BMW Drive Belts & V-Belts for BMW X Series E83 (2004-2010)

Clear BMW chassis

Your BMW's drive belts are wear items, and will degrade and crack over time. Don't wait until you have a belt failure... don't get stranded! Replacing your BMW's belts, such as the alternator belt, power steering belt, air conditioning AC belt, or serpentine belt is a low cost insurance policy to preventing a break down -- or worse, engine damage. We recommend checking your belts every 10,000 miles. If your belts have excessive cracks, dry rot, missing teeth and/or grooves, are cause noise, it's time for new ones.

While also inspecting your serpentine belts, also check for wear or resistance in the pulleys. The tensioner pulley and deflection pulley are the primary sources for belt squealing. The rubber-isolated pulleys can also break apart, leading to total belt failure. We sell the tensioner and deflection pulleys for the M50 engine family used in the E34, E36, E39, E46, X5, Z3, and Z4.

Eliminate your squeaking accessory belt pulley and cracked drive belt with this upgraded accessory belt service kit! This kit includes the ECS Kevlar Reinforced Drive Belt, tensioner assembly, and idler pulley. 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!

Every time the cylinders fire, torque is transferred into the crankshaft. The crankshaft deflects under this torque, which sets up vibrations when the torque is released. At certain engine speeds the torque imparted by the cylinders are in sync with the vibrations in the crankshaft, which results in a phenomenon called resonance This resonance causes stress beyond what the crankshaft can withstand, resulting in crankshaft failure. The accessory pulley acts as a balancer and prevents these vibrations from destroying your crankshaft.
