ALERT: DexCool Coolant! READ!
*LINK AT BOTTOM*
Okay guys, I was doing a little research on the internet in regards to the Corvette temperature fluctuating, mainly when in idle. I came across some very interesting information!
It seems that there is a potential Class Action Lawsuit against GM due to their use of "Dexcool" engine coolant. It corrodes aluminum engine parts and drivetrain parts and potentially causes thousands of dollars in damage. This could have something to do with the engine coolant fluctuation.
Our Corvettes come built with Dexcool in it and several websites advise AGAINST CHANGING COOLANTS, that doing so may cause more damage to the vehicle. DO NOT MIX the coolants either, that will cause greater damage.
According to the service manual that comes with the Corvette, it does at one point advise that it is okay to do a 50/50 mixture with clean, drinkable water. Consult your manual for better details.
I'm hoping to bring some potential answers to light for you guys, I know i'm new around these parts, but I couldn't possibly withhold this information.

Using Dexcool must caus irrepairable damage as I've had it in my car for well over 100k and the hoses/waterpump still look like new.
Those people need to blame the dealerships that're screwin em and quit looking to GM.
My personal fav quote:
"The product in vehicles coolant systems deteriorates aluminum parts in the engine," Ronald said. "The intake manifold, cylinder heads and timing chain cover are all made out of aluminum. My vehicle needs all these parts replaced."
His problems worsened. "The motor has coolant in the oil and oil in coolant," indicating that the head gasket is leaking. "This is the second time this problem has occurred."
What a tool.

I have heard if you change as you should(I think 5 yrs. is too long).That there is no risk.This comes from mechanics that I know who have worked on hundreds of G.M. products.If you mix it,i.e. Jiffy Lube top off or leave it in too long then you have problems.....

Duh?....Class Action nonsense.
Horse Pucky! Lawyers continue to collect names for potential class action lawsuits from people claiming Dex-Cool damaged their car.
Prestone and other suppliers offer a Dex-cool which is an organic based mixture in addition to the Propolyene Glycol based stuff. All have anti corrosion additives and can be mixed together although not recommended. Prestone and GM have experienced engineers and I doubt that they would fill the Corvette at the factory with a defective mix. They do however use Kentucky Tap water to mix with the coolant so I drain and refill with distilled water and 50% Dex. Darn stuff is always clean although I do refill every two years as I am a typical Obsessive Corvette owner. The average driver idiot out there probably does not even know where the Radiator cap is located.My 2 cents.
