Four Seasons Engine Coolant Temperature Sensor Connector P/N:70016
Four Seasons 37281 a/c harness connector for the 1994-2005 Cadillac DeVille and other vehicles is the connector that joins the harness wiring to an engine coolant temperature sensor.
A cracked housing, a loose fit, corroded terminals or a coolant temperature reading that jumps around can mean this connector is worn, though the sensor itself or the wiring harness can sit behind the same signs. Look the connector over with the engine off and cool before you replace anything.
This connector is listed for a wide range of Cadillac, Buick, Oldsmobile, Pontiac and Saturn models, including the 2000-2004 Cadillac Seville and the 2002-2004 Buick Park Avenue. If your car is not named here, look up its year and model on the Buyer's Guide tab.
