Low Coolant level Light 2000 Lumina

where is the sensor on the 2000 Lumina?, It's not in the bottle like on previous models.

Mounts to the radiator, just below the cap. It just pushes in and is held in place with a wire clip. Two wires in the electrical connector. Here's a picture of it: http://www.autozone.com/autozone/catalog/parts/partsShelf.jsp?categoryDisplayName=Cooling+%26+Hea ting&fromType=parts&fromString=search&parentId=63-0&currentPage=1&filterByKeyWord=low+coolant+sensor&isSearchByPartNumber=false&navValue=16301719&categoryNValue=16399999&fromWhere=&itemId=1719-0&displayName=Sensor+-+Radiator+Coolant+Level&searchText=low+coolant+sensor
