Can antifreeze be added directly to the vehicle?

[Moore]

Antifreeze can be added directly, but it must be of the same type. Different types of antifreeze should never be mixed, as this can cause chemical reactions, sedimentation, or bubble formation, which may damage rubber seals and often lead to leaks at the water pump seal or weld joints. Antifreeze replacement cycle: Vehicle antifreeze generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference cycle. For commercial vehicles with longer 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 level and top it up promptly if it is low. If suspended particles, sediment, or signs of deterioration or discoloration are found in the antifreeze, replace it immediately and clean the system. Functions of antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It provides excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round.
