English · machine-assisted draft

Community name for Volkswagen’s water-cooled, horizontally opposed four-cylinder engine family used in Vanagons. Gerry’s technical index covers 1.9 L and 2.1 L versions and year-specific service topics. A January 2004 archive thread describes an owner’s 1983 1.9 L Waterboxer running roughly when cold but normally after warming up; it records the symptom and discussion, not a universal cause or fix. Identify the engine code and model year before using parts or service information.
