What is the appropriate level to fill the coolant to?

[RicardoAnn]

The coolant level should be filled between the maximum and minimum marks. Below is relevant information: 1. To allow the antifreeze to flow quickly into the radiator, after draining for about 1 hour, add new antifreeze through the radiator hose. Add another bottle of antifreeze to the coolant reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. As some air is expelled from the cooling system, the coolant level will drop slightly. Then, add more antifreeze to top it up. 2. High-quality antifreeze is made with distilled water and contains anti-scaling additives. It not only prevents scale buildup but also has descaling properties. Of course, if there is heavy scale buildup in the radiator, it is best to thoroughly clean it with a radiator cleaner before adding the antifreeze.
