sensor location

Assuming coolant sensor is the culprit, as the fans come on when A/C is turned on, but don't come on when car is sitting at a stop light. Where is the sensor? Looked all around the thermostat housing (gooseneck), and no luck. Girlfriend's car. 95, v/6 supercharged. Auto parts gy and I searched for a few minutes and never located it.

It can take a surprising amount of time for the fans to turn on while sitting at a light. The low speed fan won't kick on until 212 degrees F. Perhaps find someone that can scan the car's PCM to watch for the coolant temperature sensor data, and watch the fans when it gets up there.

But, the sensor itself is located under the throttle body/above the exhaust crossover above the transmission case tucked in to the side of the lower intake manifold. Has a two-wire plug plugged into the end of it.

EDIT: That sensor very VERY rarely goes bad.

Yea, I get paranoid about my fans kicking in all the time. Leave the car parked while on and watch the temp gauge. Mine ended up kicking on at like 215

I think I will use my Infrared Thermometer and see what the temp of the coolant going into the radiator is and then see is the fan(s) come on,,,,,
