Problem with lower intake manifold that has to be replaced due to bad dexcool. Dealership will not cover repair for vehicle.

This is my second Pontiac mini van with a leaking intake manifold gasket. The 1994 started leaking at 60K miles, my current van a 2003 is leaking at 45K miles. In my 94 van the engine failed at89K with religious oil changes and coolant flushes. My Montana also has had coolant and oil changes often. I know of others with the same problem.
