The hyperspherical close-coupling method has been used to calculate electron capture cross sections for$C^{6+}$+H collisions for energies from 1 keV/amu down to 0.1 eV/amu. Total electron capture cross sections and partial cross sections to n=4 and n=5 states of $C^{5+}$ were obtained. For energies above 500 eV/amu our results agree with the semiclassical molecular orbital calculations but disagree with the more recent semiclassical atomic orbital calculations. For energies below 3 eV/amu the electron capture to n=5 becomes dominant and at energies below 3 eV/amu the electron capture cross sections show the Langevin 1/v dependence.
