How often should Volkswagen coolant be replaced?
1 Answers
Volkswagen coolant should be replaced every two years or 40,000 kilometers. Methods to determine when to replace coolant: 1. Check the coolant's instructions for use. Generally, coolant added to the radiator has a service life of two years. Not replacing the coolant for a long time will reduce the anti-rust quality inside the radiator, leading to damage to the radiator, pipes, etc. It will also affect the boiling and freezing point parameters, impairing cooling efficiency and causing harm to the engine. 2. Open the radiator and inspect the turbidity of the liquid inside. If it appears very cloudy and contains floating particles from corroded metal parts of the radiator, replacement is recommended.
