2010 Ranger temp guage
So I am having an issue where the temp gauge will work normally for a bit and jump right to cold. When this happens I also lose A/C.
I have already replaced the thermostat and still have the issue.
Any idea what could be causing this?

The Ranger 2.3l DOHC Duratec engine didn't use an ECT(engine coolant temp) sensor, it uses a CHT(cylinder head Temp) sensor.
This is what tells the computer the engine temp, computer then sets the dash gauge for that temp.
I would check its connection and possibly replace that sensor.
Have a look here for where it is: Ford ranger Ford: Where is the coolant temperature sensor located
Losing the AC would happen if computer thought engine was overheating or didn't know the temp

For anyone needing to change out the CHT you will need a 19mm/ 3/4 deep socket to remove the sensor.
I found that out the hard way.

19mm/ 3/4 deep socket to remove the CHT sensor (what Socket woudl work?)
"EDIT -- found an older Craftsman 3/4 that fit over connector"EDIT
- Engine Light on Solid,
- Sporadic/Intermittent Temp gauge dropping off to left with no readings (Sometimes, it works fine, RPM's boost a bit, Temp gauge stops working (Goes immediately to left, AC stops)
- AC Not working when Temp Gauge drops
- Also noticed this happened once when a Bump was hit while driving
- Car Bucking *thought it might be a Transmission issue for a Bit.
Tks..
