Please ensure your correct model is selected

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 accessory drive belts are essential for keeping various components running smoothly off the crank pulley. These belts power critical systems like the generator, fans, water pumps, and AC compressors, ensuring optimal functionality. When your drive belt shows signs of aging such as cracking, glazing, or squeaking, it's time for a replacement.

You can easily spot wear and tear on the belts. Look for glazing on the underside, which indicates reduced effectiveness. Cracks on the back of the belt can result from "dry rot" caused by engine heat or age. Squealing noises are also common with worn belts, indicating slippage on pulleys. In either case, it's crucial to install a new belt for your vehicle's optimal performance.

Designed for heavy-duty drives, these belts offer superior flexibility, stability, and extended lifespan.
