Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2002 oldmobile Alero has failing intake manifold gasket which allows coolant to leak into engine. Estimates to repair are over $800 and after researching the fact that tens of thousands of others have the same problems with various GM vehicles manufactured from 1995-2003 I'm at a loss as to why this hasn't been taken care of. GM released bulletin 03-06-01-010 in which it suggests replacement of a "new design intake manifold gasket" which was changed to "improve the sealing qualities of the gasket". if there was no problem with the original there's no need for a replacement. GM is unwilling to repair this yet it affects 3.1 and 3.4L V6 engines of some 14 different GM models not to mention a similar affliction with the 3.8L.
