OEM replacement thermostat. The AC on my wifes Cadillac XT5 would not work until the thermostat was replaced.

Fast shipping and the thermostat was exactly as pictured. UPDATE: I finally installed the thermostat this week in my new intake and it stuck 4 times causing the engine to reach almost 230° !!! I immediately brought the truck home and put the old thermostat back in and it works flawlessly. MY WARNING IS YOU ARE BUYING MEXICO GARBAGE !!!! Treat it as such which is where this is going right after I adjust it a bit with a hammer.
