#engine

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

A liquid used to regulate engine temperature

Sensor that monitors the coolant level in the engine

A critical cooling system component around the engine compartment

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.

Proportion of antifreeze to water in the cooling system

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.

System responsible for regulating engine temperature

The housing that contains the crankshaft and camshaft

System that removes gases from the engine crankcase

Main shaft that converts reciprocating motion into rotary motion

Collection of components that make up the crankshaft

The amount of movement of the crankshaft in the crankcase

A seal that prevents oil from leaking out of the crankcase

Bearing that supports the crankshaft in an engine, guiding it during rotation

A pulley that drives the serpentine belt

Corrosion occurring in crevices or areas where moisture accumulates

A seal for the cylinder barrel

A gasket that seals the cylinder head to the engine block
