Just bought a 09 c30 r with 82,000 on the car I was wondering what type of cooent to use, dexcool ? whats in my c30 is orange. Also are the overflow tanks prone to cracking and leaking since they are pressurized.

Thanks for any posts, happy to own a c30

 

I don't think dexcool is a choice for this cooling system. I use Prestone with ethylene glycol and make sure it's flushed every 2-3 years. Not sure if it fits the c30. Don't forget to completely flush the old coolant as the dexcool should not be mixed with a different coolant. You may want to use some pressurized air in the block drain hole.
