What does the indicator light with an arrow pointing down to a squiggly line mean?

Answer:

Answer

It's a GM product (I'm assuming) and it means that your coolant level is low. Although if it is full, it's probably a bad sensor (Rather common with Gm on that sensor). If you call GM, they'll tell you to gently hit the sensor and it should turn off if reservoir is full.
