Antifreeze Coolant FunctionĪntifreeze coolant plays a very important role in the overall well-being of your car. Some are made for more general use, while others are made specifically for high-mileage vehicles. Antifreeze coolant is made up mostly of the base chemical ethylene glycol, and there are a whole host of different types of antifreezes out there. You cannot mix Star Brite with other antifreeze coolants, as it can be easily contaminated.Antifreeze, which is also commonly called coolant, is a green or orange liquid that is mixed together with water before being poured into the coolant reservoir located under your car’s hood. BMW engines tend to overheat faster than other car models and need a BMW coolant with a higher boiling point than the Star Brite antifreeze. Moreover, its performance is limited with most BMW car models. The downside of this product is that it is more expensive than non-synthetic antifreeze. Its sealing properties also make this antifreeze a great choice for preventing system failure. Moreover, the fact that it’s devoid of the aforementioned harsh compounds makes it safe for parts like seals, welds, and gaskets.
It does not contain any nitrate, borate, silicate, phosphate, or amine in its formulation. Star Brite is an OEM- and ASTM- approved the product and comes as a ready-to-use coolant. The manufacturer includes a PSV additive in its formulation to regulate the engine temperature and seal pinhole leaks. Star Brite lowers operating temperatures in the engine faster than most coolants. It is an eco-friendly product and is also safe for metal engines like iron, aluminum, and copper. Star Brite is a synthetic coolant tailored to resist the breakdown of components over time. This antifreeze is suitable for LP, CNG, gasoline, and light-duty diesel engines. The cooling point is also lower than other high-performance coolants. You would have to buy a water-free prep fluid to flush out the water-based coolant from the system.
This antifreeze is expensive, however, and you need to convert your vehicle to a water-free coolant system which could take a long time. In addition, it remains stable and maintains its liquid state at temperatures as low as -40 degrees Fahrenheit. In case temperatures exceed its boiling point, this coolant will vaporize at a low pressure to reduce coolant loss and minimize strain on the car’s cooling system. This engine coolant has a high boiling point of 375 degrees Fahrenheit, meaning it won’t vaporize or cause boil over problems at that temperature. It is the best antifreeze for vehicles with overheating problems as it doesn’t create hot spots or engine knocks. This antifreeze is a propylene glycol-based formula that is non-reactive and, therefore, doesn’t cause electrolysis or cavitation erosion issues. Eliminating water from its formulation makes the coolant more resistant to corrosion to give your engine a longer life. This will also save you some costly repairs.Įvans High-Performance Coolant tops our list as the best antifreeze coolant due to its high performance as a water-free coolant. It also extends the life of plastic and rubber components in the cooling system that often melts as the system overheats. Antifreeze liquids prevent electrolysis that leads to the erosion of metal components. Most antifreeze liquids, on the other hand, stay neutral despite temperature changes to prevent the freezing or overheating of critical engine parts. Water has low boiling and freezing points and is, therefore, not a suitable coolant in places with extreme weather conditions. Antifreeze coolants were created to overcome the shortcomings of water as a coolant. This domino effect results in an engine failure that could have otherwise been prevented. With time, the unlubricated metals could start hitting each other in the combustion process. When an engine overheats, the oil in the system starts to thin. While regular coolants flush away the rust and deposits, antifreeze coolants have additives that prevent rust and corrosion from occurring in the first place. Rust and scale deposits tend to build up over a vehicle’s cooling system over time. They prevent cooling systems from overheating during extreme heat conditions and from freezing during the winter. Antifreeze liquids are better at dissipating heat than other coolants.
