Hi,
I wanted to triple check the correct anti-freeze for use in a 2025 Cayman GTS 4.0, the handbook does not give the info and calling the dealer only give a Porsche part number with no spec, from my searches it would appear to be G12++ or G40 which meets the VW TL-774-G standard. I don't need any at the moment but I like to keep fluids "in stock" just in case.
Thanks
Eddie
