Water Pump Pulleys for BMW X Series E83 (2004-2010)

Clear BMW chassis

Before BMW switched to electronic water pumps, mechanical water pumps were belt driven. If you're replacing your BMW's water pump, you should also replace the water pump pulley. We recommend lightweight water pump pulleys if they are available for your BMW.

Most of the pulleys on your BMW engine are plastic, which become brittle and frail over time and from engine bay heat. A failed pulley could leave you stranded which is why it is vital to inspect the pulleys during routine maintenance. This is an aluminum version of the stock water pump pulley used on the M50/M52/M52TU/M54 engine in the E36, E46, Z3, Z4, and other models. It uses the same hardware and the original belt as the stock plastic pulley. But the aluminum will last much longer.
