Temp gauge running hot
Hello world, I have a 2000 Subaru Impreza Outback Sport and the temp gauge reads hot automatically even on a cold start, we replaced both the oil temp sensor and cooling sensor and the thermostat and even replaced the radiator cap, she is not overheating and even burped the system, answers would be greatly appreciated to get the root of the problem, thank you

Have you read the computer to see if it's pulling a code?

Same issue in my '95 Legacy
The gauge stays in the middle when the car is on.
Even when only the ignition is on, it goes to the middle. Then back down when the car is off. Goes straight to the middle on a cold start, and stays there when warm and never moves (until I turn off the engine). I unplugged the coolant temp sensor (CTS) and turned on the ignition (not the engine) and the gauge went to the middle again. This also kicked on the cooling fans. Then I unplugged the temp sender unit (right next to the CTS) and the gauge still went to the middle again when I turned on the ignition. No codes. Haven't figured out the issue yet |

perhaps just a short in the gauge cluster? I suppose you'd have to get your hands on another gauge cluster from a junkyard and plug it in and see if the gauge behaves the same way?

Solved
Solved: the gauge was bad.
I replaced the single wire sending unit, this was not the issue for me. No need to buy a whole cluster, just pull the temp gauge off your cluster, then pull another from your local wreckers. Cost me $10 |

Mine does that but only if the thermostat is in. Once you remove the thermostat I have no issues. I still don’t know what’s wrong

?
Did you check the sensor for any breaks in the wiring?
