Who makes subaru super coolant1/13/2024 ![]() ![]() Same deal with installing - install the radiator itself first, then install each fan onto the radiator in the engine bay. ![]() In other words, don't try to pull the whole thing out together (radiator with fans still attached). As a fellow Suby owner, a big tip on doing this job is remove the radiator fans before attempting to remove the radiator itself. You should consider just replacing the radiator wherever the car is, it's not that hard. The only replacements that meet the requirements of Japanese auto manufacturers are factory coolants, Valvoline Zerex® Asian Vehicle Anitfreeze/Coolant, and Motorcraft Specialty Green Engine Coolant-which, as far as I know, are the only P-OAT coolants available in the US market.Avoid the conditioner, it's not worth it and may not even stop that kind of leak. G-05 is a particularly bad match to Japanese vehicles because it contains silicates. I am not saying that they don't exist but merely that every time I have checked they list nothing specific about the additive package other than sodium benzoate or NJTSRN QT1 which is a NJ registered name for a proprietary Peak "long-life" coolant package.Īt any rate, neither G-05 nor ANY Peak coolant is suitable for use in most Japanese vehicles because they do not contain phosphates. Mazda introduced FL-22 in 2005, replacing a first generation P-OAT coolant which was the factory fill in my 2003 Mazda MPV.Įvidently Ford determined that FL-22 was superior to G-05 in Ford/Mazda engines relying on Japanese technology.įor the record, I have never seen a bottle of Peak Long Life or Extended Life coolant that specifically lists 2-EHA on the label. ), Ford used G-05 (Motorcraft Premium Gold Engine Coolant) as the factory fill in Ford-Mazda engines. This assertion was made long before Ford introduced Motorcraft Specialty Green Engine Coolant, a P-OAT coolant similar to Mazda FL-22, as the factory fill for engines jointly developed with Mazda. Moreover, Peak technical consultants are also quoted in online boards issuing blatantly false misinformation such as the assertion that Mazda FL-22 coolant (Mazda's version of CCI's second generation P-OAT coolant) is merely a relabeled Motorcraft product. Some Peak technical consultants have been quoted on some boards (including this one) as admitting that Peak Long Life coolant contains 2-EHA but Peak has never published any statement in print on the web to my knowledge affirming this. The issue regarding 2-EHA in Peak "long life" coolants other than Peak Global Lifetime (which Peak advertises as 2-EHA free) is murky. Peak "long life" (Global Lifetime, Long Life, Extended Life) coolants are not appropriate for most Japanese vehicles because they contain no phosphates (according to Peak advertising). Most recommend both because the proprietary coolant formulas from the dominant Japanese coolant company, CCI, rely on silicate-free, phosphated organic acid technology (P-OAT). G-05 contains silicates and no phosphates it is not a suitable coolant replacement in Japanese vehicles where the manufacturer specifically recommends either a silicate-free coolant or a phosphated coolant. ![]() If you have an Asian vehicle use the Xerex P-OAT coolant. You don't use "universal" oil do you? Quit guessing already. Is using WM coolant that tempting? I am not using any "all makes and models" coolant just like I wouldn't use all makes and models auto trans fluid. You know what is in it, you know it works excellent and it is just as cheap as the "all makes-all models" stuff. If you don't even know what is in the universal coolant, why use it? Why not use a coolant that you know the chemistry and you know the performance history? That is why many of us always recommend G-05. In any case, if your conclusions are correct about ST and Peak EL, it would sure make finding a GL clone easier and less expensive. I know color is not a good indicator of coolant type but Peak LL has the same yellow green as ST and Peak EL. I recently did a flush series with the Peak LL on my Altima. I have believed that Wally's Peak Extended Life, only available at WM, was the same as Peak Long Life sold at many auto parts stores. You might have some doubters on that one. It would also mean that ST and Peak EL does not contain 2eha, which some on this board detest. ST and Peak Extended Life are readily/easily available at Wally World at very reasonable prices, especially as compared to Peak GL. No to doubt you, but, if that is true IMO you have exposed a real coup. No other coolant I have seen (except some other private label coolants akin to Superteach) lists NJTSRN QT1 as an ingredient. If you read the respective ingredients labels, they all list the same proprietary additive package NJTSRN QT1, registered as a trade secret with the State of New Jersey. Super Tech appears to use the same coolant formula as Peak Extended Life which appears to be the same as Peak Global Lifetime. ![]()
