Location of cooling fan sending unit 1999 cadillac deville?


If you are refering to the Engine Coolant Temperature (ECT) sensor,it is located on the right rear of the engine below the exhaust gas recirculation (EGR) valve.

HINT: If your Deville is equipped with the analog instrument cluster and the temperature gauge is working, or if you have the digital instrument cluster and the driver information center (DIC) has been diplaying messages telling you that the engine is hot, the problem with your engine cooling fans is NOT the sensor.

Why is my car leaking oil its a 1995 cadillac deville sedan with 108k on it


because it is 15 years old. Engine seals dry out and deteriorate over time. Just a guess, but I'll bet the oil is coming from your main seal or valve cover.
