I didn't know if this is the right board to post this, but does anybody know where the overhead temperature display, probe is located? Just wanted to know where and how accurate this thing really is. Plus minus 5 degrees? I have a Y2K F-150 XLT. Thanks!

 

NufTime,
It is between your driver side headlight & A/C condensier. it is part of your headlight loom.
4-D LOW

 

Pop the grey cover off that covers the top of the radiator and you'll see it right there just to one side of the latch (the driver's side, I think). There are about 8 of those little plastic plugs with the screw thing that goes in the middle to lock them in. Pop them out and remove the cover and it's right there.
