Water Pump with Metal Impeller

The Graf water pump (part number 11 51 0 393 336) is an OEM-quality replacement engineered to meet the performance and fitment requirements of BMW's M62TU V8 engines. This water pump is distinguished by its metal impeller, a significant upgrade over the weaker stock plastic composite design, offering greater longevity and resistance to failure, which is a common issue on these vehicles. This water pump is specifically designed for the following BMW models: E39 540i (from 09/98 production), E38 740i and 740iL, and the E53 X5 4.4i and 4.6is. It directly supersedes BMW part numbers 11511713266. The product includes a gasket, and it is recommended to also replace the thermostat o-ring (part # 11 51 1 705 408) and water pipe o-rings (parts # 11 53 1 710 048 and # 11 53 1 710 055) during installation. Graf is an original equipment manufacturer supplier for BMW water pumps, ensuring that this part meets all original design, fitment, and performance standards. It is also TUV approved. This makes the Graf water pump a cost-effective alternative to genuine BMW parts, offering virtually identical quality at a reduced price. The part comes with a two-year warranty.
