Yes, it does matter what coolant you put in your car. Different vehicles require specific types of coolant, as specified by the manufacturer, to ensure optimal performance and longevity of the engine. Using the wrong type of coolant can lead to corrosion, overheating, and damage to the engine components. Coolants have different chemical compositions and properties, such as varying levels of anti-corrosion agents and thermal stability, tailored to the materials used in the engine and cooling system. For instance, some coolants are designed for aluminum engines, while others might be suited for cast iron or mixed metal engines. Therefore, always refer to your car’s owner’s manual or consult with a professional mechanic to choose the appropriate coolant for your vehicle.
