How Often Should Antifreeze Be Added?
1 Answers
For ordinary cars, antifreeze should be replaced and refilled every 2 years or 40,000 kilometers. For commercial vehicles, the frequency of antifreeze refilling is more frequent. Below is a detailed introduction about antifreeze addition: 1. During car maintenance, pay attention to the antifreeze level. Once the antifreeze level is below the minimum water level mark, it needs to be replenished in time. Note that antifreeze has a shelf life, usually about 2 years, while high-quality antifreeze can last up to 5 years. Once antifreeze exceeds its shelf life, using expired antifreeze can easily cause rust in the engine water passages, leading to blockages and resulting in engine overheating or even 'boiling over.' 2. When adding antifreeze, pay attention to the following: First, identify the antifreeze filler port, which is marked with a thermometer-like triangular symbol on the antifreeze reservoir cap. Second, do not mix antifreeze of different brands or colors, as their different compositions and formulas can cause chemical reactions that affect the antifreeze's performance. Third, choose a high-quality product of the same brand and model as the original antifreeze. Fourth, antifreeze is somewhat corrosive, so avoid contact with skin and other rubber parts. If spilled, rinse immediately with clean water. Fifth, always add antifreeze after the vehicle is turned off and cooled down to prevent the antifreeze from being ejected due to internal pressure when opening the cap in a high-temperature state, which poses a risk of scalding.
