My engine gets very hot, and the fans turn on, but the low coolant light turns on even though it is filled up and I still have to turn my heater on to cool it down. What makes this happen?

Have you tried replacing the thermostat or having the cooling system flushed?

The next step is to replace the thermostat.

Let me know if it helps.
