A type of seal made from copper, used in coolant systems

a type of coolant formula that does not contain phosphates

The pressurized tank in the water-cooled Vanagon cooling circuit that accommodates coolant expansion and provides a fill and bleed point. It is separate from the low-pressure coolant refill reservoir; the names are sometimes confused in parts listings.

substances added to coolant to prevent corrosion, such as sodium nitrite or sodium benzoate

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.

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.

a substance used as antifreeze

Sensor that measures coolant temperature

device that circulates the coolant through the engine

To remove air from the cooling system to prevent damage

A chamber that surrounds the engine and carries coolant

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

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

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

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.

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.

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.

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.

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.

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.
