![]() 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. Other supplemental inhibitors are neither needed nor recommended.Someone posted this on ToyotaNation and thought it gave some insight to the coolant madness in today's cars, especially Toyota: Toyota Super Long Life Coolant is also designed to provide engine protection down to minue 35 degrees Celsius, thereby removing the need to add anti-freeze to the engine’s cooling system in even the coldest Australian winter. Low-emission technologies such as those used in Toyota’s family of VVTi engines result in higher internal engine temperatures.Īt the same time, efforts to reduce the size and weight of engines have resulted in a reduction in the volume of coolant in the engine, meaning the remaining coolant is required to perform more efficiently. Toyota’s adoption of HOAT engine coolant is a response to changes in modern engine technology. It also uses hybrid organic acid technology (HOAT) which combines the benefits of organic and non-organic materials to maximize corrosion inhibition. Toyota Genuine Super Long Life Coolant has been formulated without the use of potentially abrasive silicate, or the potentially carcinogenic combination of amine and nitrite found in some other coolants. Many modern engine coolants contain toxins and must be disposed of at a waste management facility. Toyota Australia states that the extended service life of the new coolant has the added benefit of reducing the impact on the environment caused by the disposal of used automotive coolant. “Given that the average Australian car travels less than 20,000 kilometres a year, most motorists using Toyota Super Long Life Coolant will never need to have it replaced during the time they own the car,” says the senior manager of Toyota’s Customer Services Division, Tony Bottacin.Įach individual vehicle may vary and motorists should regularly check their coolant. Subsequent Super Long Life Coolant changes need only occur once every 80,000 kilometres - or 75,000 kms for Camry and Avalon. This is four times the recommended 40,000 kilometre replacement interval for Toyota’s previous long life coolant. Toyota Genuine Super Long Life Coolant requires changing for the first time only after the vehicle has travelled 160,000 kilometres - or 150,000km for Avalon and Camry. Toyota Australia has launched a new engine coolant featuring a substantially increased service life. ![]()
