Montana LE V6

  • Automatic transmission
  • 88,000 miles

It seems that the Pontiac Montana has a continued issue with the Intake Manifold Gasket leaking and allowing anti-freeze into the engine. This continues to be an issue and GM does nothing about it, this is getting out of control. It always seems to happen when the vehicle gets over 80,000 miles.
