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.

Stick with OEM, you won’t be disappointed
OEM is the way to go on GMT800’s… keeps my temperature just where it should be. Fits like OEM because it is OEM. Just a heads up, it does not come with the rubber gasket so buy a felpro while your at it!
