Sierra 1500 SLT 5.3L V8

  • Automatic transmission
  • 46,439 miles

2014 Sierra 1500 SLT has been properly serviced, mileage is 46439, never abused, after shutting off engine electric radiator fan continued to run for 5 minutes, investigation found antifreeze overflow tank leaking orange milky fluid, no low fluids alarms or overheating alarms, transmission fluid full and clean, engine oil not registering on dip stick, oil and filter changed with Mobil 1 2000 miles earlier, I called GMC dealer in Chillicothe, Ohio and I was advised to contact GM Roadside Assistance and have it towed to this dealer, after receiving my truck dealer called next day telling me that I apparently had my oil sabotaged I debunked his suggestion, he then said that the radiator was probably disintegrating internally, he also stated that the damage would not be covered under the GMC warranty, 46439 miles is not what I should have expected the life of a radiator would be on a 2 year old vehicle that was purchased new, I'm waiting on the cost now, by the way I don't see how an engine oil cooling system is not part of the power train of the vehicle
