With the Surface Detector array (SD) of the Pierre Auger Observatory we candetect neutrinos with energy between 1017 eV and 1020 eV from point-like sources across thesky, from close to the Southern Celestial Pole up to 60 in declination, with peak sensitivitiesat declinations around 􀀀53 and +55, and an unmatched sensitivity for arrivaldirections in the Northern hemisphere. A search has been performed for highly-inclined airshowers induced by neutrinos of all avours with no candidate events found in data takenbetween 1 Jan 2004 and 31 Aug 2018. Upper limits on the neutrino ux from point-likesteady sources have been derived as a function of source declination. An unrivaled sensitivityis achieved in searches for transient sources with emission lasting over an hour or less, ifthey occur within the eld of view corresponding to the zenith angle range between 60 and95 where the SD of the Pierre Auger Observatory is most sensitive to neutrinos.
