The intake Manifold Gasket is leaking. This appears to be a common issue with these cars.

Seriously... another stupid GM problem of a car. After changing the power steering fluid, my car decided it was necessary to flip on the "Low Coolant Level" light. Definitely annoying considering it doesn't stay on... it flashes. I check the coolant EVERY day to see if it's a slow leak or something... but it's full! I don't get why the light is on, but it's the most annoying thing to have a light flashing in your face... not to mention distracting, especially when driving at night.

I have a 1999 Grand Prix and the low coolant light is staying after I it has been filled with antifreeze. I changed the thermostat because it started running hat and now the light is on about half the time.

my wife and i have a 1999 Pontiac Grand Prix GTP and we have hardly had any trouble with it at all just the minor things that comes with having a vehicle but anyway we have a new problem now and its that the low coolant light stays on even when you put antifreeze in the radiator and in the reservoir and it smokes right at the reservoir. We thought we had the problem fixed b/c we went and bought a new radiator cap for it but apparently that wasn't the problem.We need to know if their is anyone out there that has had the same problem so we can go about getting it fixed or we need to know if their is a recall on this certain car so we can get it to the dealership and get it taken care of. We are running out of options on what to do so please let us know. Thanks
