Why is it that the phosphates in the super long life, 2nd generation Asian P-OAT coolants are not depleted after 2-3 years, as they are in a 'conventional' Asian coolant?ДЄ better way of looking at is not that just the phosphate depleted (although that probably does happen) in the first generation 'conventional' coolant, so much as the inhibitor pack in total got depleted.

My thinking is the shorten interval is because if you don't get a full change and due to their premix, you may not get a 50% concentrate of new coolant. If the argument is you can't get a full change then that's more the reason to change the FF sooner anyway. I still don't buy into the 10 year FF service interval even if you did a complete drain, when they are cutting the service fill life in half. And plastic aluminum radiators did away with the need for molybdate and the azoles.

and that sebacic did away with the need for nitrate, molybdate, benzoate. I guess the bottom line is the 2 coolants types are functionally equivalent for all the Japanese brands. I've heard that Toyota LL has an additive for magnesium protection, but not sure where the magnesium is used. The long life ingredients of azoles and molybdate for solder protection and brass-copper radiators, the 2-phospho I think is a scale inhibitor, as is probably the calcium and magnesium salts, nitrate for aluminum protection. Yes what I said was a simplification to what I thought was relative. It is advertised (by Ford) as available in undiluted form. I would try to find Motorcraft Specialty Green Coolant which is supposedly identical to Mazda FL22 (a second generation P-OAT). Japanese OEM coolants are typically overpriced. Most coolant replacement procedures do not completely eliminate all of the old coolant. The reduced service life for second generation P-OAT coolant in replacement applications is reportedly based on uncertainties about contaminants that may linger in the cooling system. In addition, it contains an inhibitor chemically similar to benzoate, the organic acid used in conventional antifreezes.' It also contains sebacate, the organic acid used in most extended-life anti-freezes. It combines the benefits of OAT and phosphate (non-amine) chemistry, which establishes a semi-permanent protective coating on metal surfaces even if the coolant level is allowed to fall. 'SubaruвЂ™s branded antifreeze is a good example ofthe Japanese philosophy. I found the following description in, June 2006:

I agree with mechanicx that Subaru has historically used Japanese P-OAT coolants. Second generation Japanese P-OAT coolants include other organic acid(s) - perhaps sebacic acid - but I have not yet found a precise description. 'Fluid F is Toyota's Long Life red coolant, an organic acid based coolant containing benzoic acid, phosphoric acid, molybdate, azoles, 2-phosphono-butane-1,2,4-tricarboxylic acid, nitrate, dye, antifoam, and water soluble calcium and magnesium salts, but without water soluble polymer.'Д«enzoic acid is an organic acid. Here is a description from a patent application of the first-generation Toyota P-OAT coolant: But my research suggests that the formulas may be a bit more complex than mechanicx describes. I don't want to mix anything and cause problems.I agree that all first generation Japanese P-OAT coolants are essentialy the same and that all second generation Japanese P-OAT coolants are essentially the same. It looks pink to me, but I have nothing to compare it to (I believe that's the kind that has to be diluted, so maybe it looks pink after being diluted?), so I have no idea if the owner before me was using the TGLL or something else. Now I'm worried about what is in my car at present. I've been trying to find out what is an acceptable equivalent for TGLL and in doing so I also discovered that there is a difference between Toyota Long Life (red) and Toyota Super Long Life (pink).

I looked at the Owner's Manual and it calls for 'ethylene-glycol type coolant' and the Chilton's book is a little more specific, saying 'Toyota Genuine Long Life Coolant or equivalent.' He thought it might need Dex Cool, which he didn't have any of. He wasn't sure what type of coolant to put in so he took off the cap and it appears to have a pinkish looking liquid inside. I recently purchased a 2004 Toyota Corolla S and while inspecting it my mechanic realized that the coolant reservoir is empty.
