How to Determine if a Car Needs to Refill Antifreeze?

[DelAlejandro]

There are two ways to determine whether antifreeze needs to be refilled: 1. Check the dashboard coolant temperature warning light: When the coolant in the vehicle's cooling system is insufficient, the coolant temperature warning light on the dashboard will activate, prompting us to refill the antifreeze promptly. 2. Check the liquid level marks on the antifreeze reservoir: The antifreeze reservoir in the car's cooling system not only adjusts the volume changes of the antifreeze due to thermal expansion and contraction but also indicates the maximum and minimum amounts of antifreeze that can be added. There are two scale lines on the antifreeze reservoir. The lower scale line represents the minimum level of antifreeze in the cooling system. If the liquid level is below this line, it indicates a lack of antifreeze, and it needs to be refilled promptly. The upper scale line represents the maximum level of antifreeze that can be added to the cooling system. When the liquid level exceeds this line, some antifreeze should be drained.
