How to Replace the Antifreeze in a Passat

[SanEloise]

The method for replacing the antifreeze in a Passat is as follows: 1. Remove the front grille, which can be done directly with a screwdriver; 2. After removing the screws, pry it open by hand to reveal the drain port, then unscrew the drain plug with a screwdriver; 3. Open the cap of the antifreeze filler port, wait until the colored antifreeze has mostly drained out, screw the drain plug back in, and refill with new antifreeze. The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and expanding in cold winter conditions, which could crack the radiator or damage the engine cylinder block or head. In daily use, the antifreeze should be replaced every 20,000 kilometers or once a year.
