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.

A camper's rear bench seat that folds or rearranges to form the lower sleeping surface. The conversion mechanism and dimensions depend on the interior layout.

• camper
• bed
• interior

The camper interior cabinet assembly built around the sink and its water fittings. In some Vanagon Westfalia layouts it also contains or adjoins the refrigerator, storage, and electrical controls.

The exterior electrical inlet used to connect an equipped camper to campsite alternating-current power. Wiring, voltage, current rating, and supported appliances vary by market and model year.

• camper

A removable or swiveling table fitted to a camper dining area. The 1983 Vanagon Westfalia manual describes separate passenger-compartment and cab tables; mountings and storage differ across camper layouts.

A small radiator that transfers heat from engine coolant to air for the cabin heating system. Vanagons may have front and additional rear heat exchangers, depending on equipment and market.

• engine
• water-cooled
• heating

The front-mounted heat exchanger in a water-cooled Vanagon's engine-coolant circuit. It releases heat from circulating coolant to outside air. Air-cooled Type 2 buses do not use an engine-coolant radiator.

• cooling

The folding or sliding sleeping platform fitted beneath a camper pop-up roof on equipped models. It is stowed when the roof is lowered and is distinct from the lower rear bench bed.

• camper
• bed
• interior

The belt-driven pump that circulates engine coolant through the water-cooled Vanagon engine and cooling circuit. It is different from the small electric pump used to deliver water to a camper sink.

• engine
• water-cooled
• cooling

The small electric pump that moves water from an onboard camper tank to the sink faucet when the tank-water mode is selected. It is separate from the engine's coolant-circulation pump.

• camper
• water-system
• electrical

A heat exchanger that removes heat from engine oil. Air-cooled Type 2 engines use an oil cooler in the engine cooling assembly; design and mounting vary by engine. It is distinct from a Vanagon coolant radiator.

• engine
• air-cooled
• cooling

A hinged roof section that raises above a camper van to create extra headroom and, when equipped, access to an upper sleeping area. Roof construction, latches, and bed equipment vary among VW Bus and camper conversions.

• camper
• roof
• westfalia

An exterior hose inlet that connects a camper's water system to a pressurized campsite supply. The fitting and plumbing arrangement vary; the vehicle manual distinguishes this mode from drawing water with the onboard pump.

• camper
• water-system
• exterior

A fuel container and supply connection serving propane appliances fitted to some camper conversions. Tank location, capacity, regulator, lines, and supported appliances are installation-specific; use the vehicle and appliance documentation for operation or service.

• camper
• appliance
• fuel-system

The flexible fabric enclosure between a raised camper roof and the fixed vehicle roof. Depending on the design, it may include screened or closable openings; it is an enclosure, not a roof support or fall-protection device.

• camper
• roof
• canvas

An onboard tank that stores water for a camper's sink supply. Capacity, location, filler, vent, and drain differ by conversion; it is not necessarily a potable-water-rated tank unless the specific installation is documented as such.

• camper
• water-system
• interior

The drain pipe and outlet that carry used sink water out of the camper sink. Some vintage camper layouts discharge through an open outlet rather than a grey-water tank, so the installed arrangement should be checked on the vehicle.

• camper
• water-system
• plumbing

The housing around the engine cooling fan that directs airflow across the cylinders and cylinder heads on an air-cooled VW engine. Type 2 shrouds differ by engine and model year; this term does not describe the liquid-coolant radiator used on water-cooled Vanagons.

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.

In a Syncro drivetrain, a driveshaft decoupler disconnects the prop shaft so the front axle is no longer driven through it; it is not the front differential lock. A Gerry discussion on 16 May 2004 compares the original non-viscous-coupling layout, which used a driveshaft decoupler, with viscous-coupling Syncros while debating front-lock behavior. The thread is historical community discussion, not a retrofit procedure; identify the drivetrain configuration before interpreting parts or controls.

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.

The electronic control unit (ECU) is part of Volkswagen’s Digifant fuel-injection and engine-management system. Gerry’s 1986–1991 technical bulletin index distinguishes these applications from the earlier Digijet years. In a January 1999 list thread, an owner of a 1986 Westfalia reported that the engine quit after cooling-system bleeding and asked whether fuel starvation or a failed Digifant component was involved; the thread records a troubleshooting question, not a confirmed diagnosis. Check engine code and market before identifying an ECU.
