Any body had problems with the coolant temp sensor leaking? Notice the last week or so coolant level drop from half way between min and max marks, to below min mark. Notice a pool of water from the bottom of the sensor. Or could it just be that the 'o' ring/seal is broken?

 

I had a similar thing on mine a few weeks back, the coolant was leaking from the thermostat housing. Bought the plug and o ring seal from Ford (FINIS 1150991), sorted.
