Supposedly the Zerex Asian Vehicle-labeled coolants are manufactured by CCI Corporation and/or CCI MANUFACTURING IL CORPORATION, so that would most likely be the absolute closest one can get to an OEM-specification engine coolant that isn't an OEM specification coolant for another Japanese manufacturer such as Mazda, Honda, Toyota, and Nissan.Ĭross-referenced Japanese OEM coolant part numbers: The additives were believed to be incompatible with the seals (and other components) and the water pumps failed and Honda subsequently released information to dealers and service departments recommending only Honda OEM coolants (made by CCI MANUFACTURING IL CORPORATION). Some failures were found to have occurred sometime after a majority of owners changed coolant to an aftermarket brand. Some forum threads about CCI coolants being crucial to longevity can be found by searching for Honda water pump failures.
Lots of info, but the summary is that CCI Corporation makes the engine coolant for practically ALL the Japanese car manufacturers and that the Japanese car manufacturers are very particular about what additives should be used in their engines. If you want to go a step further, you could try to find an aftermarket coolant with a similar makeup as the Subaru coolant as seen above.īut due to Subaru's history of cooling system issues on the older EJ engines, I personally wouldn't risk running a different coolant to initially save a few bucks. So the additives and corrosion inhibitors are proprietary to Subaru's engines, but I still believe that any ethylene glycol-based coolant with about a 50% dilution of distilled water will suffice. Hydrated inorganic acid, organic acid salts - Less than 5%.It is manufactured by CCI MANUFACTURING IL CORPORATION. Obviously, it is an MSDS (Material Safety Data Sheet), which shows how much ethylene glycol, water, and other substances make up the Subaru Long Life Super Coolant 50/50 Prediluted Antifreeze and Engine Coolant, part number SOA868V9270.

How long has it been since Coca-Cola's ingredients included cocaine?īy the way, the guys at Peak are very familiar with Subaru, Subaru coolant and Subaru coolant additive.Īs far as I'm concerned, Peak Global Coolant is the equivalent of Subaru coolant.Click to expand.The PDF attached is titled soa868v9270_msds.pdf It's like your doctor telling you it's OK to drink cola, but make sure the label says cocaine-free. Since nobody's made a non-amine coolant for years, we're running around looking for coolant that doesn't have something that isn't around anymore. In a brilliant marketing move, Subaru has managed to skirt the Magnusson Moss Act but telling us to only use a "non-amine" coolant. That company has told Peak Subaru's anti-corrosion package is 100% compatible with Peak's. The company that makes the anti-corrosion package for Subaru coolant also supplies Peak. The ingredients in Subaru and Peak Global are identical except for minor differences in the anti-corrosion package. Therefore, nobody lists non-amine on their coolant bottles. Virtually ALL coolants manufactured for the past few DECADES are non-amine. Peak Global is 100% phosphate and silicate free.
I spoke with a chemical engineer at the company that manufactrurers Peak Coolant last week for 40 minutes. They also refuse to tell anyone which brands meet their specifications.īy law, Subaru cannot mandate Subaru coolant unless they provided it for free. Subaru specifies a non-silicate, non-phosphate and non-amine antifreeze. I guess the question is now.for my planned coolant change next year (at 60K miles), should I stick with super blue Long Life or should I just do it with green Long Life? Either one, I will definitely add the Subaru conditioner. I could, however, tell that the blue coolant is still present in the system (at least being the majority) by looking at the color of the coolant inside the radiator. It could have been topped off with green in the past, or worst, it could have been topped with Yellow Prestone or other non-Subaru coolant. In fact, prior to knowing that my Forester originally came with blue from factory, I assumed that it came with green and already planned to do drain and refill at 60K miles (following the 30K miles interval).Īnother interesting point brought up on another thread is that.since I bought this car used at 50K, there's absolutely no way for me to know that my Forester's coolant has never been topped off with anything other than the blue coolant.
