Gurgling noise detected behind center console of vehicle at approx 60K miles. Dealer did not find anything wrong. Now at 84K miles, dealer telling me that I need to replace heater core, radiator, and associated components due to defective coolant (dex-cool). This coolant was originally used by Chevrolet in 95 and 96 Blazer and is now known to break down and result in "mud-like" substance. Risk of over-heating is primary concern. I have found at least 10 other individuals on the internet with similar problems. This is not an isolated complaint. My main issue - Chevy did not detect the problem early enough even though given opportunity and now I am faced with a potential safety hazard and $1200 repair. Also, their coolant is know to be defective as per my conversation with 2 of their representatives. As a consumer, I do not feel as if I should pay for Chevy's mistakes. I am looking to your organization for help in investigating this problem.
