overnight the needle goes about 1/4 inch past the line below the C on the gauge. While running the vehicle all day it never goes past 1/4 inch above the C. Would this be a gauge issue or could it be a bad sensor?
Temp gauge on dash cluster, the needle goes past the bottom line below the C on 2001 Ford Explorer Sport Trac
could be a gauge issue, do you know what temp the eng is when the gauge is at running temp?
i believe it is around 180 - 210
poss sending unit or gauge, try sending unit 1st its easier
thanks, will try that first.
