If you notice your temperature gauge needle moving irregularly or communicating an inaccurate temperature, unreasonable to current conditions or without symptoms, it may be defective.

One possible cause is an air lock in the cooling system. If this does not reduce the overheating, turn on the heater as high as it can go. Conversly, a stuck open thermostat will result in the engine not reaching operating temperature and no heat.

As a solution, you need to level up the coolant and make sure there is no air in between, and you should stop facing the issue temperature gauge high but car not overheating.
