BMW 5 Series & X3 Electric Engine Water Pump – Part No. 11518635092 11517583836 – Restores Factory Cooling Performance & Prevents Overheating | Fits BMW 528i (F10, F11 2010–2011) & X3 xDrive28i (F25 2011–2012) with N52 3.0L Engine

Restore your BMW’s cooling performance and protect your engine from overheating with this OEM-style Electric Engine Water Pump—a direct replacement for Part No. 11518635092, which supersedes 11517583836.

BMW’s electric water pump is responsible for maintaining constant coolant circulation through the engine and cooling system so temperatures stay stable at idle, in traffic, and during spirited driving. When the pump starts to weaken or fails (often from repeated heat cycles, internal bearing wear, or electronic motor failure), it can quickly lead to coolant warnings, temperature spikes, reduced power/limp mode, or overheating—and overheating on these engines can turn into expensive repairs fast.

This replacement pump is manufactured to meet OEM fit and performance standards, delivering the proper coolant flow rate and reliability your cooling system depends on. Whether you’re replacing a failing pump after warning lights, or doing proactive maintenance for peace of mind, this unit restores factory cooling efficiency and helps keep your engine operating safely.

• “Engine Overheating” / coolant system warnings on the dash
• Intermittent overheating that comes and goes
