So I replaced head gaskets and am looking for coolant for my 2002 Legacy and my local Subaru dealer no longer carries the Subaru coolant for the older models. I've done a ton of internet searches and have found 2 or 3 other brands recommended (Peak Global, Zerex Asian, Beck Arnley) but none of them are locally available (in concentrate)and I hate the idea of having to pay for shipping on something like this. I did find Zerex Asian locally but only in the 50/50 mix (which will cost about 80% more to do a complete re-fill since you have to buy 2 bottles!).
My (old) Subaru Long Life coolant (deep green) bottle spells out the ingredients; Ethylene Glycol, Diethylen Glycol, Soduim Benzoate and Potassium Hydroxide (and water, even though it is a concentrate). I see many other brands out there with the first two main ingredients and have to wonder if any of those will suffice (these are HOAT, if I understand correctly). I saw in a previous thread mention of Pep Boys OEM coolant and they do specifically mention it is OK for Subarus of this era. However, it also says it is borate-free. Is the missing borate something to worry about? I have a new bottle of Subaru Coolant conditioner that I may or may not use along with 6 Star MLS head gaskets.
At least I'm not too far from a Pep Boys...
