How to Replace the Coolant in a Volkswagen Sagitar?
1 Answers
To replace the coolant in a Sagitar, first use pliers to loosen the radiator drain at the lower left corner of the engine, allowing the old coolant to drain out. Then use an air gun to blow out any remaining coolant, add distilled water for rinsing, and tighten the clamp. Add new coolant, ensuring the level is between the max and min marks. Start the engine to bleed the system, and promptly top up the coolant if the level drops. Close the filler cap after topping up. Below are some coolant replacement precautions: 1. Coolant is not necessarily better when purer. First, avoid directly adding coolant concentrate, as this can lead to coolant deterioration, increased low-temperature viscosity, and higher engine temperatures, affecting the vehicle's lifespan. Second, always clean the engine cooling system before adding new coolant. Coolant can remove scale; if added directly, loosened scale may clog water pipes, leading to poor heat dissipation. Lastly, do not dilute coolant with tap water, as the scale and impurities in tap water can react with additives in the coolant, forming sediment. 2. Generally, the coolant in a Volkswagen Sagitar should be replaced every two years or 40,000 kilometers. This is just a reference interval; adjustments can be made based on actual usage. Extending the interval by an additional 10,000-20,000 kilometers or a year or so is usually not a problem. However, if the vehicle is used intensively, consider replacing the coolant earlier.
