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: instrument panel is not working
Found the problem! The main cable going to the under-hood fuse box was rubbing against the metal bracket that the fuse box mounts on. Can we say poor electrical layout?? It had rubbed the sheathing off the cable and had broken one wire (the one supplying power to the instrument panel.) So I fixed that and cut a section of rubber hose and put it over the bracket to help prevent such events from occurring in the future.

GM has a problem with clusters but the government nor GM will do a recall on the clusters. Check ur local yellow pages for a Speedometer fix company , if u cant find one hit me back and I can find one for you.. In Houston we pay $250 for the service.
