I had the same problem with my 2001 Pontiac Montana and the intake manifold gasket. This is a major problem with these 3.4L engines, if you are in the states I'm pretty sure there is a class action law suite against GM for this. I had my manifold gasket replaced and it was about $1000 CAD. You need to get your vehicle looked at right away as this could cause major engine damage, coolant will leak into the engine and soon enough you will be replacing that too. Good Luck

SOURCE: Fuel gauge needle way past full,
Most likely this is the common 03-05 Cavalier instrument cluster problem where the stepper motors on the cluster's circuit board go out. It can be fixed, check this page for more on how to get it taken care of - Cavalier fuel gauge broken
