BMW Drive Belts & V-Belts for BMW X Series E70 (2007-2013)

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.

A new power steering pulley is key to keeping your steering system smooth and reliable. Over time, pulleys can warp, crack, or wear, causing belt slippage, whining noises, or even pump failure. Installing a fresh pulley restores correct belt alignment, eliminates noise, and maintains consistent hydraulic pressure for precise, effortless steering. Why choose a new pulley? Smooth operation – Ensures proper belt tension for dependable pump performance. Noise reduction – Eliminates squealing, whining, or vibration from worn pulleys. System protection – Protects the pump and steering components from damage. Install a new pulley and keep your steering system running quietly, efficiently, and confidently.

The vibration damper in the E70 X5 35d is a common failure item and can fail at as low as 60 thousand miles leaving you stranded. This kit includes everything needed to replace your vibration damper and service your drive belt system! Vibration Dampers (also called Harmonic Dampers or Harmonic Balancers) absorb and remove unwanted vibrations due to torsional twisting of the crankshaft. During cylinder combustions, the crank quickly flexes ever so slightly, resulting in resonance vibrations. These vibrations could lead to damage of the crankshaft or crank bearings over time if not accounted for. The vibration damper helps to eliminate these vibrations, thereby extending the life of your engine's mechanical components and preventing damage. If your vibration damper has failed, you will likely notice excess engine vibrations or shaking that will gradually get worse, especially around certain RPMs where the vibration resonance is most pronounced. This kit includes all of the components necessary to replace your damper with an OEM damper from Corteco, including belts, pulleys, hardware, and more. Also included in this kit is a brand-new line of specialty tools from Schwaben designed specifically for this replacement! You will get a Crankshaft Pulley Turner Tool, Stretch Belt Remover/Installer, T50 Alternator Wrench, and a 15/16" Pass-Through Socket, all included to make swapping out your old damper a quick and easy process! Standard tools you might need but are not included: 8mm Drill Bit (to use as flywheel locking pin) 32mm Fan Clutch Wrench - You may want a second 32mm to hold the coupler in place 24mm Box Wrench - For releasing tensioner Torque Wrench - To torque new crankshaft bolts Breaker Bar - to drive the crankshaft bolts further

Is your BMW making a chirping or grinding noise at idle? The culprit is frequently a failing alternator decoupler pulley. Unlike a traditional solid pulley, this Overrunning Alternator Pulley (OAP) allows the alternator rotor to "freewheel" when engine speeds drop suddenly. This specialized function protects your BMW drive belt and belt tensioner from excessive snap-back, vibration, and "belt slap."

Prevent Catastrophic Engine Failure

Over time, the internal clutch mechanism can seize or slip, leading to accelerated wear or total serpentine belt failure. On BMW engines, a snapped belt can be ingested through the front main seal, causing catastrophic engine damage. Replacing this pulley is a cost-effective preventative maintenance step that restores smoothness to your accessory drive without the high cost of a complete alternator replacement.

Features & Benefits:

Lowers the load on the drive belt, tensioner, and AC compressor.
Stops "belt slap" and rhythmic chirping noises during deceleration and idle.
Direct Replacement with high-quality construction ensures perfect fitment and long-term durability.
Essential Maintenance for N52 engines

If your accessory belt idler pulley shows signs of excessive wear—such as wobbling, grinding, or squealing from a failing bearing—it should be replaced before it leads to belt failure. When replacing your idler pulley, it's a good time to inspect other belt drive components like the tensioner and belt for wear. Turner Motorsports offers a full selection of belts, tensioners, pulleys, and related hardware to keep your BMW’s belt drive system running smoothly.
