How Many Kilometers Should You Drive Before Changing Antifreeze?
1 Answers
Antifreeze is recommended to be replaced every 2 years or approximately every 40,000 kilometers driven. Below is relevant information: 1. Currently, most antifreeze on the market is ethylene glycol-based, which has a shelf life of about two years. Therefore, it is recommended to replace it every 2 years or approximately every 40,000 kilometers. This is a general reference cycle for most household vehicles, and the actual replacement interval should be determined based on specific usage conditions. 2. Antifreeze, also known as antifreeze coolant, not only prevents freezing but also serves as a cooling agent. It contains various additives that provide additional functions such as corrosion and scale prevention. 3. For commercial vehicles like taxis or ride-hailing cars, which typically accumulate higher mileage, antifreeze consumption is greater, necessitating shorter replacement intervals compared to regular household cars. When antifreeze levels are low, it should be replenished promptly. Some car owners, aiming to save money, often use water as a substitute for antifreeze. This is highly inadvisable because water has a lower boiling point, which can lead to overheating during prolonged driving, and a higher freezing point, increasing the risk of freezing and rendering the car inoperable. Additionally, water contains impurities and various ions that can form scale and cause blockages.
