An engine that circulates liquid coolant through passages and a radiator to carry heat away. Gerry’s Vanagon spark-plug reference lists DH water-cooled engines with Digijet for 1983–1985 and MV engines with Digifant for 1986–1991. Verify engine code, market, and model year; this archived table is an identification aid, not a complete application chart.

Volkswagen’s electronic fuel-injection and engine-management system used in North American Vanagons from 1986 onward according to Gerry’s terminology FAQ. The archived FAQ distinguishes it from Digijet, which it associates with 1983.5–1985 Vanagons; Gerry’s technical bulletin index also lists Digifant topics for 1986–1991 models. Verify year, engine, and market before using system-specific parts or procedures.

Dehler was a German conversion company whose VW Transporter campers and business-van layouts appear in Gerry’s preserved terminology FAQ. Archive discussions make the model distinction clearer: a 1999 thread concerns a Dehler Profi conversion sighting, while a 2005 thread describes a rare Dehler Profi high-roof camper. “Dehler” therefore identifies the converter; Profi is a particular conversion line, not a separate Transporter generation. Confirm the exact build and year for parts or fitment.

• camper
• conversion

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.
