Dash Lights
 

There is a light on the far right side of my dash, it almost looks like a radiator. could anyone tell me exactly what it is for?? It is on all the time. radiator is full and all that to. We put a new aftermarket radiator on the car, is that what caused it?? any help is appreciated.. Thanks guys

Radiator overflow is empty. Even though the radiator is full, you need coolant in the overflow tank as well.

There is a 'low-coolant' sensor in the plastic bottle. If the bottle is 1/2 full, then the sensor is stuck, or inop.
