We now offer a accurate temperature sending unit for many Pontiac Olds & Buick vehicles. Months of research were devoted to this project in order to provide our customers with sending units that have the original-type terminal connection, housing and resistance (thermistor); resulting in an accurate gauge reading. They screw right into the 1/2" pipe thread hole (as original). Although these do not have a exact appearance as the original, they are very good replacement. This is for models with Rally Gauges (not dummy lights).
Both auto part's stores and GM/Delco do sell replacement temperature sending unit, but they do not produce an accurate gauge reading in vintage cars. This is because sending units from an auto part's store and even GM, are only a generic replacement; often requiring a new, matching gauge or re-calibration of your original gauge.
