Soph –
I bought this coolant for a system clean/flush on my 2011 Corvette GS. After a rather physically challenging clean and flush of the system, this stuff went back in just like the factory stuff. Same color and service rating, including factory recommendation. After a year; no problems at all. Engine runs as designed & stays cool. On these cars, not keeping the cooling system clean or using coolant not approved can seriously hurt it. I once considered buying a corvette until I heard the horror story of how the coolant got into the transmission because a shop drained and refilled the radiator with a cheap substitute coolant. The acid ate the aluminum in the radiator cooler!
