Why does my temperature gauge stay on hot?

Common reasons for this to happen: Low Coolant: The first suspected cause of your temperature gauge maxing out is low coolant.

The needle may be stuck in the hot range (this can happen after overheating the engine), or a stepper gear in the gauge may be damaged.
