i wonder if I can get any help on this since I am at 191K miles and having this done now. i am glad to see they released this.New Special Coverage on the emission reduction fluid tank reservoir due to the issues with the heater elements. Looks like GM is moving through the emissions system piece by piece...... (Note: This also applies to the 6.6L Duramax Express, Savana, Silverado, and Sierra.)
