High-quality water pump assembly 2722001801 for Mercedes-Benz -

Core Selling Points

Hot-sale cooling component for integrated one-stop purchasing

100% consistent with OEM dimensional parameters, direct bolt-on installation without modification

Applicable Vehicle & Engine Scope

• Matched Engine: M272 E35 3.5L V6 naturally aspirated hybrid powerplant
• Applicable Model: Mercedes-Benz W221 S400 Hybrid (2011–2013 factory production)
• Installation Position: Main circulating mechanical water pump for engine main cooling loop

Reinforced Durable Structural Design

1. High-precision die-cast aluminum pump body: High structural rigidity, outstanding heat dissipation performance, resistant to long-term high temperature and coolant erosion, hard to crack and deform
2. Optimized curved surface impeller: Stable liquid delivery flow, effectively improve the heat exchange efficiency of the whole cooling system
3. Double-layer fluororubber rotary shaft sealing structure: Excellent compression resilience, thoroughly block coolant seepage at the rotating shaft position
4. Wear-resistant integrated pulley body: Stable transmission fit with drive belt, no slipping or abnormal buzzing noise under long-time high-speed operation
5. Complete finished product equipped with matched installation gasket, ready for direct assembly

Core Functions & Engine Protection Value

1. Drive forced circulation of engine coolant, take away massive heat generated by engine combustion, and keep the engine working temperature within the safe rated range
2. Accelerate the warm-up progress of cold engine, ensure stable hot air supply inside the vehicle under low-temperature environment
3. Avoid serious engine failures such as cylinder head warpage and cylinder gasket breakdown caused by engine overheating
4. Stabilize the operating temperature of the hybrid power auxiliary system and protect the normal operation of the whole vehicle hybrid module

Common Fault Phenomena Solved

• Coolant seepage and obvious water stains near the water pump mounting position
• Water temperature rises sharply during driving, accompanied by dashboard high-temperature warning prompt
• Obvious abnormal vibration and noise at the front end of the engine
• Slow warm-up speed, cold wind or warm wind failure of the vehicle air conditioner heater
• Coolant liquid level drops frequently, requiring frequent manual replenishment of antifreeze liquid
