    Well, did you replace your defective coolant temperature sensor (LINK)?

    I tried another sensor, but it's still having the same issue. My gauge goes up to about 250°, while my Sniper is showing the temp about 180°. Once the fans kick in, both temps drop. The gauge is in the front manifold location, while the Sniper sensor is in the rear manifold location. I grabbed the upper radiator hose and my 180° thermostat was open when the Sniper was around 140°. I kind of find it hard to believe that two brands of sensors are bad.

    Now isn't the time to save money on a junkyard sensor. Standard Motor Products TX3 coolant temperature sensor. I know for a fact, that this CTS is accurate.
    May God's grace bless you in the Lord Jesus Christ.
