Temperature sensor removal
I have a 2007 Uplander. 3.9. Temperature sensor is located on drivers side front below the throttle body.
I removed the throttle body for more room. It takes a 3/4 deep socket but I can’t get a ratchet down to remove. I tried a 3/4 spark plug socket but not enough room to get that on the sensor to break it loose.
I’m lost
Do they make a special tool to remove? Don’t know what to do.

I've owned my Uplander for only a couple of months so I can not speak from experience. However, the Mitchell service info states to remove the exhaust crossover pipe. If that looks like it is in the way then maybe it has to be done. I know where I live removing exhaust components is a scary prospect because of rust. I wonder if it is possible to use some combination of extensions and swivels to get in there?

Temperature sensor replaced
I fixed the problem. Used a 3/4 crows foot and short extension on a 3/8 ratchet. It took a while because you could only move a little bit at a time.
Good to have small hands. The crows foot would hit the edges of the motor so the positioning between the ratchet and the crows foot was critical. Didn’t have to remove the exhaust.
We’ll see if that corrects the problem.

Conditions that gave error
I received an error message on my dashboard that said AC turned off the protect engine. The temperature gauge dropped to 0. Nothing showing on the temp gauge.
I read it was the thermostat so I changed that out.
Just pulled the lower hose, drained it and replaced.
Started it up and the temperature gauge only went up 1/4 way. Van did not overheat and heater was working properly. Driving it again ended up giving me the same error message with AC off and temperature gauge dropped to zero.
I figured that the temperature sensor was reporting back to the ECM about the cooler reading and replicated the error message.
Once I changed the sensor, temperature gauge went back to normal at a 12 o’clock reading and everything was fine.
Hope this helps others.
