It took a while to find the problem. I had to resort to taking it to the dealer and letting them troubleshoot it. It took them about a week and several conferences with Ford headquarters to determine that it was a cracked block near the temp sensor. It was a very small, hairline crack that would only open under the right circumstances and was small enough that it didn't cause the entire cooling system to overheat. The result and only solution was a complete engine replacement (long block) that cost me about $6K. Needless to say, I was extremely unhappy. This is my wife's car, which she depends on to haul around a bunch of kids during the day so my wife was the one who authorized the go ahead. I'm not so sure I would have spent the money otherwise. I was highly disappointed that Ford did not offer to even discount the work since it was obviously not caused by abuse. The vehicle had a little over 60K miles on it at the time. Of course, I haven't had any similar problems with the vehicle since this work was done and my wife is happy, so I suppose alls well that ends well (except my checkbook). To say that I'm soured on Fords and their customer service would be an understatement. I'm not sure that I'll ever buy one again due to their attitude that it was just my tough luck that this happened to me.
I hope this isn't what your problem is. It seems like testing the wires should be relatively simple if that is the problem, so you might try that next.

Thank you for responding. I'm sorry to hear of your troubles with your Expedition. Mine currently has 167,000 on its original engine, so I hope that your new engine will last you a while.
I have been concerned that maybe I have something major like a cracked block or a head gasket on its way out. These symptoms seemed so odd that I was hoping that this problem was some simple $100 fix and I'd be on my way. Considering how long we've had this truck, I'm probably due for something big

Yeah, I think my problem with that engine is actually fairly rare. There are enough of the 5.4L engines out there that if it was common, everyone would know about it and Ford would have fixed it. That was one reason that I was disappointed that Ford didn't step up and help out since it was so unusual. Best of luck to you in fixing your problem. I hope it's not too expensive for you.
