Are There Different Specifications and Models for Antifreeze?
2 Answers
Antifreeze does not have different specifications or models. Below are the detailed descriptions of antifreeze: 1. Freezing Point: Ordinary antifreeze can reach -40°C, while high-quality antifreeze can reach around -60°C. This is an important indicator to measure the quality of antifreeze. 2. Boiling Point: The boiling point of antifreeze should be above 108°C, and high-quality antifreeze can exceed 110°C. The lower the freezing point, the higher the boiling point. Here is additional information about the functions of antifreeze: 1. Heat Dissipation: Antifreeze, also known as antifreeze coolant, can cool and dissipate heat for the engine, transmission, turbocharger, etc. 2. Freeze Protection: It prevents the coolant from freezing in winter, which could otherwise expand and crack the radiator or damage the engine block or cylinder head. 3. Corrosion Prevention: Antifreeze has functions such as corrosion prevention, rust removal, and scale prevention.
There are definitely different specifications and models, as I've seen many examples when repairing cars. For instance, the colors are clearly distinguished: green is usually the most common IAT type, with basic anti-freeze and anti-corrosion properties; red or orange often indicates long-life OAT or HOAT types that can last five to six years without replacement, but they are only suitable for specific car models. Adding them to older cars can corrode radiator connections. The freezing points also vary significantly: some can handle southern winters at -30°C, while northern regions require below -40°C for safety. The most critical factor is still the car manual. Brands like Toyota and BMW have strict requirements for coolant—adding even a tiny bit of the wrong type can cause engine overheating or leaks, and repairs can cost much more than a few hundred bucks. So don’t skip checking the manual. Coolant might seem ordinary, but choosing the right model protects the entire cooling system and prevents a good car from turning into scrap metal.
