Car company A sells their own brand of coolant that is X color. Other Asian companies may use Blue, Green, or whatever. The Toyota Pink is not backwards compatible for the older years, like our Camrys. The Toyota Red is forward compatible to the newer years as well. Toyota uses Red (concentrated) or Pink (diluted). The colors are ONLY for ease in identification of the coolants because certain auto manufacturers used certain colors. I confirmed this with a Beck/Arnley specialist who told me that their four colors (Red, Pink, Blue, Green) were actually the exact same thing (two are concentrates and two are diluted with a slightly different additive).
Do you think your Toyota can sense what color dye is in your coolant? Huh? I personally don't mix the colors, but if you do it's OK as long as the ingredients are the same. As long as the ingredients are the same, that is what counts. There may be others, but as long as it's a phosphated OAT (HOAT) with no silicates, no borates and no amines, you are good to go. There are a couple of non-Toyota coolant brands that I know of that fit the bill: Beck/Arnley, Pentofrost A1 (Made by a German company named Pentosin), Zerex Asian Vehicle formula (but I can't find it in concentrated only pre-mix).
BUT, it does not have to be the Toyota red or pink coolant, as long as the ingredients are the same. This means that most coolants on the shelf at your local auto parts store will NOT fit the bill. The coolant should be made out of ethylene glycols, phosphates (inorganic acid salts) with Organic Acid Technology (which makes it a Hybrid Organic Acid Technology or "HOAT"), no silicates, and no borates or amines (2-EHA is an amine). I came to the conclusion that there is a specific type of coolant that the Asian engineers decided works best in our cars. I researched this almost an entire day a while back. Perhaps I can help with the coolant issue.
Toyota super long life coolant and dex cool interchangeable manual#
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.Someone posted this on ToyotaNation and thought it gave some insight to the coolant madness in today's cars, especially Toyota: 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. Running your car on older deteriorating antifreeze or coolant can cause acid buildup, scaling and reduced resistance to extreme temperatures. 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. Antifreeze also fends off rust and corrosion, helping to extend the life of water pumps, radiators and other cooling system components. 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.
