Product Description:

Heater water hose
OE NO.:  31274927 31338213

Applicable vehicle type: For Volvo

Heater water hose, also known as the car heater water pipe, is a critical connecting component of the vehicle's heating and cooling system. Its core function is to convey coolant, thereby enabling the transfer of residual engine heat to the vehicle interior for heating, while also assisting in maintaining stable engine operating temperature.

Core Functions:

• Heat Transfer for Heating: As the 'heat transfer channel' between the engine cooling system and the vehicle's heater core, the water pump pushes the high-temperature coolant generated by the engine operation through this hose into the heater core. When the blower blows over the heater core, the air is heated and then blown into the passenger compartment, achieving in-car heating and defogging.
• Auxiliary Cooling and Temperature Control: It belongs to a branch circuit of the automotive cooling system, capable of assisting in diverting coolant to prevent excessively high local temperatures in the engine, ensuring the engine operates within an appropriate temperature range, and preventing failures caused by overheating.
