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.

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.

A temperature-responsive valve in a water-cooled engine's coolant circuit. It regulates coolant flow as the engine warms; the correct part and installation are engine-specific.

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 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.

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.

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 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.
