Basically an OEM part!
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.!!!
