Blue Coolant in 99 C2

[99C2_Riyanto]

Hi, does anyone have blue coolant in your 996 C2? I bought a used 99 C2 and it has a blue coolant in it. I asked a dealership about this and they said they have never seen a blue coolant from Porsche. I am curious whether anyone have the same coolant as mine and if not, whether it is safe keeping this coolant in the car.

Thank you much for any response.

Sure you're not looking at the windshield washer reservoir? :)

I'm guessing the previous owner mixed two different color coolants. I'm not sure what combination would yield blue though.

Sure :)

Actually, a dealership pointed it out to me during a PPI. An independent shop contradicted that though. He said he has seen blue coolant coming from the factory. I don't know whom is right.

Maybe if you mix the old (yellow/green) with the newer (pink) you get blue?

Pentosin makes a very good blue antifreeze used by some independent shops. ;)

Ive never seen blue coolant from the factory. As mentioned however, Porsche did change from green to pink recently.

Hmmm...as long as the coolant meets Porsche recommendations then it should be OK. If not then it a pain to purge and refill but a def must do. You should find out who added that anti-freeze and know what is in your car.

I know BMW and Volkswagon take blue coolant. Something special about it for the aluminum...I'm sure your ok though..

Thanks for all the replies.

My best guess is that the coolant was introduced to the car when the engine was replaced 4 years ago (under a different ownership). I'm pretty sure it's okay. The car never overheated during track days and I don't see any sign of rust. However, since I'm not sure whether this is a lifetime coolant, I'll flush it out after it reaches 5 years (meaning next year).
