Hey guys, hoping to get some help from the community on this one. I can't seem to find the location of the coolant temperature sensor on the engine. Everything I could find on the Internet shows the location of the sensor on the previous gen, or the location of the sensor on a 2.5 non-turbo. Usually it's easily visible by the thermostat housing, but I can't seem to locate it on the 2.5T. To be fair, I haven't taken the battery out or anything, but I wanted to get an idea of where it is before I start ripping stuff out. Any ideas?

The part number of the sensor is SH01-18-840 if that helps.

Also check the link for the procedure. The thermostat has a pin that needs to be aligned in the right orientation.
