What is the best way to maintain the Audi A4's cooling system?

I've noticed that my Audi A4's engine has been overheating lately. What is the best way to maintain the cooling system to prevent this issue?

Make sure to regularly check the coolant levels and top off if necessary. Also, check for any leaks or cracks in the hoses and replace them if needed.

Another important factor is to flush and replace the coolant every 2-3 years. As coolant can break down over time and lose its effectiveness in keeping the engine cool.

If your engine still continues to overheat after these steps, it could be a sign of a bigger issue. It's best to take it to a mechanic for a check-up and proper diagnosis.
