This comprehensive kit includes both belts, belt tensioners, upper and lower deflection pulleys, and the adjusting pulley. Select from all Genuine BMW parts or a combination of OEM/OE BMW parts. Staying on top of your belt maintenance is the smart move. Cracked or worn belts are a recipe for a headache or worse. The main drive belt runs critical components - the alternator, water pump, and power steering pump. The pulleys contain bearings that may be worn when it comes time to replace the belts. You can check the pulleys by relieving tension on the belt and feeling each pulley for play or grinding. The tensioner also sees similar wear. If your pulleys are new or don't need replacement, you can pick up the belts on their own.

Eliminate your squeaking accessory belt pulley and cracked drive belt with this upgraded accessory belt service kit! This kit includes ECS Kevlar Reinforced Drive Belts, tensioner assemblies, and new tensioner pulleys. ECS Tuning's Red Kevlar Accessory Belts are both an aesthetic improvement and a performance alternative to a traditional belt. Kevlar-reinforced belts experience less elongation over time minimizing the amount of belt adjustment needed as well as offering a higher shock and impact resistance compared to OEM-style belts. Refreshing the rollers and/or tensioners simultaneously is a great way to ensure all vital components of your drive belt system are functioning optimally for years to come!

This is a Genuine BMW 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).
