Review: U may want this OEM part. - Was replacing the housing unit and although the new housing unit had a temp sensor with it, some reviews said their computer did not like that sensor. So I ordered this AC Delco sensor and installed with new housing unit. Have had no problems so far.

**Q: Will this fit in a 2014 chevy sonic lt 1.4 lt engine? also does this replace the sensor at the bottom of the radiator?**
