Remove the wiring and using a deep 1 116 socket remove it and replace it with a new one. When the coolant goes through the heater core it gets cooled off enough that when it returns the thermostat closes again momentairly. So the temperature goes up and the thermostat opens again and then it goes back down.

The ECT sensor is also a culprit for the excessive reading you can test the sensor using a multimeter and a boiling pot of water. My temp gauge was well under 210 driving down the highway then all of a sudden it jumps up past 210 between 210 and 260. I pulled over and felt around the engine and it wasnt even hot.
Then I got back into my truck and a few seconds later the temp gauge jumped back behind 210. Car temp gauge goes up and down when idling it says its overheating but the vents blow cold air will go down when I blast the heat after a couple seconds. Also does it driving normally it will just go up untill in the red and stay there car never actually overheats but im worried it.

If the needle goes to about the middle of the gauge that means the engine has reached normal operating temperature usually between 180 an 210F. It goes up quickly after starting then stabilizes. Youll notice that the temperature of the air coming out of you.
May 12 2018 1 hi all Tonight while driving along my car started to drop its temperature on the gauge. It was fluctuating gradually down and then back up over the course of a 200 mile journey but didnt make a noticeable difference in performance. It never dipped below 70 or raised above 90.
