jras312 Posted June 11, 2017 Share Posted June 11, 2017 Shortly after I bought the car last fall I did head gaskets and timing belt, I had everything apart and was cleaning things up here and there trying to make her reliable again, noticed there was a resistor installed inline with the wire that runs from the temp gauge to the sensor. It obviously wasn't stock to I just removed it and reconnected the wire how it's supposed to be. Ever since I did all that work the temp gauge has never gone above where it reads in this pic. I've installed a new OEM thermostat, OEM temp sensor, and even a new OEM gauge in the dash cluster. Nothing has changed. I grounded the wire to check the gauge and it pegs to the MAX just like it should. So why would there be too much resistance not allowing the needle to reach where operating temp should be? Also, it's in the 90's today in Iowa and the needle still won't go any higher. What else can I check? I've been battling this for far too long for such a simple thing like the dang temp gauge.
