BMW Drive Belts & V-Belts for BMW F97 X3 M S58 3.0L

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.

The OE crank bolts are grade 10 torque-to-yield bolts, designed for only a single use. For vehicles making stock power, the stock bolts are more than enough. Unfortunately, vehicles making more power than stock have experienced issues with the stock damper bolts coming loose and breaking, leading to engine and crank damage. 5150 AutoSport worked with ARP to create this ARP Harmonic Damper Bolt Set to address this issue. These upgraded bolts are stronger than the factory bolts and are designed to provide even repeatable torque load, preventing them from breaking and allowing them to be re-torqued as needed.
