This pulley is mounted along with the hydraulic belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-M54 family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines). This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time. If you have a mechanical belt tensioner, the pulley can only be replaced with a new tensioner.

This high-quality replacement from Bremmen Parts is designed for exact fitment on your BMW. Whether you're looking to complete much-needed preventative maintenance, or replacing a failed roller, choose this component from Bremmen Parts for a lasting repair.

This item is 70mm Diameter. Please check the diameter before ordering.

If your VANOS system is leaking, replace the gasket to restore the tight seal. An oil leak here will cause a significant amount of oil to leak down the front of the engine and if isn't fixed, could potentially lead to issues with the VANOS system itself.

Elring has supplied many automotive names for years with the gaskets that seal your car's components from day 1 so you can rest assured that these components will last for a long time to come!

Having your oil pressure light come on can mean very serious problems. Or it could just be this switch that fails several times over a car's lifespan. By no means should you ignore the warning light but replacing this sensor could be the actual culprit. The other problem with this switch is that oil can leak past its seal. With the oil under a lot of pressure at this point, the oil loss can be a serious concern. It's a simple replacement when doing most oil change work.

This Oil Pressure Switch fits the following BMWs:

Turn your oil drain plug into an effective metal particle filter! This drain plug fits virtually all BMWs, and has a SUPER strong magnet built into it's tip, trapping iron and steel contaminants and safely removing them from the circulation.

This is a must for ALL BMWs, and simply installs in place of your existing drain plug. With every oil change you perform on your BMW, you'll be able to inspect for metal shavings and debris. Many times, if something is going wrong on your BMW's engine, the drain plug can give you an early warning. Our championship race team uses this info all the time (Ever find a piece of a valve spring in your oil? We have!) Be sure to get one now, and make the swap next oil change!

This magentic drain plug most BMWs (except pre-1980's). It includes a new/fresh copper washer.

This hose runs from the oil separator to the intake manifold and is designed to allow the recirculation of built-up oil vapors.

Due to its proximity to engine heat, this hose tends to get brittle and break as it ages. This can lead to oil leaks, vacuum leaks, misfires, and more.

If your crankcase ventilation hose is brittle or leaking, replace it with this unit from URO Parts.

This is an OEM INA 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).
