Highly popular water pump 2722 0004 01 for Mercedes-Benz -

This widely favored auxiliary electric water pump adopts OEM part number 272 200 04 01, manufactured with 1:1 original vehicle mold for Mercedes-Benz vehicles equipped with M272 2.5L/3.0L/3.5L and M273 4.7L/5.5L V6/V8 naturally aspirated engines.
It is an independent auxiliary circulation pump for vehicle heating and auxiliary cooling circuit. When the engine idles, stops or runs at low load, this pump continuously drives antifreeze circulation to maintain stable heating output inside the cabin and assist engine heat dissipation.
Original pumps will face motor burnout, rotor jamming and shaft seal leakage after long-term high-temperature circulation, resulting in weak warm air, abnormal running noise and cooling system fault codes. This aftermarket replacement pump delivers stable and lasting performance, keeping consistent repeat orders in global auto repair markets.
