Bmw E46 320d Fan Belt Diagram

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.

Most of the pulleys on your BMW engine are plastic, which become brittle and frail over time and from engine bay heat. A failed pulley could leave you stranded which is why it is vital to inspect the pulleys during routine maintenance. This is an aluminum version of the stock water pump pulley used on the M50/M52/M52TU/M54 engine in the E36, E46, Z3, Z4, and other models. It's uses the same hardware and the original belt as the stock plastic pulley. But the aluminum will last much longer.

Fit the following BMWs:

Underdrive Power Pulleys work to 'free up' horsepower. Any accessory that spins from the main drive belt is using up power. That's power that could otherwise be used to move the car. By giving some of that power back to the engine, you can make the car faster! It's like FREE HORSEPOWER !

Underdrive pulleys for your BMW will slow down engine-mounted accessories - the water pump, power steering pump, and alternator*. These systems contribute to 'parasitic losses' - power lost from what the engine could produce if it did not have these systems. Since less energy is used to move them, that power is transferred back to the engine and used to propel the car. Our pulleys give a 5-10% reduction in rotation, releasing up to 11hp on most BMW six-cylinder engines. There's also a small but noticeable improvement in throttle response too! We have done extensive testing and development work, both on and off the track, to ensure that the accessory systems function as they should. On our Racing pulley kits we actually underdrive certain components more so we feel our Street pulleys are an ideal compromise between power/torque gains, reliability, and system performance. Our pulley kits have been on the market for over ten years, and used in all of our own cars, with zero component failures related to their use.

Our pulleys are made from T-6061 aluminum and finished in a durable black hard anodize that is very resistant to wear, chemical exposure, and heat. We designed our pulleys to look similar to the factory parts but also to be stronger and, in most cases, slightly lighter too. For example, a Turner alternator pulley is less than half the weight of the stock steel pulley! With our hardcoat aluminum you will never have to worry about a serious failure of a stock plastic pulley. A 'stealth' approach to aesthetics was our goal and we let the results speak for the pulley design. Installation is straight forward and easy with simple hand tools. Removal of the fan is required for access to the front of the engine. Total install time for a 3-piece pulley set should be around 1.5 hours. A new longer belt is included and we also recommend replacing the separate A/C belt, belt tensioners, and the guide and deflection pulleys at the same time.

* Alternator Pulley Options
Bosch or Valeo? BMW built your car with either a Bosch or Valeo brand alternator. Unfortunately, the pulley is not the same for both brands. The brand is usually printed on the black plastic cover of the alternator but may be facing the frame rail or the ground. If you know which brand you have, select your option below and we'll send you the correct alternator pulley for your BMW. Don't know which you have? NO PROBLEM! We can send you both. The 2nd pulley costs $40 but you will receive a refund once we get the un-used pulley back (return shipping not included).

Stereo Systems. We offer our kits in two different ways: the full Power Pulley Kit with all 3 pulleys or a 2 pulley kit if you do not wish to underdrive your alternator (for large stereo systems or other battery-draining modifications). Our kits have been tested for compatability with the factory premium stereo systems (Harmon Kardon, etc). But any major alterations or upgrades from the factory system will work best with our 2 pulley kit and no underdriving of the alternator. For all stock stereo systems the 3 pulley set is recommended because the Turner alternator pulley will help make more power and is also much lighter than the stock pulley.

If you are breaking crankshafts and oil pumps, the cause may be a mystery to you as it has been to many of our customers. We know that controlling the harmonic resonance of the BMW 6 is highly important as RPMs rise, but the ideal configuration of the inline-6 motor makes even experienced engine builders overlook some fundamental principals of engine harmonics that can be destructive. ATI Performance Products has partnered with VAC Motorsports to develop new dampers for BMW 2.5L, 2.8L, 3.0L and 3.2L straight-6 engines found in the E36 and E46 M3 as well as newer Z3s and Z4s. These dampers eliminate crankshaft harmonic vibration, which allows the engine to produce more horsepower and torque, while also reducing internal engine wear at the same time. Broken oil pumps and timing chains will be a thing of the past! When used with a VAC accessory pulley, these dampers are a direct replacement over the OEM balancer. They have a 7" outer diameter and include OEM style timing alignment tabs. BMW enthusiasts should know that all ATI Super Dampers exceed SFI 18.1 Safety Certification and are approved for competition. The advantages of the ATI SuperDamper include eliminating vibration issues with inline 6 engines equipped with lightweight clutch and flywheel assemblies, reduced bearing, engine accessories, oil pump wear, and compatibility with underdrive pulleys. Kit includes: Damper Lightweight VAC Billet Crankshaft Pulley Mounting and Installation Hardware Trigger Ring for OBD1 systems Note: Will NOT work with S50B30 & S50B32 Euro Engines, For Street/Track cars with Air Conditioning, the Additional A/C Pulley Option is REQUIRED as the OE A/C pulley is not compatible. The additional mounting and installation hardware is also included. Made in the USA

TMS E46 M3 Racing Pulley is designed to achieve three goals: gain horsepower, reduce alternator and power steering pump wear, and lower power steering fluid temperatures. Due to the constant high revolutions of the S54 power steering pump when on the track, we designed our racing power steering pulley to slow down the pump. This lowers fluid temperatures, resulting in less wear to the pump. This kit also includes a large alternator pulley, which also reduces wear. Kit uses our street water pump "under drive" pulley. All of these working together produce a significant gain of over 15 horsepower. The pulley has been track tested on our Grand Am Cup M3's and dyno-tested. This is strictly for race/track cars only, due to the size of the alternator pulley the proper voltage cannot be maintained at low RPM. Note: We sell pulleys separately in case you have special needs. Simply give us a call, or drop us an email.

