Question on Boxster Flush Pink / Versus Green

I have a recently purchased 1997 Boxster, currently with about 49,000 miles. My low coolant warning light came on immediately the last time I went to start the car last week. I live in New England and it was between 30 and 40 degrees that morning, though I've driven in similar temperatures with no issues. Shut down and restarted, still flashing, so I parked it. I saw no puddles around the car where it has been parked, and the coolant appeared to be right around the Min mark on the tank, but looking at it again later it appears that it is indeed below Min. It appears the green coolant that this car would have come with has been phased out and the only thing that can be found around now is the pink one. What is in my car is green. I have not serviced my coolant system yet since I bought it, and I don't want to assume that what's in my tank from the previous owner is green Porsche coolant. Do I need to do anything aside from the instructions in the 101 Projects book for servicing the coolant system before refilling with the pink coolant? I just want to be on the safe side and ensure that there is no old fluid that might possibly react with the pink coolant. Thanks for all that you do for the Porsche community!

No matter how hard you try, he will never be able to get 100% of the old coolant out of your car's went system when you change the fluid. Although I don't recommend mixing colors, type, or brands of coolant, when you replace all the coolant in your cooling system, there is almost no way to avoid some mixing of the old coolant with the new coolant. In general, there isn't much to worry about. The linking light on your dashboard indicates that you have a low coolant level. Keep an eye on it – if the coolant continues to disappear without any obvious leaks, then you may have a head gasket issue to deal with in the future.
