How often should the antifreeze in a new car be replaced?
1 Answers
New car antifreeze should be replaced every two years. Antifreeze, also known as antifreeze coolant, is a type of coolant containing special additives, mainly used in liquid-cooled engine cooling systems. It contains calcium chloride, methanol, ethanol, ethylene glycol, and glycerol. The method for replacing antifreeze is as follows: 1. Open the car hood after the engine has cooled down; 2. Open the antifreeze reservoir cap; 3. Lift the vehicle and open the radiator drain plug, drain the old antifreeze, and then reinstall the drain plug; 4. Lower the vehicle and pour new antifreeze into the antifreeze reservoir. Precautions for replacing antifreeze include: 1. Choose antifreeze with a low freezing point, high boiling point, and good anti-corrosion properties; 2. When replacing the antifreeze in the vehicle, ensure the old antifreeze is completely drained and the system is cleaned; 3. Check the hoses for any signs of aging and replace them promptly if necessary.
