Product Specification

High-quality Auxiliary Coolant Water Pump 64119230237 for BMW 5 Series

This premium electronic auxiliary water pump with OE number 64 11 9230 237 is an essential heating and cooling system component for BMW 5 Series chassis models, a regular stocked maintenance part favored by BMW professional repair shops and cross-border auto parts wholesalers.

Core Selling Points

High-frequency heating system consumable with stable repeat bulk orders

Auxiliary water pumps are easily damaged wearable parts for BMW 5 Series. Original pumps suffer internal motor aging, impeller wear, shaft seal leakage and circuit failure after long-term frequent startup. Defective pumps lead to slow cabin heating in winter, insufficient auxiliary cooling for turbo, abnormal engine temperature at idle, coolant leakage and abnormal buzzing noise. Specialized BMW service garages and global spare parts distributors place recurring bulk orders all year round, bringing steady sales volume and favorable profit margins for dealers.

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

Manufactured strictly in accordance with BMW original mold specifications: pump housing outline, mounting hole spacing, coolant inlet/outlet pipe size and wiring plug pin definition fully match genuine OEM standards. No pipeline cutting or wiring refitting required during replacement, directly installed on the original vehicle cooling pipeline to greatly cut maintenance labor hours.

Compatible Vehicle Range

BMW 5 Series F10/F11 520i, 525i, 528i, 530i, 535i with N20/N55 engines; also applicable to F07 5 Series GT, F01/F02 7 Series, X3 F25, X5 E70 with matching cooling circuit.

Reinforced durable high-temperature resistant structure

1. Corrosion-resistant reinforced plastic pump body, compatible with all types of antifreeze, withstand long-term high temperature inside engine bay
2. Smooth wear-resistant closed impeller, stable coolant circulation, not easy to jam by tiny impurities
3. Double-layer high-temperature mechanical sealing ring, effectively block coolant seepage and dripping
4. Fully sealed waterproof motor module, isolate dust and water vapor to avoid short circuit and motor burnout
5. Original standard plug connector, stable electrical signal transmission without triggering heating system fault codes

Stable auxiliary coolant circulation to improve heating & heat dissipation

Independently drive the small circulation loop of coolant during vehicle idle or low-speed driving. Speed up cold engine warm-up, deliver lasting hot air for the cabin heater, assist heat dissipation of turbocharger, and prevent abnormal temperature rise in traffic jams, greatly improving riding comfort and protecting engine components.

Fully resolve typical auxiliary water pump failure faults

Perfectly fixes common cooling & heating system malfunctions:

• Slow or no hot air output inside the car in cold weather
• Engine temperature rises abnormally when idling for a long time
• Coolant leakage and water stains at pump mounting position
• Continuous abnormal buzzing noise after ignition
• ECU stores auxiliary water pump related fault codes

Rigorous multi-stage factory testing & sufficient spot stock

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