IRONTREE Water Pump Kit for BMW L6 Engines — 252-284 Direct-Fit with Gasket, OE-Style Durability

IRONTREE's 252-284 water pump kit is a complete replacement pump and gasket assembly designed to restore coolant circulation in BMW 2.0L–3.2L inline-6 engines across many 1, 3, 5, 6, 7, X, Z and M models.

This kit contains a precision-engineered water pump with gasket, manufactured to meet OE-style specifications and bench-tested for leakage and function. It is intended as a direct-fit replacement for a wide range of BMW L6 engines—covering common years and variants for reliable fitment and straightforward installation. The pump upgrades key internal components like bearings, impellers and mechanical seals to improve durability and maintain proper coolant flow under typical driving conditions.

Will this water pump fit my BMW model and engine?

• Covers common L6 engines from early 1990s through mid-2010s, including turbocharged L6 in later models
• Refer to your VIN or OEM part cross-reference to ensure exact match

How does this pump improve reliability compared with a worn unit?

The kit replaces worn bearings, impeller and seals that commonly cause leaks, noise or reduced coolant flow. IRONTREE manufactures to tight tolerances and tests each assembly for leakage and function, reducing the chance of premature failure when installed correctly. Improved internals are intended to meet or exceed OE form, fit and function.

• Upgraded bearing life and mechanical seal for longer service intervals
• Impeller designed to restore designed coolant circulation and pressure
• Bench-tested for leak-free performance before shipment

What’s included and how simple is the installation?

The package contains one water pump with its matching gasket, so you get all the sealing components required for a correct replacement. The pump is a direct replacement part made to align with factory mounting points and coolant passages, which simplifies swap-out for technicians or experienced DIYers. Use proper torque values and fresh coolant when completing the replacement.

• Single complete water pump assembly plus gasket included in the kit
• Direct-replacement design to match OEM mounting and plumbing
