Where is the coolant drain port located on a Volkswagen?

[AllisonMarie]

The coolant drain port on a Volkswagen is located at the bottom right corner of the radiator. Introduction to Coolant: The full name of coolant should be antifreeze coolant, meaning it has antifreeze properties. Coolant prevents the liquid from freezing during cold winter parking, which could otherwise cause the radiator to crack or damage the engine cylinder block or cylinder head. Functions of Coolant: It provides anti-corrosion protection for components of the cooling system; prevents scale buildup, avoiding reduced heat dissipation in the radiator; and ensures the engine operates within the normal temperature range. Replacement Interval: Coolant is typically replaced every two years or 40,000 kilometers.
