Is it possible to replace this Heater Hose tube without major engine components having to be removed? Or is this a difficult to get to task that will require professional automotive mechanic? Guidance is greatly apprecaited. The local Chrysler dealership quote said: " Heater hose tube leaking where it goes into lower intake manifold. They included replacing the intake manifold, bolts, and gasket???? Seems improbable that the manifold is bad? Thanks!
