A liquid filter suitable for motor vehicles which includes a filter head ( 11 ), a vessel ( 12 ) and a filter element ( 16 ) disposed within the vessel ( 12 ) sealingly separating an inlet ( 14 ) from an outlet ( 15 ) such that liquid from the inlet must flow through the filter element to reach the outlet. The filter element ( 16 ) has guide projections ( 27, 28 ) positioning the filter element ( 16 ) within the vessel ( 12 ). Prior to installation, the filter element ( 16 ) is preassembled into the vessel ( 12 ) and fixed in position by pushing the filter element ( 16 ) into an element guide ( 29 ), after which the preassembly is screwed onto the filter head ( 11 ). When the vessel ( 12 ) is unscrewed from the filter head ( 11 ), the filter element ( 16 ) slides out of the element guide ( 29 ) and moves axially upwardly to free a volume V. Liquid flowing into the vessel ( 12 ) from the higher regions of the liquid filter ( 10 ) can flow into this volume, thus enabling drip-free replacement of the filter element.
