The 3.8 GM V6 is prone to blown intake gaskets much more than blown head gaskets. The blown intake gasket causes a loss of coolant which in turn causes overheating and a blown head gasket. The problem exists with most 2000 to 2003 vehicles equipped with the 3.8 Liter V6. There were defects in the upper intake manifold gasket, throttle body nuts, and the throttle body gasket.
