Why is my temperature gauge jumping around?
One common cause is a defective thermostat, a component that is inexpensive and easy to replace. Other causes of a fluctuating temperature gauge are a failing radiator fan, insufficient coolant level and a leaking cylinder head gasket. A failing radiator fan will be erratic.
Why does my temp gauge keep going up and down?
If all instruments are acting up, that would be the culprit. If only one is acting up, it is most likely the sensor or the wiring for that one circuit. When it is coolant temperature, I think air bubbles can cause some fluctuating readings.
What do you mean by temperature gauge is fluctuating?
Temperature gauge is fluctuating, sometimes showing overh… Q: Temperature gauge is fluctuating, sometimes showing overheating.
How does the temp gauge on a Silverado work?
The temp. gauge fluctuates constantly between normal and 210^ in cool weather (40^ & below). Also during accleration it will rise to 210^ and drop back down, never staying at a constant temp. It constantly moves between normal and 210^, exempt during summer time it stays steady. I replaced the t-stat 3 times, having no affect.
What is the temp on a 1995 GMC k1500 Z71?
I have a 1995 GMC K1500 Z71 350 TBI. The temp. gauge fluctuates constantly between normal and 210^ in cool weather (40^ & below). Also during accleration it will rise to 210^ and drop back down, never staying at a constant temp. It constantly moves between normal and 210^, exempt during summer time it stays steady.
If your temp gauge is not staying stable, it keeps going up and down and you have PO300 code, you will have to troubleshoot the problem until you find a solution.
