BMW Heavy-Duty Aluminum Water Pump Pulley for E46 E39 E38 X3 E83 X5 E53 | M52 M54 Engines | Part No. 11511436590

Prevent Catastrophic Engine Failure – Upgrade Your BMW’s Cooling System

Ditch the weak factory plastic water pump pulley and upgrade to our heavy-duty billet aluminum version, precision-engineered for BMW M52 and M54 engines. The OEM pulley is known to crack over time, especially under high RPMs or engine bay heat, which can throw your serpentine belt and cause critical coolant circulation failure. Our CNC-machined aluminum pulley is built to last—offering peace of mind and improved reliability for your cooling system.

• CNC-Machined Billet Aluminum – Built from aircraft-grade material for superior durability
• Prevents Pulley Failure & Belt Damage – Stops cracks from forming sharp edges that shred or misalign the serpentine belt
• Improves Cooling Reliability – Keeps your belt-driven water pump operating smoothly
• OEM+ Fitment – Direct bolt-on replacement with factory-style dimensions

FITMENT: BMW models with M52 / M54 inline-6 engines, including: E36, E46, E39, Z3, X5 E53.
