(red maximum -30, green -25, yellow -20 It is also not recommended to mix antifreezes, even if the colors match (and change completely !! especially if you do not know what liquid is poured into the radiator !!!), a common opinion about compatibility antifreezes by color - it is wrong, the coincidence of color does not guarantee the use of the same additives, and the result of the interaction of various additives may be a deterioration in anticorrosive and lubricating properties.Īny antifreeze is a mixture of ethylene glycol (polypropylene glycol), water, dye and additive package. And Toyota's recommendation will never touch on color, because some Asian manufacturers share the freezing point of antifreeze by color. This does not prevent other manufacturers from producing antifreeze with similar performance without being tied to color. The manufacturer Toyota itself does not recommend the use of "purely red antifreezes", its recommendation concerns only the use of the original fluid, or the composition of certain chemical standards. Manufacturers paint carboxylate antifreeze, usually red. In addition, carboxylate antifreeze has a longer service life (5 years versus 3 for silicate) and better detergent properties, which makes it possible to do without flushing the OS during antifreeze change. They do not form a thick protective layer over the entire surface of the system, but are adsorbed only in places where corrosion occurs with the formation of protective layers no more than 0.1 microns thick. Manufacturers paint silicate antifreeze, usually green or blue.Ĭarboxylate antifreeze contains organic acid based corrosion inhibitors. ![]() Silicate antifreeze, protecting the OS from corrosion, during operation, covers its entire inner surface with a thin layer of scale, which worsens heat transfer in the OS and reduces its efficiency. Рanoil Kuttenkeuler ANF 40 (color: yellow)Ĭool Stream Premium 40 (orange) And so for information:Ĭurrently, antifreezes are divided into silicate and carboxylate antifreezes by the type of anti-corrosion additives. Рanoil Kuttenkeuler ANF 40 (color: green) But there are no original substitutes that fall under the Toyota recommendation, where there is no mandatory color match! After all, there is a document: Basic national standards for coolants JIS K2234 (Japan) And a recommendation from Toyota, which says - antifreeze should be silicate-free based on an organic "corrosion inhibitor". Let's look at everything in order and decide what to do and how we should be =) no matter what the radiator or the engine is killed. Is it true that original red antifreeze is better than others on the market? it is clear that "under Toyota" they release a lot of all kinds of trash with supposedly original shildyk))). Mixing these types of antifreeze in the system is highly discouraged. Original Toyota antifreezes are of two types: and they are probably looking for the very codes or recommendations for replacing. But I want to dwell on the fact that winter is coming soon and many have not changed antifreeze yet. Been running it for years in several of our vehicles and family's vehicles.We have already discussed with you some codes for Antifreeze. The only Toyota the Zerex isn't in is my wife's '19 Corolla. My rig is 5.5 years old and I've done 2 DAFs in the last couple of years. ![]() I personally just don't like mixing different colors just because it's messier looking. With that in mind, it's better to stick with OE or Zerex Pink juice to keep the color consistent.though the color itself isn't that important. In my opinion catching coolant early and doing a simple drain and fill (DAF) on the radiator every couple of years will thwart most internal rot. No worries 's compatible with SLLC regardless of what people say. ![]() As for how long it can last? Generally speaking SLLC is around 5 years/100k miles.though some models are reported to call for 10 year/150k. But it does need to changed once in awhile to maintain proper corrosion protection. Most people just don't think about coolant. Click to expand.Time and mileage both play a factor.
