BMW Drive Belts & V-Belts for BMW F87 M2 N55 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.

Introducing our Turner Motorsport Crank Seal Guard – the essential shield for your BMW's engine integrity. Safeguarding the heart of your vehicle, this meticulously designed guard offers robust protection for the crank seal concealed behind the harmonic balancer.

Considered an indispensable maintenance component for your BMW, the Crank Seal Guard acts as a crucial defense against a potential and preventable catastrophe involving your accessory belt. Facing the reality of potential oil or coolant leaks in your engine, this guard becomes a reliable barrier, preventing these fluids from reaching the accessory belt. The consequence of a compromised belt includes walking, slipping, fraying, and rubber particles finding their way behind the harmonic balancer and into the crank seal – a scenario that can lead to severe engine failure.

Let's be honest, engine leaks are a common occurrence, and whether your engine is currently leaking or not, the Crank Seal Guard is a proactive measure against future threats. The wear and tear on the accessory belt due to oil and coolant exposure can result in slipping, tearing, or, worst-case scenario, belt snapping – posing a significant risk to your engine's well-being.

Prepare your car for the long haul and protect the vital components, It's not a matter of "if" but "when" your belt will become a problem, and our Crank Seal Guard is your proactive solution. Rigorously tested on N52/N54/N55 and S55 for 100% confirmed fitment, it stands as a reliable guardian for your engine's health. Invest in the protection your BMW deserves with the Turner Motorsport Crank Seal Guard.

Key benefits:

Protect crank seal from rogue accessory belts and their shredded debris
Optimized to fit N52, N54, N55, and S55 engines
Rigid design that fits within the space constraints between the engine block and harmonic balancer

BMW has a seemingly endless number of fans of the N54/N55/S55 engines, three straight-six turbo engines that are each capable of 750+ horsepower, but that doesn't mean they were without their faults! BMW's N54 had a notoriously rocky start with reliability due to multiple issues such as fuel injectors failing, turbos failing, serpentine belt failure, crank hubs coming loose, and more... BMW made multiple attempts to fix the issues plaguing the N54, but they could only do so much and the fixes rolled out seemed temporary at best. Following the N54, BMW released their updated N55 and S55 engines, giving many people hope that these engines would address the previous issues. Unfortunately, this was only some-what the case. Crank hubs and crank bolts continued to loosen over time and serpentine belts continued to shred themselves and get pulled into the oil pan through the front main seal. For all three engines, this meant a single failure could effectively turn your engine into an oversized paperweight. Luckily for us, the BMW community is full of skilled enthusiasts who have gladly taken up the task to offer solutions! The first headache to be addressed was the Crank Hub and Bolt. Using a simple plate that fits perfectly over your crank hub's hex-head bolt and mounts up against the damper, the crank bolt is effectively locked in place, preventing it from being able to back out until the plate is fully removed. Next up was the serpentine belt failures. It's not known what exactly causes the serpentine belt to split, but once it does, the pieces hanging off of the belt wrap around and behind the damper. This leads to the belt breaking up into smaller pieces and eventually getting pushed between the crank hub and rear main seal into the oil pan. These small pieces of debris get caught in and block the oil pickup, preventing oil flow and leading to engine failure. To prevent this, multiple aftermarket companies came up with their own versions of Crank Seal Plates. This plate is installed behind the front damper, blocking the opening that allows the serpentine belt to pass between the crank hub and seal, keeping debris out of your oil pan! Also included in this kit are the components to service your front Oil Cooler/Filter Housing gaskets, refresh your drive belt system, and install the aftermarket upgrades. Kit Features and Contents: Vargas Turbo Crank Bolt Capture Vargas Turbo Crank Seal Plate ECS Kevlar reinforced accessory belt OEM Belt Tensioner & Idler Pullies Liqui-Moly Longtime High Tech Engine Oil (5w-30) - 7 Liters OEM Hengst Oil Filter OEM Oil Filter/Cooler Housing Gaskets TMS Oil Change Sticker Genuine BMW Full-Strength Coolant - 1 Liter
