...There's been many reports of the new Toyota Pink causing leaks in water pumps. Not sure what the reason for this is, or maybe it's just a fluke. I know that "officially", Toyota says Pink is backwards compatible with Red, but that could just be corporate marketing in efforts to consolidate products and make it easier for their service centers....
I've posted before on this board that I'm skeptical of the anecdotal reports of Toyota water pump failure, attributed to or stated caused by Toyota SLL pink AF. Not long ago member KingCake posted a related imo TSB posted
HERE that would appear provide an alternative explanation by Toyota to those alleged pump failures.
As for the thread resurrection, I didn't see any new information that changed information already covered in this thread. Toyota Red and SLL Pink are alike in that they are both Asian PHOAT AFs. The LL red is the older shorter service interval AF that comes as a concentrate, and it seem uses at least one different inhibitor(sodium benzoate), than newer SLL premix. Information posted previously says SLL pink uses sebacate as an inhibitor, and has the newer longer service interval Asian PHOAT used by most Asian vehicles now.
When it comes to MSDS sheets, for readers here it's fairly common knowledge that they are not a reliable source of every component of a product, in this case AF. We know about the differences in Peak Long Life and Peak Global Lifetime because Peak has said the difference in at least one email reply to a member and posted here. Also Peak goes out of it's way to say no 2eha in PGL in it's advertising. And Peak has said in the past that it's LL contains 2eha.
As for SLL pink being backward compatible to the LL red, Toyota says it is. I suppose one can attribute that to some kind of corporate conspiracy to put all their vehicles under one application. However afaik, Toyota Red is still sold for those that prefer to use what was originally spec'd and don't mind using the older shorter interval Red LL. Which I see nothing to indicate it has changed from that recommended service interval. So if one doesn't trust what Toyota says about SLL backward compatibility, use the red LL.
Just as fyi, like the previous poster I've been using Peak Global Lifetime concentrate from Napa in an 01 Tacoma for 3+ years now with good results, no issues. Still has original radiator.
