2012 Ford Edge 2.0 Cooling Issues

[BigPappa574]

Hey Guys, 

 

First post.  I have a on going issue w my Edge.  While driving, especially highway, the temp goes up to around 220.  Temp gage stays in the middle.  As soon as I let off the gas and coast.  Temp drops right back to 208ish. It has a new thermostat, and water pump.  Turbo was replaced a month or so ago.  I have drain and refilled it with the vacuum filling tool twice to confirm no air is in the system.  The only visible coolant leak is right under the drain.  I believe the pitcock needs replaced.  Its only one or two tiny drops on the ground.  I do have another one on order from Ford. Any help or direction is appreciated...

You suspect the loss of coolant is the petcock, but could be the issue discussed in the below thread.

 

How are you measuring the temperature?

Thanks for the reply,

 

I am checking the coolant temp w live data, along w my aftermarket radio.  They both read the same.  It is not setting any codes.
