, it must contain the appropriate amount of liquid coolant. To keep you informed about coolant levels, a sensor monitors this essential fluid. If the coolant drops below the required level, the sensor activates a warning on your dashboard. This alert may read “Check Coolant” or feature an icon resembling an old-style bulb thermometer immersed in liquid. Your owner’s manual typically provides clear information on what this indicator looks like for your specific vehicle.

If this sensor system malfunctions, you risk driving for an extended period with insufficient coolant in the engine, leading to excessive heat that may cause significant — and costly — damage.

There are several signs that may indicate an issue with your coolant level sensor. One common indication is if you refill the coolant tank, but the low coolant light remains illuminated. If you have any concerns about your sensor, please bring your vehicle in for a comprehensive inspection of the cooling system.
