And I'm not sure the purpose of a 180° stat in these cars. I had one in my car for awhile and the temps were the same. Once the engine warms in the summer, the only thing that drops it is the fans. And in winter it would probably just mean it will take longer to get the car warm. I reprogrammed my fans 15 degrees lower and now it runs cooler of course. If someone can explain the point of a cooler stat on stock pcm I'd be interested to hear.
