It was not until Chapter 25 (or Season 3 Episode 5 if you prefer) that Grievous had a showdown with Mace Windu. During the encounter, Windu used the Force to crush the chest plates of Grievous, severely injuring his lungs, and causing his now distinctive cough, which made its way into Revenge of the Sith.
