The reason your temp guage in the expedition doesn't move is because they are calibrated that way. I'd bet big money that if you put an aftermarket guage on a new car it would read much different than the factory guage. Reason is, that if the guage was accurate it would mean more people bringing there car in for service. Come to think of it, mabye I should just take the guage out. Then my cobra wouldn't run hot anymore, right?

I still would like to know how hot is too hot. I did switch to a higher pressure cap so my ride doesn't throw up as quickly!
