Is Red Antifreeze Universal?
2 Answers
Red antifreeze is universal. The correct steps for adding antifreeze are: Open the vehicle's engine compartment hood, locate the coolant reservoir in the upper right corner, open the antifreeze plug under the radiator, and directly add the antifreeze. The correct steps for replacing antifreeze are: Open the vehicle's engine compartment hood, locate the coolant reservoir in the upper right corner, open the antifreeze plug under the radiator to drain the old antifreeze, and then add new antifreeze. The functions of antifreeze are: 1. To provide anti-corrosion protection for the components of the cooling system; 2. To prevent scale formation and avoid reducing the radiator's cooling efficiency; 3. To ensure the engine operates within the normal temperature range.
The color of antifreeze is not universal, even if it's red. I remember once helping a friend fix his car—he mixed red antifreeze from one brand with another brand's red, and the car overheated and broke down. The color only indicates the type; for example, red is usually OAT (Organic Acid Technology) antifreeze, suitable for modern cars, but different brands have vastly different formulations. Mixing them can create gel-like substances that clog the cooling system, leading to engine damage. The repair cost over a thousand dollars. It's recommended to choose a product that matches your vehicle's manual and not cut corners for convenience. Check the antifreeze color once a year—if it turns cloudy or shows signs of aging, replace it immediately. Safety first.
