Your Engine has a upper and lower intakes the 3100(3.1L) and the 3400(3.4L) engines both had lower intake gasket problems.Coolant runs between the 2 heads thru the intake lower portion during the cooling cycling of the engine cooling system which involves your radiator,water pump,hoses,ETC. The black plastic and rubber coated gasket crack after a period of time and need to be replaced.

Usually intake has to do with the induction system, as in intake manifold , The intake manifold can have several types of leaks, the intake can have a vacuum leak, oil leak, coolant leak or a combination of any of the before mentioned....hope this helps,
