![]() 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. 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. A radiator cap that fails to hold pressure can result in coolant overheating because coolant under pressure has a higher boiling point. Subaru specifies a non-silicate, non-phosphate and non-amine antifreeze. The other possible culprits would be water pump, cooling fan or the rad itself. 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. ![]() How does this happen? Is this a problem? Is it worth complaining to the dealer - is there anything they would do about this or would they say it's normal?Įdit: I really appreciate how my newb questions were met with so many helpful suggestions, ideas, and useful information in a friendly way.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. Nothing unusual in how I've been driving it - mostly on the highway some in town. Oil on dip stick is quite clear still (see second photo). I haven't seen any coolant leak underneath, the engine exterior and everything looks clean. My old subaru did burn coolant so I was used to checking it frequently. Everything I've read is that a good engine should not be consuming coolant. Now, the coolant overflow reservoir is only an inch above the "low" mark (see image below). I've driven for a month and put 1500 miles on it. According to Subaru the new Coolant must NOT be mixed with any. This coolant is blue in color and every bottle has a big S in the middle and a red cape on it. When I bought it before driving home I checked the coolant overflow reservoir and it was about an inch below "full". The new 2008 Subaru WRX STI and all of the 2009 model year Subaru’s use a new type of coolant dubbed by Subaru as Subaru Super Coolant. ![]() I've had my 2023 forester for exactly a month.
