What Causes Antifreeze Leakage Under the Car?
1 Answers
Reasons for coolant leakage under the car: Radiator damage, poor sealing of the upper and lower water chambers. Loose connections and poor sealing at the overflow tank, water pump mating surface, and cooling system pipeline joints. Cylinder head gasket damage, excessive deviation or warping of the cylinder head and block mating surfaces, and loose cylinder head bolts, which allow high-temperature, high-pressure gases from the cylinders to enter the cooling system, leading to rapid coolant consumption. Antifreeze replacement cycle: Vehicle antifreeze generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference interval. For commercial vehicles with higher mileage, the replacement cycle should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Check the antifreeze condition regularly; if the level is low, top it up promptly. If suspended particles, sediment, or signs of deterioration or discoloration are observed, replace the antifreeze and flush the system immediately. Functions of antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round.
