One-stop purchasing water pump assembly 1151 7586 925 for BMW 5 Series

Core Selling Points

Ideal for mixed one-stop bulk sourcing with stable recurring orders

Electronic water pumps are high-failure-rate core overhaul parts for N52 engine vehicles. Original pumps suffer brushless motor burnout, mechanical seal aging, impeller wear and control board failure after long-term high-temperature operation. Faulty pumps trigger engine overheating, limp mode, slow cabin heating, coolant leakage and cooling system fault codes. Professional BMW service shops and cross-border wholesalers often combine this pump with full cooling system spare parts for one-stop orders to cut procurement cycles and logistics costs, with steady year-round reorders and high profit margins for dealers.

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

Manufactured strictly following BMW original Pierburg OEM standards: aluminum housing contour, threaded coolant inlet/outlet, mounting hole spacing, PWM electrical plug pin definition and internal flow channel all fully match genuine 11517586925. No pipeline cutting, wiring refitting or extra ECU coding required after replacement; matched installation bolts are optional for one-stop matching, greatly shortening engine disassembly and coolant bleeding labor hours.

Full Compatible Vehicle Range (Focus on BMW 5 Series)

• BMW 5 Series E60/E61 (2004–2010): 523i, 525i, 528i, 530i (N52B25 / N52B30)
• Cross-platform interchangeable models: E90/E92 3 Series, E83 X3, E70 X5, E85/E89 Z4 with N52 engines

Reinforced heavy-duty high-temperature durable structure

1. Die-cast aluminum pump housing, excellent thermal conductivity, anti-deformation under sustained engine bay high heat
2. Upgraded wear-resistant closed PPS impeller, rated flow ≥7000L/H, stable coolant circulation, not easy to jam by tiny impurities
3. Double-layer high-temperature fluorine rubber mechanical seal, permanent anti-coolant leakage, compatible with all ethylene glycol antifreeze
4. IP67 fully sealed brushless motor + built-in PWM intelligent control board, real-time variable speed adjustment by DME, no intermittent signal failure
5. Standard threaded metal pipe joints, tight sealing without air blockage; complete positioning mounting holes for quick assembly

Intelligent variable-speed cooling to fully protect N52 engine

Different from traditional belt mechanical pumps, this electric pump automatically adjusts operating speed based on engine load, water temperature and vehicle working conditions. Accelerate cold engine warm-up to reduce fuel consumption; enhance large-flow heat dissipation under high-speed full-load driving to avoid overheating; continue residual heat circulation after flameout to eliminate heat soak damage, effectively extend engine service life.

Fully resolve typical water pump failure malfunctions

Perfectly fixes common N52 cooling system faults:

• Sudden engine temperature surge and dashboard overheating warning
• Vehicle enters limp mode with obvious power drop
• No hot air or slow heating inside cabin in cold weather
• Abnormal continuous buzzing noise from engine compartment after ignition
• Coolant seepage and water stains at pump mounting flange
• ECU stores cooling pump malfunction fault codes

Rigorous multi-stage factory testing & sufficient mixed spot inventory

Each water pump undergoes dynamic flow test, water tightness leakage test, high-low temperature cycle aging test, motor durability test and ECU signal matching inspection before delivery, compliant with IATF 16949 automotive quality standards. Mass ready stock supports mixed one-stop bulk procurement with N52 engine thermostats, auxiliary water pumps, cooling hoses, radiator and overhaul gaskets. Custom neutral packaging and private label OEM services are available for cross-border wholesale customized demands.
