Where is the temp sensor in a '94 Grand Prix 3.1 L engine and at what temp does it turn on the fan?

Asked by Oct 06, 2008 at 12:36 PM about the 1994 Pontiac Grand Prix 4 Dr SE Sedan

Question type: General

The passenger side radiator cooling fan does not turn on until the estimated temp reaches 225 to 230 degrees.  I find this to be a bit hot.  These temps are when the car is idling as in traffic jams.
