Electric water pump for Volvo Engine coolant pump OE 30751700 Bomba de agua del refrigerante del motor

Product Description:

Engine coolane water pump
OE NO.:  30751700 31293303

Applicable vehicle type: For Volvo

The automotive engine cooling water pump is the core power component of the engine cooling system. Its main function is to provide circulation power for the coolant, ensuring that the coolant continuously flows in the engine water jacket, radiator, and pipelines, thereby removing the excess heat generated during engine operation and maintaining the engine within the optimal working temperature range (typically 80-105°C). The performance of the cooling water pump directly affects the engine's heat dissipation efficiency, fuel economy, and service life, and it is hailed as the 'heart of the engine cooling system'.

The water pump within a vehicle's engine cooling system performs several critical functions, significantly impacting the engine's stable operation and longevity:

• Maintaining Engine Temperature: The primary function of the water pump is to circulate coolant, removing heat from various engine components and transferring it to the radiator for dissipation, thereby keeping the engine within its optimal operating temperature range.
• Preventing engine overheating: During operation, combustion generates heat that elevates engine temperature.
• Circulating the cooling system: The water pump creates a continuous circuit for coolant throughout the engine cooling system, encompassing the engine water jacket, radiator, heater core, and other components.
• Providing cooling capacity: Different vehicle models require varying flow rates and head pressures from the water pump.
• Extending engine lifespan: Maintaining the engine at normal operating temperatures reduces thermal stress and wear, thereby prolonging the engine's service life.
