Installation Guide
Tools Required:
Torx T40/T45, coolant drain pan, BMW ISTA/D software, torque wrench (20–25 Nm).
Steps:
Safety Precautions:
Let the engine cool completely.
Drain coolant via the radiator petcock into a pan.
Remove Accessories:
Detach the serpentine belt (use BMW tensioner tool).
Remove the thermostat housing (8mm bolts).
Replace Pump:
Unbolt the pump (6x T45 Torx bolts).
Clean the mating surface with a gasket scraper.
Install the new pump with OEM gasket (torque to 22 Nm).
Reassemble & Refill:
Refill with BMW-approved G48 coolant (50% concentrate).
Bleed air via the bleed screw on the thermostat.
Coding (If Required):
Use ISTA/D to reset adaptation values for the cooling system.
Where to Buy & Red Flags
Trusted Suppliers:
BMW dealerships, FCP Euro, ECS Tuning, RealOEM.
Avoid:
Pumps lacking BMW’s engraved part number (11517643067).
Sellers claiming “universal fit” for B58/N55 engines.
Maintenance Tips
Replace coolant every 60,000 miles (G48 degrades over time).
Inspect the pump during oil changes for leaks/noises.
Use distilled water for coolant mixtures to prevent scaling.
FAQ
Q: Does 11517643067 fit a 2023 BMW X5 with B58 engine?
A: Yes – Compatible with all B58-powered X5/X6 models.
Q: Can a failing pump cause turbocharger damage?
A: Yes – Overheating warps turbo bearings and oil seals.
Q: Why does my new pump require coding?
A: B58/N55 engines need thermostat adaptation resets for optimal flow.
Q: Are aftermarket pumps safe for BMW’s warranty?
A: No – Non-OEM parts may void the engine/drivetrain warranty.
Q: How to test the pump without removing it?
A: Check for play in the pulley (side-to-side movement >2mm = failure).
Conclusion
The BMW Mechanical Water Pump 11517643067 is critical for maintaining engine longevity, turbocharger health, and cabin comfort. Genuine OEM pumps ensure precise coolant flow, leak-free operation, and compatibility with BMW’s advanced thermal management systems. Aftermarket alternatives risk overheating, premature bearing failure, and costly repairs. Trust factory-engineered components to protect your BMW’s performance and value.
