What is the appropriate antifreeze level?

It should be added between the maximum and minimum marks. Too much antifreeze can cause overflow, while too little can lead to poor engine cooling and potential engine damage. Additional information: Functions of antifreeze: 1. In cold weather, it prevents system failures and cracks in components due to cooling issues, while also managing rust prevention and preventing excessive scale buildup that could clog pipes. 2. It provides anti-corrosion, anti-scale, anti-boiling, anti-freezing, and anti-rust functions. Below are precautions when using antifreeze: 1. Try to use the same brand of antifreeze. 2. Most antifreeze products have a two-year validity period; ensure the product is within its validity period when adding. 3. Avoid mixing with water. Traditional inorganic antifreeze should not be mixed with water, as it can form precipitates that severely impair its normal functions. Organic antifreeze can be mixed with water but not excessively. 4. For vehicles using antifreeze, never directly add tap water; instead, use distilled or deionized water.

I've been driving for over ten years and always check the antifreeze before seasonal changes to ensure safety. Generally, using a refractometer or test pen to measure the concentration at around 50% is ideal, maintaining a freezing point between -35°C to -40°C. Too high a concentration, like 70%, may reduce cooling efficiency and cause engine overheating; too low, like 30%, can freeze in cold weather and damage the water pump. Regular testing not only prevents freezing accidents but also protects the radiator from corrosion and rust. Buying a simple tool to do it at home is convenient, and remember to replace it annually or every 20,000 kilometers. This way, driving becomes more reassuring and saves on costly repairs.

As a car enthusiast, paying attention to the test value of antifreeze is crucial. It's recommended to use a drop-in type tester, where a reading of 50% concentration corresponds to a freezing point of approximately -37°C, which is sufficient for most regions. Don't overlook this small detail, as significant deviations in the value may lead to engine overheating or freezing damage. Testing is also necessary in summer to prevent boiling issues. DIY testing is quite simple; after testing, observe the color change to ensure there's no contamination. Proper maintenance can extend your car's lifespan. Driving with fewer daily malfunctions brings peace of mind.

The ideal test value for antifreeze is a freezing point below -35°C, with a concentration maintained at 50% for optimal stability. When doing it yourself, purchasing a refractometer is both convenient and accurate. Too high or too low a concentration can affect cooling performance. Regular checks can save you from major repairs, typically requiring just an annual test. Ensuring the correct values means worry-free winter driving.

I often remind my friends to pay attention to the antifreeze test value, with the appropriate range between -34°C and -40°C freezing point. Using a pen-type tool to measure the concentration at 50%, if it's too low, it can easily freeze and damage engine components; if it's too high, it reduces cooling efficiency and causes overheating. It's recommended to check it every six months and adjust according to seasonal changes. Getting this small thing right can greatly improve driving safety and avoid unexpected breakdowns.
