Worked fine on my 2004 Hummer H2. Seemed to stay at OE temperature.

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.

Very happy
Nice quality, real deal AC Delco part, not a knock-off. The termostat will look different than the old one you pull out, don’t worry it’s fine, this one looks different (does not have the 4 flow holes like your old one) because it was redesigned to work better, the water flows more evenly and with less stress on the water pump. This new one opens up way quicker than the old one that was in there which is nice.
