What does a red coolant temperature light indicate?

The red coolant temperature light serves as a critical warning indicator for the engine's operating temperature. When this light activates, it signifies that the coolant temperature has risen beyond a specific threshold, indicating potential overheating. The correct interpretation of this red light is that the temperature exceeds 230F, which is a critical level that requires immediate attention to prevent engine damage.

This warning helps operators recognize that an overheating engine could lead to severe mechanical failures, including engine seizure or failure of other key components. Understanding this warning is essential for ensuring the safe and efficient operation of the vehicle, as well as extending the longevity of the engine. Proper responses to this indicator may include stopping the vehicle, allowing it to cool, checking coolant levels, and assessing for any leaks or mechanical issues.
