High-strength aluminum replacement adapters for the factory plastic water pump connectors on BMW S58 engines. Designed as a direct-fit solution to replace failure-prone OEM plastic parts. Prevents the need to replace the complete water pump assembly.
Item Code: LMA008
These aluminum water pump connectors are engineered as a direct replacement for the factory plastic adapters used on BMW S58 engines. The original connectors are known to crack or break over time, which can lead to coolant leaks. In many cases, BMW supplies only the complete water pump assembly as a replacement, significantly increasing repair costs.
This kit provides a more durable alternative. CNC-machined from high-quality aluminum, the adapters match OEM dimensions and fitment while offering improved strength and long-term reliability.
The adapters replace OEM reference 11518054857 (also listed as 8054857 or 11 51 8 054 857) and install in the same manner as the original parts. Each unit is supplied with pre-installed Viton O-rings to ensure proper sealing and resistance to heat and coolant exposure.
Installation is straightforward and follows standard replacement procedures. Light lubrication of the adapter before insertion into the rubber coolant hose is recommended to ease installation.
