I would think you would have much better results by dumping that hot water directly into the engine as coolant.

On modern cars with fuel injection there isn't much time for the fuel to cause condensation and cool the intake manifold. Thats IF the fuel even touches the intake manifold. Most designs have the injetors mounted in the head, so the fuel is injected after the manifold.
