I got this "Low coolant" to come on after the car shut down. I took a look at the coolant level and topped it off. I have had to top off the coolant 1 time before last year and it turned out that the water pump was going bad. I hope that it's not going bad again!
Anyways, I don't see any leaks nor do I see any spots on the snow or garage. I had to add about 1/8 of a gallon to the radiator to fill up the expansion tank.
Any thoughts?
