B1M10MA70A Nissan PUMP ASSY WATER, Price: 125.23$, Weight: 2.2kg

Heavy‑Duty Engine Coolant Pump for Nissan Platforms

This OEM‑grade water pump keeps your engine at the correct temperature under load, traffic, or long hauls. It is engineered for tough commercial use and off‑road duty, delivering reliable coolant circulation for stable performance and long engine life.

Why you need it ❄️

The cooling system depends on constant flow. This pump moves coolant through the block, head, and radiator, preventing overheating, detonation, oil breakdown, and warped components. It protects gaskets, turbo (where fitted), and bearings during towing and stop‑start work.

How it works

A belt‑driven shaft spins an impeller inside a precision housing. The impeller pushes coolant from the engine to the radiator and back, while a mechanical seal and high‑load bearings keep the system leak‑free and quiet. Correct flow keeps the thermostat and heater core operating properly.

If the pump fails ⚠️

Expect rising temperature, coolant drips at the pulley, bearing noise, steam, weak cabin heat, or heater cycling. Continued driving can blow the head gasket, warp the head, or seize the engine—expensive damage. Replace at first signs of leak or wobble.

Installer notes

Flush system, fit a new belt if worn, torque bolts evenly, use the specified coolant mix, and bleed air thoroughly to prevent hot spots.
