Yes Ford has done that with their gauges for a long time, probably kept a lot new cars out of the shop for warranty repairs.

The engine has never increased tempature when driving even with the AC on to over a sustained 80 mph. In my case something in the cooling system has failed.


I am guessing my radiator didn't clog up in a year, the coolant is still green and no signs of rust in it and this problem started suddenly too.

...my next step is the fan clutch. (probably pretty tired after 145,000 miles anyway) I will get one and bolt and try it out on the way home.

I'll let ya'll know,
