A system that assists the driver in parking by steering the vehicle into parallel and perpendicular spaces

Volkswagen engine with cylinder banks at a 10.6-degree V angle, allowing for a single cylinder head

Small, flat washers that help to absorb thrust loads on the front bearings

A type of filter that allows oil to bypass the main filter and flow directly to the engine.

The component that regulates airflow into the engine and the switches that monitor throttle position

Gaps between the piston rings, which must be offset to prevent oil from entering the combustion chamber

A ring-shaped component that provides a seal between two parts, such as the cylinder head and engine block

Gaskets used to seal connection between cylinder head and exhaust manifold

Exhaust pipe located before the rear silencer in Vanagon/T25, excluding Syncro models

A rod connecting the piston to the crankshaft, allowing the piston to move freely up and down in the cylinder.

A protective cover for the positive terminal of a generator or alternator

A switch that signals the engine computer when the throttle is in the idle or full throttle position

Original type of tire used on VWs through the mid 1960s, with plies that run diagonally from one bead to the other.

A type of electrical connector with a 6.3 mm spade shape and shielding for protection

A sealed or low-maintenance lead-acid battery design intended to reduce routine electrolyte checks; its condition, terminals, and charge may still need inspection.

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.

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.

An engine that rejects heat directly to moving air rather than circulating liquid coolant. Gerry’s spark-plug reference separates bus applications by engine code and period: ED/GD/GE for 1975–1979 and CV for 1980–1983, including California models. A May 2002 Gerry discussion titled “83 Air Cooled - Production dates” concerns an owner’s September 1983 Westfalia and the difficulty of finding comparable 1983 examples; it is a period-specific production question, not a universal fitment chart.

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.
