Abstract: The bilocal correlator for finite-temperature gluodynamics is calculated in the instanton gas model. It is shown that the correlation length of vacuum in this model decreases when temperature increases. The results are compared with finite-temperature lattice calculations for the bilocal correlator. The instanton density and possible structures of nonperturbative vacuum are discussed.
