hmm ok but it s not only about the metal parts in your cooling system. Are oldskool gaskets and other composites (headgasket, waterpump impeller,...) compatible with the sebacic acid in the pink sllc? Anybody knows that? Just like 2-eha sebacic acid is moreorless like a plasticizer. To be safe I d choose a phoat based on benzoate and phosphates, like the old toyored llc, pentifrost a1, zerex asian.
Here in Europe, none of these are available. I could get Aisin ullc, which is a phoat. Asked techsupport about it containing 2-eha and was told it doesn t.
Anybody here knows if it contains sebacic?
