Do Cars Need Antifreeze in Winter?

[MacVanessa]

Cars need antifreeze in winter, and the precautions for replacing antifreeze are: 1. Choose antifreeze with a low freezing point and high boiling point, and good anti-corrosion performance; 2. When replacing antifreeze in the vehicle, drain the existing antifreeze and clean it thoroughly; 3. Check the coolant hoses for any signs of aging and replace them promptly; 4. Do not add too much or too little antifreeze, refer to the scale line; 5. After adding antifreeze, wait for the fan to start running, indicating that the antifreeze is working. The functions of antifreeze are: 1. To provide freeze protection for the engine against low-temperature environments; 2. To prevent the coolant from freezing and cracking the radiator or damaging the engine block and cylinder head when parked in cold winter; 3. To provide efficient heat dissipation.
