Hi,

It is right near the thermostat housing (upper radiator hose at engine). It's hidden behind the AC compressor. That's why you are having a hard time finding it.

If you look below, I attached the directions specific to this vehicle for the removal and replacement of the sensor. Take a look through them and let me know if you have any questions.

Take care and let me know if this helps.