This kit covers many of the common wear items that should be changed any time the serpentine belt is being replaced. As these cars gain years and mileage the belt tensioners will also need to be replaced along with the actual belts. It won't do any good to replace the belt if the tensioners are worn. This kit will save you time and money over buying these pieces individually. This kit includes an updated hydraulic alternator tensioner for added reliability and longevity.

This is the stock water pump pulley that mounts between the engine fan and the water pump. We have seen these plastic or composite pulleys crack around the mounting bolt holes. If left un-noticed the whole pulley can fall apart which will immediately disable the car and possibly leave you stranded. It can also break while performing other work around it such as removing the fan, replacing the water pump, or even just replacing the belt. Replacing this pulley while doing the water pump can be a good preventative measure.

This item fits the following BMWs:
1999-2005 E46 BMW 323i 323ci 325i 325ci 325xi 328i 328ci 330i 330ci 330xi

Don't let power steering failure ruin your weekend and cost you a win! In the Grand-Am Cup series, TMS has found that the power steering pump on the M3 S54 is prone to wear potentially costing you a win or even a finish. The TMS Racing Power Steering Pulley is designed to achieve three goals: gain horsepower, reduce power steering pump wear, and lower power steering fluid temperatures. The pulley has been track tested on our Grand Am Cup M3's and dyno-tested. This pulley is strictly for race/track cars only. We suggest installing with the TMSRacing E46 M3 Alternator pulley P/N: TEN 46 22 RM3

Turner Motorsport Race Alternator Pulley For E46/Z3 M54 Bosch Alternator

Part of the process of building a proper race car is to delete and simplify portions of the wiring harness. This not only saves weight and reduces complexity, but it also allows you to run a smaller, lighter racing battery. So why is your alternator still charging at the original rate?!? This M50/M52/S52 racing alternator pulley underdrives the alternator more than our standard Power Pulley, freeing up horsepower and reducing alternator wear. This pulley is over 80% larger than the original stock pulley. With less electrical load, you don't need the original alternator output anymore. You can drive the alternator less and return that "lost" horsepower back to the engine. This part is an upgrade to the alternator pulley already included in our Power Pulley kit and was developed and race-proven on our E46 Touring Cars.

Because this pulley is so much larger than the original (80%), special care will need to be taken so that it does not interfere wtih other components on the engine - power steering lines, oil cooler lines, coolant hoses, etc. The upper idler pulley is no longer needed with the racing pulley and will be removed. A new belt is required (add one from the options below).

For Bosch alternators only.

The remainder of theTurner Power Pulley Kit is required (water pump and power steering pump pulleys).

This is a Genuine BMW Upper Idler Pulley, also known as the roller pulley or deflection pulley. The upper and lower idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).

Continental is the OEM supplier for the stock serpentine accessory belt on your M52TU or M54 engine. They are also the OEM for many other components on your entire car. This extensive kit covers many of the common wear items that should be changed any time the serpentine belt is being replaced. As these cars gain years and mileage the belt tensioners will also need to be replaced along with the actual belts. It won't do any good to replace the belt if the tensioners are worn. This kit will save you time and money over buying these pieces individually and you get OEM-quality over any 3rd party aftermarket brands.

Included in the accessory belt and tensioner kit is:

  • main drive belt, 11281706545
  • A/C belt, 11281437450
  • mechanical belt tensioner with pulley, 11281427252
  • A/C belt tensioner with pulley, 11287512758
  • deflection pulley, 11281748130
  • mounting bolts

This kit fits cars with the mechanical belt tensioner only. Generally this is all cars up to 2002 model year but you may want to double check your car and match the picture to the tensioner on your engine. The hydraulic tensioner has a miniature shock absorber on the belt tensioner. You can also tell early from late by the A/C belt. BMW changed the spec from a 5-rib belt up to 2002 to a 4-rib belt from 2003 onwards. This kit does not fit any M56 SULEV engines.

This item fits the following BMWs:

Rogue Engineering has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This allows for perfect operation in daily driven vehicles without a hiccup or stutter. However, when the demand for power is requested, the power pulley kit allows for the freed power to become apparent.  The term "power" pulley is a bit of a misnomer. Underdrive pulleys actuallyfree up power by reducing the drag caused by the accessories.  These pulleys are based off a calculated percentage from factory dimensions, so that particular component speeds aresafely reduced without affecting their true purpose.

Rogue Engineering Power Pullies are CNC machined from 6061-T6, heat treated aluminum and specially coated with a MIL-A-8625 Type III hard coat anodize finish. This kind of anodizing is not to be confused with a Type II cosmetic anodize finish (typical colors such as red, blue, silver, green, etc.). The hard coat anodize finish actually builds a small surface layer on top of the aluminum, preventing wear.

This part fits the following BMW engines:
S54

This part fits the following chassis:
E46, Z3, Z4
