DRFTEM Posted January 18, 2010 Share Posted January 18, 2010 Ok well I just changed out my thermostat and coolant yesterday. The lower thermostat housing had a coolant leak. So I removed it and re-sealed it.I then reconnected everything. I ran all the air bubbles out but now my gauge is reading that my car is hitting 250. So i freaked out thinking the thermostat must not be opening. So i pulled it back out and boiled some water. I then tested the water temp with a cooking thermometer and the thermostat opened. So I then ran the car untill it started reading it was overheating. I stuck the cooking thermometer into the radiator and it only read about 140 but the gauge was reading 250. What kind of resistence should I be getting through the sensor when at operating temp?Also what kind of voltage should i be getting through the single wire?

stravi757 Posted January 18, 2010 Share Posted January 18, 2010 check the contacts between the sensor and wire or replace the sensor. I had the same problem and replaced. its worked fine since. Quote Link to comment Share on other sites More sharing options...
Cheesecakepiebar Posted January 19, 2010 Share Posted January 19, 2010 It sounds like the sensor to me too. I had to pull off the thermostat housing and when I put it back on the temp gauge didn't work at all. I tried cleaning the connections with no results. A new sensor fixed the problem.
