1999 Cadillac DeVille Question: location of temp sensor
Answer #1Oakman September 17, 2009, 13:15Master
The coolant sensor on the northstar engine in your 1999 Cadillac DeVille is located on the back end of the rear head. Not very easy to get to as I remember. The cooling fans should come on at about 230 degrees.
