How often should the coolant be changed in a Volkswagen?
1 Answers
Under normal vehicle usage conditions, it is recommended to change the coolant in a Volkswagen every 2-3 years. Below are specific details about the functions of automotive coolant: Anti-freeze function: Coolant has an anti-freeze function, preventing the freezing of the liquid in cold winter conditions, which could otherwise cause the radiator and engine block to crack due to expansion. Other functions: Coolant also has anti-boil, anti-corrosion properties, provides some lubrication, and prevents scale formation. The coolant is typically pink in color, with a freezing point above -35 degrees Celsius, protecting the cooling system and metal components from corrosion and scale buildup, while also increasing the boiling point of the cooling system.
