Hey Brian==it is in the fromt of the intake manifold. Drain the rakiator then remove it and install the new one. GoodluckJoe
That would acually be the fan sensor. There is a coolant temperature sensor on the right hand end (looking from the front) of the engine. When it fails, the idle speed goes a bit goofy and the engine tends to ide fast. The gauge will also do some interesting things as well.
This is best done with a cold engine but can be done hot, just be very very careful and make sure the pressure is off the cooling system but once you have released it, put the cap back on tight.
The sensor has 2 wires, yellow and black, and is clipped onto the sensor with a snap connector. Be careful not to pull the wires but to pull the sensor off with the plastic holder. Once the wires are free, then you can remove the old sensor.
Make sure to prepare the new one by wrapping Teflon tape on the threads to seal it. That works best. Remove the old sensor and quickly put the new one into place and finger tighten. Once it snuggs up, then finish tightening it into place.
Make sure you replace the wires otherwise it will at least set an error code or 2.
Good luck.
