What is the reason for the low coolant warning disappearing after restarting?

[FinnFitz]

If the coolant warning light disappears after restarting, it is recommended not to continue driving. You can add coolant before resuming vehicle use. Function of automotive antifreeze: Another name for automotive antifreeze is coolant, which helps lower the engine temperature. Since the engine generates a significant amount of heat during operation, 60% of this heat is dissipated into the surrounding space through the cooling system. Water and methanol-based coolants have a low boiling point and are prone to boiling. If the vehicle operates under conditions where the coolant boils, even for a short period, it can cause engine damage or even complete failure. Precautions when replacing antifreeze: It is essential to use the same type of antifreeze as originally specified. Different types of antifreeze have varying chemical compositions, and mixing them can lead to sedimentation and crystallization. Additionally, the cooling effectiveness of the antifreeze may be reduced. Therefore, only the same type of antifreeze as originally used should be employed.
