is a 3.1


KK:
Please see question # 8 at 'Q & A' page. the 95 ciera question for a pic of the coolant temp.
sensor.  Click on "read full ...." link for a pic of the coolant temp. sensor for the computer.(2-wire)
There is also a 1-wire sensor on the dr. side of the rear cyl. head for the dash gauge (if your car
has gauges).It has a green wire coming off of it. Either sensor is tricky to get to. Taking off the air
cleaner to throttle body duct can help.
Best way to reach rear sensor (1-wire) is with a short wrench.
