Default Coolant Type for 991.2 GT3 RS

Hi guys, does anyone know which type of coolant comes in the 991.2 GT3 RS?

I know it is not a common question and that I may just go a purchase straight ahead at the dealership some bottles of an undisclosed coolant type, but just as we know that the car uses 0W-40 engine oil: I would like to know which coolant type comes with my car!

Is it:

a) Inorganic Additive Technology (IAT),
b)
Organic Acid Technology (OAT), or
c)
Hybrid Organic Acid Technology (HOAT)

Regards,

Edson.

O.A.T. Formula is what you need
Specifically; ASTM D3306, BS6580, VW, PORSCHE 774F SPEC
NITRITE, AMINE and PHOSPHATE (NAP) FREE and LOW SILICATE FORMULA

So, it is safe to say coolants G12+ and G13 from the VW group are direct alternatives right? G12+ is ASTM D3306, BS6580 and 774F spec as well.

Thanks man! I was wondering that VW coolant G12+ and G13 would be reasonable replacements? Those are ASTM D3306, BS6580 and 774F compliant. What do you think?

In my 991.1 GTS, I use Valvoline ZEREX G40, originally a BASF Glysantin formula.

You mean ZEREX? Any auto parts store that carries it. NAPA is where I got mine.
