It was my understanding that the cracked tab was a result of the thermostat cycling too often and causing stress fractures.

Has anyone been successful with getting the V6 repaired under this TSB? I have a 2014 4.3L V6 at 59k with a cracked radiator tab. I started noticing my temperature gauge going up and down recently, and I turned the truck off over the weekend and the fans were running for a few minutes afterwards. I popped the hood and noticed my coolant reservoir was dry as could be. I ended up filling it with a gallon and half of coolant. I have coolant residue on the top of my radiator on the drivers side with a cracked tab. I am curious to know if anyone was successful in getting this repaired with the V6. I have an appointment with the dealer for later this week, but the adviser at Chevy's 800# said my VIN was not included with these TSBs.
