Do not choose antifreeze only by color! The possibility of error is very high! It is correct to use the product that was used when the car was manufactured. The antifreeze class is written in the user manual and is included in the selected programs. That is why you should ignore the color of the antifreeze. For example, the exact product https://cararac.com/coolant/ may be colored blue, green, red, or yellow. If you need a little refilling and the suitable antifreeze is not available, distilled water is added. This will compensate for the loss of fluid volume through evaporation. It is recommended to choose the antifreeze only according to the requirements of the car manufacturer!
