My 13,000 mile 2018 Macan Turbo needs it’s coolant topped up. What coolant should I use?

Honestly if you are just topping up a few oz worth just use distilled water. Not enough to affect the mix at any level of significance.

If more then only use Porsche pink OEM coolant. Sold as concentrate so you have to split 50.50 with distilled water.

Thanks very much. Good advice
