Upper radiator coolant hose OE 32249282 Radiator hose upper for Volvo Engine radiator upper water hose cooler hose

Product Description:

Radiator coolant pipe
OE NO.:  32249282 32249283

Applicable vehicle type: For Volvo

The upper radiator coolant hose is a critical component within a vehicle's cooling system, primarily connecting the engine block or cylinder head to the upper inlet of the radiator. It transports the high-temperature coolant generated by the engine to the radiator for cooling. Typically constructed as a hose, it comprises multiple composite layers: an outer weather-resistant rubber protective layer, an intermediate high-strength braided mesh or fibre-reinforced layer, and an inner corrosion-resistant rubber layer. This construction enables the hose to withstand temperatures exceeding approximately 100°C and operating pressures of around 300 kPa during coolant circulation. The upper radiator hose is a vital component within the automotive cooling system, ensuring the smooth circulation of engine coolant to maintain the engine's optimal operating temperature.

Compared to the lower radiator coolant hose, the upper radiator hose typically endures higher pressures and temperatures as it directly connects to the engine's high-temperature coolant output [cheezautoparts.com]. Consequently, the material selection and manufacturing processes for the upper radiator hose must adhere to stricter standards to meet performance requirements in high-temperature, high-pressure environments.
