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.

A new power steering pulley is key to keeping your steering system smooth and reliable. Over time, pulleys can warp, crack, or wear, causing belt slippage, whining noises, or even pump failure. Installing a fresh pulley restores correct belt alignment, eliminates noise, and maintains consistent hydraulic pressure for precise, effortless steering. Why choose a new pulley? Smooth operation – Ensures proper belt tension for dependable pump performance. Noise reduction – Eliminates squealing, whining, or vibration from worn pulleys. System protection – Protects the pump and steering components from damage. Install a new pulley and keep your steering system running quietly, efficiently, and confidently.

This is an OEM Febi Upper Idler Pulley, also known as the roller pulley or deflection pulley. The upper and lower idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).
