My Porsche had alien blood

[Ebell914]

Thanks guys!!! I am pretty sure this is original coolant now that you say all this. The car is exceptionally original and in very well maintained condition, which is why I was so confused to see it green. Either way, I will flush it thoroughly before putting in Porsche pink.

Just curious though- is the original Porsche green compatible with the newer Pink?

copied paste from Pedro's garage website:
"I chose not to go with the Porsche coolant.
If you do the same, be sure to get phosphate, silicate and nitrite free product such as Prestone."
so according to pedro, certain collants can be mixed with the OEM.

Yes, they are compatible.
My car had muddy coloured coolant, which my indie and I concluded was a mixture of the original green stuff and the newer pink product that happened when the dealer replaced the original expansion tank and just topped the system off.
When I replaced the water pump and thermostat a couple of years back, I replaced it all with fresh pink G13 Volkswagen coolant.
