I recently changed my expansion tank on my 03 3.0i and my temp gauge is still inbetween the two middle white lines but past the dead center of the gauge is this normal? After doing a search on the forum someone said the gauge only has 3 points it measures cold,med, and hot not sure if thats true? I also have the old cap leaking but I never noticed it leaking before could this be from air in the system or just bad cap? I ordered a new cap last night just incase
