ACDelcoGM Original Equipment 15-11073 Engine Coolant Thermostat and Housing Assembly

Glad to spend a few extra dollars for the ACDelco thermostat. A quality piece, and the rubber O-ring stays in place during installation. A two hour job to install on a GMC Canyon (requires left front wheel and fender well removal), no installation surprises. Old thermostat was stuck open. The new thermostat now regulates the temp just over 1/2 on the gauge. Very pleased.

Good thermostat, good price. Like everyone else, I got a P0128 in my 2005 Chevy Colorado 5cyl. I don't think my original thermostat stuck open, but rather lost its calibration. Driving around with the scan tool connected, I was topping out at a steady 165 degrees everyday. Gauge showed around the 1/4 way mark. I think my normal was just below the 1/2 mark. This new thermostat is said to be a little hotter and it is. I'm now at 196-200. Gauge slightly above the 1/2 mark.Install was ok. I did not remove the tire. I had enough room to work around it. I did remove the wheel well piece. 10mm and some extensions and a universal to remove the stat. If I used my little 1/4 inch drive set, I probably could have gotten away without the universal joint. The bolts were not super tight, I could easily loosen them without putting any muscle behind the wrench. The factory clamps were a bear to release with channel locks. I removed lower hose from radiator and left it still attached to thermostat. Just guide it out from the wheel well. Remember the path you took. I purchased a new hose too, didn't want to take a chance that I might need to cut the old hose. I assembled new hose and stat to the same position as the old and guided it back into position. Holes lined up and hose was in a good position too. I used a little piece of tape to hold the bolts to my wrench for reassembly, and that was it. Factory clamps were the biggest pain of the job. I had regular hose clamps on hand, but just reused the factory clamps. No way they will ever snap or leak. If you choose not to mount the hose to the thermostat outside the truck, you might want to remove that tire so you have more room to struggle with the clamp.The check engine light went out on the next morning drive as soon as it warmed up, so don't reset the code if you are coming up on inspection in a heavy handed emissions state like NY.

La pieza es exactamente la publicada y perfecta para mí Chevrolet Colorado, resolvió mi problema de calentamiento del motor haciendo la marcación de la temperatura como debe ser. Pieza original.

Needed a new one for my 2008 Hummer H3. This one fit and works great! I'm very satisfied. I'm giving it a one star for "Easy to Install" because where it is in my truck is an odd place and was a PITA to install
