Consumer complaints about DexCool in GM Engines

Consumer complaints about DexCool in GM Engines: "Jeffrey of Edison NJ (3/5/03):
At 78k miles, we experienced coolant leakage and failure of the intake manifold gasket on our 1996 Oldsmobile Cutlass Supreme. Repair cost was over $900. It appears there is a problem in GM vehicles of this vintage, with possible correlation to the DexCool coolant which GM requires us to use in these vehicles."
