How the temperature gauge work in alfa romeo?

The temperature gauge in an Alfa Romeo, like in most vehicles, operates by monitoring the engine coolant temperature. It uses a temperature sensor located near the engine or in the coolant passage, which detects the coolant's temperature as it circulates. The sensor sends this information to the gauge on the dashboard, where it displays the temperature level, helping the driver monitor the engine's operating condition. If the engine overheats, the gauge will indicate a high temperature, prompting the driver to take action to prevent damage.
