A controllable mechanical motor vehicle coolant pump includes a rotatable drive shaft co-rotatably connected with a coolant pump wheel, a transverse housing surface extending transversely with respect to and surrounding the drive shaft, a cylindrical inner slider support surface radially surrounding the drive shaft, a control slider which is axially shiftable with respect to the coolant pump wheel so as to control an effective discharge flow cross-section thereof, and a push-out pressure chamber. The push-out pressure chamber is arranged between a slider bottom wall of the control slider and the transverse housing surface, is defined at one axial side by the transverse housing surface and radially inwardly by the cylindrical inner slider support surface, and is pressurized to generate a push-out push force which pushes the slider bottom wall toward the coolant pump wheel. A first housing element defines the transverse housing surface and the inner slider support surface.
