What are the precautions for using automotive antifreeze?
1 Answers
Precautions for using antifreeze: 1. Do not mix different types of antifreeze: Different types of antifreeze have different freezing points due to their varying compositions. Therefore, antifreeze should be selected based on the temperature conditions of the vehicle's operating environment. Generally, the freezing point of the antifreeze should be 10~15°C lower than the local minimum temperature to prevent the antifreeze from losing its antifreeze function. 2. Do not dilute with water: Avoid diluting antifreeze with tap water. Antifreeze mixed with tap water will not only have an increased freezing point but will also gradually produce sediment due to the impurities in tap water, ultimately affecting the cooling system's performance. 3. Do not directly add concentrated antifreeze: The concentration of ethylene glycol in antifreeze is not necessarily better when higher. Directly adding high-purity concentrated antifreeze not only fails to meet the engine cooling system's requirements for antifreeze but may also lead to unexpected issues such as antifreeze deterioration, increased low-temperature viscosity, and engine overheating. Therefore, when using concentrated antifreeze, it must be mixed according to the specified requirements, and direct use is prohibited. 4. Regularly check the antifreeze level: The antifreeze level in the engine compartment's reservoir should be checked every quarter. The normal level should be between the MAX and MIN marks. If it is below the MIN mark, the same brand and model of antifreeze should be replenished promptly.
