Does Overfilling Coolant Affect Volkswagen Cars?

[MacHenry]

Overfilling coolant in Volkswagen cars does not have a significant impact, as the cooling system of Volkswagen vehicles is equipped with a pressure regulation device. After the car starts, the excess coolant can overflow through the pressure relief valve due to the principle of thermal expansion and contraction. Location for filling coolant in Volkswagen cars: The function of coolant is to prevent freezing and provide cooling. When filling, since the coolant reservoir in Volkswagen cars has a max (maximum) and min (minimum) water level mark, you only need to fill the coolant to a level between the max and min marks on the reservoir. Precautions for using coolant: Coolant should not be mixed, and low-quality coolant should not be used. Also, avoid directly adding concentrated coolant to prevent issues such as coolant deterioration or thickening at low temperatures. Regular inspection and replacement of coolant are also necessary.
