Volvo Expansion Tank Hose Keeps the Engine Coolant Flowing

By: Evander Klum

Friction from a vehicle engine's operation results to extremely high temperatures. To avoid the overheating of engines, automakers install cooling systems in automobiles. As larger and more powerful engines are getting manufactured, however, the cooling system technology needed to adapt to the demands of these new engines. In turn, car-manufacturing companies like Volvo created new cooling components. A clear example of such is the expansion tank.

An expansion tank is a container that provides extra storage space for the expansion of a coolant-a fluid used to dissipate heat. A Volvo Expansion Tank Hose ensures the optimum flow of coolant as it connects the vehicle's radiator with an expansion tank. An expansion tank is sometimes called coolant reservoir or overflow canister.

When engines heat up, the coolant consequently expands. Without the expansion tank, however, the coolant will just flow out of the cooling system and get displaced to the ground. are crucial in engine cooling systems. Without these components, coolant is not delivered to overflow canisters and cooling systems become very ineffective.

Aside from containing the coolant that has expanded with heat, the expansion tank also makes the cooling system more efficient by eliminating the air bubbles from the coolant. Coolant without air bubbles absorbs heat much faster. When the engine is sufficiently cooled, a vacuum in the cooling system sucks back the coolant through the Volvo Expansion Tank Hose. A properly functioning cooling system does not lose any coolant as the tank hose completes it as a virtually closed system. Even if the level of coolant in the expansion tank rises and falls, the radiator remains full all the time.
