The Vanagon Dictionary

The accessible coolant container used to replenish the water-cooled Vanagon system as coolant moves between the pressurized expansion tank and the reservoir. It is not the pressurized expansion tank itself; verify the part by the vehicle's cooling-system layout.

• engine
• water-cooled
• cooling

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.

• water-cooled
• cooling

a substance used as antifreeze

• glycol
• coolant

Sensor that measures coolant temperature

• temperature
• sensor

device that circulates the coolant through the engine

• cooling
• engine

To remove air from the cooling system to prevent damage

• coolant
• maintenance

A chamber that surrounds the engine and carries coolant

• engine
• cooling
• jacket

a type of corrosion that occurs when coolant bubbles collapse against aluminum surfaces

• corrosion
• pump

A type of contaminant that can occur when silicates drop out of the coolant

• corrosion
• contaminant

A device used to recover fluids, such as coolant, from a system.

• fluid
• recovery
• vessel

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 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

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.

• engine
• air-cooled
• cooling

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.

• engine
• water-cooled

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.
