Applicable vehicle type: For Volvo

The automotive radiator hose (also known as a cooling hose or coolant hose) is an important component of the vehicle's cooling system, used to circulate coolant between the engine and the radiator. These hoses are typically made of reinforced rubber with an internal layer of steel or nylon braiding to withstand the high temperature and pressure of the coolant. The radiator hose ensures that the engine maintains an appropriate temperature during operation, preventing overheating and thereby protecting the engine's performance and lifespan.

Radiator hoses are widely used in the cooling systems of various vehicles. Their primary function is to connect key components of the cooling system, including:

• Hoses between the engine and the radiator: The upper hose transports the high-temperature coolant generated by the engine to the radiator for heat dissipation, while the lower hose returns the cooled coolant back to the engine. These two hoses are the core components of the cooling system, ensuring continuous circulation of coolant between the engine and the radiator.
• Hoses between the engine and the heater core: In addition to the radiator, some radiator hoses are connected to the engine's heater core, providing heat exchange for the vehicle's heating system. These hoses divert hot water from the engine to the heater core, where it heats the air inside the vehicle before being returned to the engine for cooling, thereby enabling the reuse of engine waste heat.
• Connections to other auxiliary components: In some vehicles, radiator hoses are also used to connect components such as the expansion tank, thermostat, and water pump.

In summary, radiator hoses play the role of "blood vessels" in the automotive cooling system, promptly removing and dissipating the heat generated by the engine while providing a heat source for the heating system. This ensures that the vehicle maintains good thermal management under various operating conditions.
