Ok here's my problem. If I drive for along period of time, like I work 55 miles from my house. By the time I get like 15-20 miles. My temp gauge starts reading almost into the red. However if I get stuck in traffic (stop and go) my temp goes down to normal. I change out the clutch fan and problem still there. Also when I get home and temp almost showing in red. I don't hear or see andy water boiling over. Does this mean my gauge is broke or what? Also I tried to buy a new temp sensor at auto zone and all they show for mine is a single unit with 2 plug-ins. Mine just has the single plug-in by the thermostat.
