BMW Drive Belts & V-Belts for BMW E34 M5 S38 3.5L

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.

AC compressors rely on this belt to keep everything working properly. If your drive belt is getting old, cracking, glazing, or squeaking, replace it. It's easy to see when the belts are beginning to wear. Visually, the belt will begin to glaze on the underside, making it far less effective. Cracks can appear on the back of the belt from “dry rot” caused by exposure to engine heat or age. Squealing is common on worn belts which basically means that the belt is slipping on pulleys. In either case, your vehicle needs a new belt.
