Product Specification

High Sales Auxiliary Water Pump A2118350264 for Mercedes-Benz E-Class W211

This hot-selling auxiliary coolant pump with OE number A211 835 0264 is a key cooling system electronic component for Mercedes-Benz E-Class W211 chassis, a regular stocking part favored by luxury car repair shops and cross-border auto parts wholesalers with sustained repeat orders.

Core Selling Points

Hot-selling cooling consumable with stable year-round bulk reorders

Auxiliary water pumps are high-frequency replacement parts for W211 routine maintenance. Original electric pumps suffer internal motor burnout, impeller wear, seal aging and circuit failure after long service. Malfunctions lead to slow warm air in winter, overheating risk at idle, weak heating for seat/auxiliary heater and dashboard temperature alarms. Professional Mercedes repair garages and global spare parts distributors place recurring bulk orders all year round, bringing steady sales volume and good profit margins for dealers.

100% OE precise fit, plug-and-play direct installation without modification

Manufactured strictly following Mercedes original mold standards: overall outline, mounting hole layout, coolant inlet/outlet pipe size and electrical plug pin definition fully match genuine OEM specs. No pipeline cutting or wiring modification required during replacement, easy to mount on the vehicle cooling pipeline to greatly cut maintenance labor hours.

Compatible Vehicle Range

Mercedes-Benz E-Class W211 (E200, E240, E280, E300, E350 petrol & partial diesel models); also applicable to CLS C219 with shared cooling system layout.

Reinforced durable electric pump structure

1. Wear-resistant high-speed plastic impeller, stable coolant circulation without blockage
2. Sealed waterproof motor housing, resist engine compartment moisture and dust to avoid short circuit
3. High-temperature resistant internal mechanical seal, prevent coolant leakage under long-term operation
4. Standard original plug connector, stable signal conduction without fault codes
5. Anti-corrosion pump housing, compatible with all types of antifreeze coolant

Stable auxiliary circulation to balance engine temperature & heating effect

Drives independent coolant small circulation loop when the vehicle is stationary or at idle. Speed up warm-up in cold weather, ensure stable warm air output inside the cabin, assist main radiator to dissipate residual heat and avoid abnormal engine temperature rise during traffic jams.

Fully resolve typical auxiliary water pump failure faults

Perfectly fixes common cooling system issues:

• No hot air or slow heating in winter
• Engine temperature rises abnormally when idling for a long time
• Coolant leakage at auxiliary pump joint
• Abnormal buzzing noise from the pump after ignition
• Cooling system related fault codes stored in ECU

Rigorous multi-stage factory testing & sufficient spot stock

Every auxiliary water pump passes circulation flow test, air tightness leakage test, high-low temperature aging test and electrical conduction inspection before delivery, compliant with TS16949 automotive quality standards. Mass ready stock supports mixed one-stop bulk procurement with thermostats, water pumps, cooling hoses and other engine cooling parts. Custom neutral packaging and private label OEM services are available for cross-border wholesale buyers.
