A molecular line survey towards the UC H II region G34.3+0.15 from 155.3 to 165.3GHz has been conducted with the TRAO 14-m radio telescope. Combined with our previous observations from 84.7 to 115.6GHz and 123.5 to 155.3GHz (Paper I), the spectral coverage of this survey in G34.3+0.15 now runs from 85 to 165 GHz. From these latest observations, a total of 18 lines from 6 species were detected. These include four new lines corresponding to ΔJ = 0, ΔK = 1 transitions of the CH3OH E-type species, and two new lines corresponding to transitions from SO2 and HC3N. These 6 new lines are CH3OH[1(1) - 1(0)E], CH3OH[2(1) - 2(0)E], CH3OH[3(1) - 3(0)E], CH3OH[4(1) - 4(0)E], SO2[14(1, 13) -14(0, 14)] and HC3N[18 -17]. We applied a rotation diagram analysis to derive rotation temperatures and column densities from the methanol transitions detected, and combined with NRAO 12-m data from Slysh et al. 1999. Applying a two-component fit, we find a cold component with temperature 13-16K and column density 3.3-3.4 ×10 14 cm-2, and a hot component with temperature 64 - 83K and column density 9.3×10 14 - 9.7 ×10 14 cm-2. On the other hand, applying just a one-component fit yields temperatures in the 47 -62 K range and column densities from 7.5-1.1 × 10 15 cm-2.
