I confirmed with the seller that it is 100% genuine gm and it functions perfectly, perfect fit for my 2014 Silverado 5.3, no leaks, no high temps, no low temps, can install yourself in less then an hour

I purchased this to address an issue with constant running radiator fan on 2014 Silverado with the 4.3L V6. It should be noted that the condition can be caused by either the thermostat or the coolant temperature sensor. Replacing either part involves draining and refilling the coolant, so replacing both at the same time could save time and coolant. Other than the annoyance that GM designed a huge plastic chunk where you cannot simply remove and replace a $20 thermostat, this part was an exact replacement for the original part. There were no fitment or operational issues. It was as simple as remove the old and install the new. Just be mindful to not over torque the screws or you will crack the part.
