Just recently noticed my temperature gauge hasn’t been reaching its usual levels when driving up hill, it’s registering much lower than usual, displaying temperatures more akin to rolling downhill in neutral in the winter time. After driving around for a while, up and down and around, with the gauge pretty much exactly in this same spot, i noticed that as soon as i turn the key to shut the engine, the temp gauge skyrockets into the near red zone, hot hot hot. Pull the key out, and sit there watching, it stays hot on the gauge. Put the key in and turn one click to glow the glow plugs, but not any further, and the gauge goes back down to the cool end of the spectrum.
Is my gauge fried? Are there other potential culprits?
