Clear BMW chassis

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.

Gates FleetRunner Micro-V Belts are a top choice, featuring patented EPDM construction with a distinctive green overcord. Designed for heavy-duty drives, these belts offer superior flexibility, stability, and extended lifespan. While originally intended for the heavy-duty diesel market, enthusiasts worldwide rely on Gates FleetRunner belts for their unmatched durability and performance.

Accessory drive belts keep everything turning off of the crank pulley. Generator, fans, water pumps and AC compressors all 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. Designed for long life, this belt will keep everything turning great and all of your accessories working properly. With a worn belt, accessories aren't working at maximum efficiency. Do not wait for this belt to break to replace. Replace it as part of your next maintenance plans.
