How to Replace Coolant in a Polo Car?
2 Answers
The procedure for replacing coolant in a Volkswagen Polo is as follows: 1. First, turn off the engine for more than 30 minutes to avoid burns from high temperatures during operation; 2. Unscrew the radiator drain valve to let the old coolant drain out; 3. After no more coolant flows out, add clean water to the coolant reservoir to clean the pipes and flush out any remaining coolant; 4. When the drained liquid becomes clear, it indicates that all the coolant has been completely drained; 5. Tighten the drain valve and add new coolant up to the standard mark. The manufacturer recommends replacing the coolant in a Volkswagen Polo every 2 years or every 40,000 kilometers. If long-life coolant is used, the replacement interval can be extended appropriately. If scale or other impurities are found in the cooling system, the coolant should be replaced promptly.
I've been driving a Polo for several years, and changing the coolant myself is quite simple. The first step is to ensure the engine is completely cool—letting it sit overnight is safest. Then, locate the drain plug at the bottom of the radiator in the engine bay, use a wrench to gently loosen it, and drain the old coolant into a large basin, being careful not to splash it on yourself. The Polo also has a secondary reservoir, which needs to be emptied of old coolant as well. After draining, tighten the plug securely and slowly pour new coolant into the radiator up to the MAX mark. Remember to choose the coolant model recommended by Volkswagen—mixing it with 50% distilled water provides the best anti-corrosion effect. Start the engine and let it run for a few minutes to allow the coolant to circulate and release air bubbles. After turning off the engine and letting it cool, check the fluid level again to ensure it's correct. The whole process takes less than half an hour—it saves money and gives peace of mind. Just remember to change the coolant annually to protect the car and prevent the engine from freezing and cracking.
