NISSAN B1010-VC225 TB48 Water Pump Assembly

The genuine NISSAN B1010-VC225 (alternative part number: 21010VC225) water pump (Water Pump TB48 / PUMP ASSY-WATER) is an essential component of the engine's cooling system. This premium-quality OEM part ensures a continuous and optimal flow of coolant between the engine block, cylinder head, and radiator, preventing engine overheating and maintaining the ideal operating temperature.

Technical Features and Construction

• High-Quality Materials: Durable cast housing and precision-machined internal components provide maximum corrosion resistance and extended service life.
• Optimal Flow Dynamics: The impeller design delivers maximum fluid delivery with minimal cavitation, even at high engine speeds.
• Reliable Sealing: Equipped with heavy-duty mechanical seals that prevent coolant leakage around the shaft.
• Precision Bearings: Durable, low-friction bearings designed to withstand axial and radial loads, reducing operating noise and vibration.

Role and Importance of the Water Pump

The primary function of the water pump is to circulate coolant through the closed cooling circuit. Heat generated by the engine is transferred by the coolant to the radiator, where it dissipates into the surrounding air. If the water pump fails, coolant circulation stops, which can lead to rapid engine overheating, a blown head gasket, or catastrophic engine block damage.

Typical Symptoms of Failure

• Coolant Leaks: Moisture or traces of antifreeze around the water pump housing or underneath the vehicle.
• Abnormal Noise: Squeaking, groaning, or metallic grinding sounds coming from the engine bay, typically caused by worn bearings.
• Engine Overheating: Temperature gauge needle rising into the red zone.
• Unstable Coolant Level: A steadily dropping coolant level in the expansion reservoir.
