Tempature Gauge Going Crazy
 
Hey guys, I've been having this problem for a while now and I can't figure what exactly is causing this. My temperature gauge works fine then randomly shoots past the overheating mark, then it shoots all the way back to 0 and my Check Gauges light comes on. I don't know if my thermostat would have anything to do with this or not. Or if I need to replace a sensor. I'm trying to make sure I don't have to go see a tech to get it looked at because we all know they try to nickel and dime us. If anyone knows what the problem could be let me know.

Thanks

It sounds like your thermostat is sticking closed. Might be worth throwing in a new one and see if that solves your problem.

If it goes right back down to cold then it's probably an electrical problem. Check the connections on the wires, then try replacing the sending unit.

The temperature sensor is next to the thermostat housing, I would first try disconnecting its electrical connector and cleaning it thoroughly as skeeter says above, then reconnecting it.

Ok, I'll check that first thing in the morning.

Just had the exact same problem, replaced sensor and a 195 degree thermostat. Problem didn't go away, on a whim I let it set and the next AM I disconnected the temp sensor. Drove untill it was at operating temp and repluged the sensor. Drove about 20 miles killed the engin picked up some supplies and started home. Problem cured. No more issues and that has been 4 weeks. Guage stayes right at the 195 mark, not the 210 mark.
