The rich galaxy cluster Abell 2204 exhibits edges in its X-ray surfacebrightness at $\sim 65$ and $35 {\rm~ kpc}$ west and east of its center,respectively. The presence of these edges, which were interpreted as sloshingcold fronts, implies that the intracluster medium was recently disturbed. Weanalyze the properties of the intracluster medium using multiple Chandraobservations of Abell 2204. We find a density ratio $n_{\rm in}/n_{\rm out} =2.05\pm0.05$ and a temperature ratio $T_{\rm out}/T_{\rm in} = 1.91\pm0.27$(projected, or $1.87\pm0.56$ deprojected) across the western edge, andcorrespondingly $n_{\rm in}/n_{\rm out} = 1.96\pm0.05$ and $T_{\rm out}/T_{\rmin} =1.45\pm0.15$ (projected, or $1.25\pm0.26$ deprojected) across the easternedge. These values are typical of cold fronts in galaxy clusters. This,together with the spiral pattern observed in the cluster core, supports thesloshing scenario for Abell 2204. No Kelvin-Helmholtz eddies are observed alongthe cold front surfaces, indicating that they are effectively suppressed bysome physical mechanism. We argue that the suppression is likely facilitated bythe magnetic fields amplified in the sloshing motion, and deduce from themeasured gas properties that the magnetic field strength should be greater than$24\pm6$ $\mu$G and $32\pm8$ $\mu$G along the west and east cold fronts,respectively.
