Why is my low coolant light on?
40

Asked by freedom Feb 20, 2017 at 08:08 PM about the 1999 Pontiac Grand Prix 2 Dr GTP Supercharged Coupe

Question type: Maintenance & Repair

My low coolant light is on and
won't go off. The car isn't
running hot. It still has power.
The reservoir has water in it
and so does the radiator.
