5 stars… for now
This looks to be made of some lower quality metal than the original but the price was right and as an added bonus it appears to work just fine. Tolerances were perfect allowing it to mate up to the existing coolant pipe so I didn’t have to remove the fuel rails. The o-ring included on the mitzone pipe was great quality and fit perfectly on the GM pipe I left in the valley. Like everyone else says the bolts are too long but I just used the OE bolts to put it back in. Pretty happy with my repair so far, if it fails I’ll come back and change this review.

Saved me over a grand!
Bought this to replace a thermostat in a '19 Acadia with 35,000 miles! Kept getting reduced steering warning on dash. Was a pain to replace thermostat (designers need a swift kick!) but, saved me over a grand! Put almost 12,000 miles on the car now and (tap on wood) working like a champ! No leaks, no alarms. Took this opportunity to flush coolant system and replaced temp sensor while I had it apart!

Better than OEM in my opinion. And priced right.
I looked through the reviews before I ordered. I had a suspicion that the 1 star reviews were Inaccurate at best. Here is my Experianced. The thermostat and housing assembly was packaged so it would not be damaged from Shipping. It was an exact copy of the defective old OEM thermostat that was removed. The bolts supplied with the assembly were just 2mm shorter than what was removed. All went well with the installation. I did swap the o ring over to the old coolant pipe so it wouldn’t require the injectors to be removed. The operating temp now is 200-205 which is spec. No leaks no runs and no errors. Master Auto tech.

No oring
Great price but doesn’t come with oring. Need to purchase separately. At least mine didn’t

Fits perfect on my Cadillac xt5
The thermostat housing worked great on our xt5 cadillac. Much cheaper than the auto parts stores by a long shot. Great material easy to install and bolted up perfectly

Quedó perfecto.
Si solo necesitas el termostato sin la base, recomiendo que compres solo eso, ya que cambiar toda la pieza requiere de mayor trabajo de instalación y por ende más costo en mano de obra.
