Question about Ford Cars & Trucks
I believe they are located in the intake manifold somewhere. Make sure the one that tells the computer the coolant temp is ACTUALLY giving out the correct temperature. I had a bad one one time in a 1993 Ford F-150, 5.8L....... no check engine light came on but hard to start. The bad sensor was telling the computer it was 32 degrees F when it was almost 80 degrees outside.!!
Garbage in=Garbage out.
Here is a video link from Youtube. There are 2 sensors, 1 for the guage and the other tells the on-board computer how hot/cold the coolant is. The one for the guage has 1-wire and the other one has 2 wires.
Hope this helps, ask more if you need to. What kind of problem are you having? No heat inside? Guage needle not getting into the normal area?

the coolant temp sensor is located: Under hood, driver side, upper engine area, below
valve cover, mounted in cylinder head

It’s located on the driver’s side of the engine on top /side of the head.. midway.. I don’t think you need to remove the engine cover to see it.. if it is the correct one it will have a dark green top.. the bad version has a black top… but they can all go out to lunch on you if old enough.
To replace.. make sure the car is cool..
You need a hood tool.. or small pair of pliers to remove the retaining clip that holds it in place.
Place a rag under and around it to catch the coolant.. you will lose less than a half a cup.. if that.
Pull the retaining clip back toward you.. try not to drop it.. (another good reason for the rag)
Wiggle the sensor.. pop it out.. and replace with the new green top one make sure you clean the area well.. and when you reinstall the new one that the c clip goes back on straight or it will leak.
Once you see the part out of the box.. you will understand how it works
Start the car.. check for leaks.. run until warm with the heater on.. top up the coolant overflow bottle with distilled water.. (if more than a half a cup.. you should mix the proper anti freeze and distilled water and then top up with that)

located under intake in water crossover pipe,you can access the sensor by removing intake chamber box,then pcv hose connected to the block,the connector is orangeish 2pin,use a 19mmdeep socket on a 3/8 ratchet to get it loose,make sure engine is cool,also make sure there is a new brass washer with your new sensor,sometimes the old washer comes off when removing the sensor,sometimes it sticks to the pipe,some coolant will escape so make sure to top it off
