🌡️ Enhanced ACDelco Professional 19322820 Engine Coolant Temperature Sensor for Improved Performance Review

Sensor shown with copper disc. You should delete the photo or make sure the sensor comes with the washer. The sensor appears to be working, the test engine has not yet caught fire.

Well made part. Come on. Has not expired. And it was accurate right out of the box. Reduced price as the kit did not include a gasket (copper washer shown in photo) or thread sealant.
