i actually found the zerex g-05 at a local parts store after looking everywhere... did the flush because i had to replace the water pump... after getting the old coolant out i noticed it was the pink/orange color but the zerex is the green coolant... is that ok or should i drain it out and put the havoline dex cool in....

Zerex says that Dex-Cool is the appropriate coolant for late-model Porsches. Dex-Cool is orange, G-05 is yellow (except for factory-installed G-05 coolant in Chrysler/Dodge/Jeep, which is orange) and the traditional IAT coolant is green. Check these out:

Supposedly the G-05 coolant is better, though that has yet be proven. Either way, Dex-Cool is the recommended coolant for these cars. I am probably going to run G-05 in my BMW when I swap that out in the near future, however.
