Monte Carlo

  • 0 miles
I have had to repair/replace my cooling system twice, at my own expense. I own a 2003 Chevy Monte Carlo. Dexcool coolant which is the only coolant recommended for GM cars is all that I have used since I have owned the car (bought new). There is a recall on dexcool that is under litigation, however, my manifold is now cracked from the dexcool gunking my engine. Once again, I am stuck with the bill. GM is denying there is a problem, but there are other owners who have had this problem. Please help- I am out of money, and a car.
