Nissan Altima Owners Manual: Engine coolant temperature gauge
The gauge indicates the engine coolant temperature.
The engine coolant temperature is within the normal range 1 when the gauge needle points within the zone shown in the illustration.
The engine coolant temperature varies with the outside air temperature and driving conditions.
