When mixed with water in the proper proportions, the resulting solution greatly increases the cooling system's ability to perform its function of removing heat from critical engine parts while enhancing the service life of various cooling-system components. Straight antifreeze actually freezes and boils quicker than tap water. When in doubt, call the local dealer of the equipment you are servicing and ask them for advice.įor sure, always mix antifreeze with water (distilled water is much preferred) at a 50%-50% rate. “Today, however, coolants are crucial for heat transfer and corrosion protection as well.” “Way back when engines were simpler, the primary goal of radiator fluids was to prevent engines from freezing,” says Carmen Ulabarro, a coolant specialist with Chevron. ACDelco 10-101 DEX-COOL Extended Life Coolant - 1 Gallon. Genuine Toyota Parts - Genuine Toyota Fluid 00272-1LLAC-01 Long Life Coolant - 1 Gallon (002721LLAC01) 4.8 out of 5 stars 758. Only when dilution rates border 50% is the effectiveness of each coolant’s inhibitor package compromised. Genuine Subaru SOA868V9270 Super Coolant. If you do not know what coolant is in the vehicle and you top its radiator off with another brand, nothing bad is going to happen. They are not interchangeable and should not be mixed. The key is to buy the same type of coolant recommended by your machine’s manufacturer. From model year 04 to the present, they use pink super long life coolant that comes pre-mixed with water. Markets Analysis Back to Markets Analysis.However, if you’re unsure of which fluid to use to keep your vehicle performing at its best, refer to your owner’s manual or ask a trusted mechanic. We selected five of the best-rated antifreeze and coolant fluids that are also compatible with most vehicle makes and models. When browsing the various types of fluids, it’s easy to get confused. As a consumer, you should pay attention to the color of the coolant you choose because the wrong color may shorten. They do it for several important reasons. Coolant manufacturers don’t add color to their antifreeze just to make it look pretty though. Running your car on older deteriorating antifreeze or coolant can cause acid buildup, scaling and reduced resistance to extreme temperatures. All the green, orange, red, pink, amber, and blue coolants you see on the shelves are dyed. The longer you use coolant, the more its useful chemical properties break down. Performing routine maintenance on your vehicle’s cooling system will ultimately prolong the engine’s life. This technology provides superior protection to all components of the cooling system including those exotic materials like aluminum and magnesium found in the modern day engine. Antifreeze also fends off rust and corrosion, helping to extend the life of water pumps, radiators and other cooling system components. OATs are Long Life Coolants (LLC), based on minimally depleting Carboxylate Technology. In the winter, the chemical formulas in antifreeze also prevent water and moisture from freezing, which can damage the cooling passages inside the engine and other components just as it would the pipes in your house. Combustion engines generate lots of heat, and coolant, a mixture of antifreeze and water, plays a vital role in regulating their operating temperatures.
