Just changed the thermostat and temperature gauge sender on my 97 Zetec. The temperature gauge goes just a little bit into the red (maybe a milimeter).

Does it take a while for a new thermostat to 'settle in'? Or could I have put the wrong kind in there? (I went to pep-boys, looked up the model/year in a book and picked one off their rack).

Is it normal for the needle to go that high?

Any input is appreciated!

thanks,
Tom
