GM Genuine Parts 15-11125 (12674639) Water Pump Outlet Assembly with Thermostat

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.

Fit exactly as described based on specs. Worked perfectly after install. Happy with product

Perfect replacement, functions just like the original before it stuck open. Lost about 1/2-3/4 of a gallon of coolant during the swap.

I ordered this for my 2016 Silverado LTZ. I was having issues with the temperature barely getting above 150° most of the time it wouldn’t get above 140. And with winter rapidly approaching, I decided to give it a try. Installation was quite simple. This thermostat and housing is a one piece assembly unlike the traditional ones with an aluminum reusable housing, With this particular design you just throw the old housing away and install the whole new assembly. Everything fit perfectly the instructions were straightforward and boy What a difference in heat output. You can barely hold your hand in front of the vent now and she consistently runs at 205*F after if she warms up. Very satisfied.!!!

I replace the thermostat on my silverado 5.3 2014 165k miles 6 months ago, well i put on a murray brand from Oreilly auto parts because they did not had the AC Delco in stock, it lasted 6 months and well i tought it would be the water pump because normally thermostats wont get bad specially in 6 months, saw some videos on youtube and people where saying not to replace the thermostats on this truck with an aftermarket to always use oem, i order this oem thermostat and gave it a try before i try to replace first the water pump. Worked great it did not overheat no more, so dont risk it with aftermarket for the ecotec engines.

If your GM cooling fan stays on after you turn off your car most likely is the thermostat that is having issues. Fit my GM vehicle perfectly, direct OEM replacement so no guesswork on part numbers. The thermostat is already integrated into the housing, which saved me an extra step and a separate purchase. Install was straightforward, seals were solid right out of the box, and no leaks after a few weeks of driving. Solid quality for the price.

excellent

This was a direct fit replacement for my 2015 Silverado 5.3L engine. Worked perfectly and fixed the truck running cool situation. Just make sure you remove old gasket from original T-stat housing which is usually stuck to the aluminum surface or it’ll leak.
