OEM Product
Thermostat was GM genuine and saved the day. Truck does not over heat anymore. Make sure to buy the seal as it does not come included. I will be definitely buying it again for my other truck.

Fit right in. These are always a great thing to change. Not very expensive and keep your vehicle temperature at a good place. When overheated, these are due for a change. Don't hesitate to change on your own, as well. Extremely simple, few screw and find location and how to videos on you tube.
