Your Dodge Ram 1500’s engine coolant protects your truck against overheating and ensures that it runs at an optimal temperature.
When the coolant level drops below the minimum level, the truck’s “GAUGES” light might illuminate.
2. Faulty Engine Coolant Sensor
If your coolant level is fine, there might be an issue with your truck’s coolant sensor.
A bad coolant temperature sensor will send the wrong signal to your truck’s computer, which may turn on the “GAUGES” light.
3. Bad Coolant Reservoir Cap
A cracked or loose coolant reservoir cap can also cause your truck’s “GAUGES” light to illuminate.
4. Faulty Instrument Cluster
If the “GAUGES” light is the only abnormal indicator on your dash, the issue could be with your instrument cluster.
The instrument cluster is the panel that houses all of the gauge and indicator lights on your dashboard, and it can become faulty or malfunction over time.
