Nissan Altima Engines by Year

The Nissan Altima engine catalog lists four engine rows across the catalog years. The examples span model years from 1999 through 2022, with the engine code and year range identifying which listed engine applies to each period.

The examples show KA24DE for 1999–2001, QR25DE and VQ35DE for 2002–2018, and KR20DDET for 2019–2022. Since two engine codes share the 2002–2018 range, use the specific vehicle’s year and engine details to identify the right entry; the catalog examples do not show which trims or configurations use each engine. For a figure not listed here, confirm it on the door jamb or in the owner’s manual.
