BMW Maintenance & Tune-Up Parts for BMW 5 Series E39 (1996-2003)

This is an OEM INA tensioner pulley, also known as the adjusting pulley and lower pulley. This pulley is mounted on the belt tensioner near the center of the belt assembly. The upper and lower pulleys are known to be the primary sources for 'belt squealing'. This 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).

This pulley is mounted along with the hydraulic belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-M54 family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines). This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time. If you have a mechanical belt tensioner, the pulley can only be replaced with a new tensioner.

Every 60-80,000 miles, we recommend replacing your spark plugs to ensure your ignition system is running optimally. Over time carbon can build up around the head of the spark plug and decrease spark strength and effectiveness, leading to weaker fuel mixture detonation, misfires, and potential check engine lights. To prevent this, have put together our High-Performance Ignition Service Kits. These kits include new Bav Auto High-Performance Ignition Coils, new spark plugs, dielectric grease, and a BMW spark plug service label to keep track of when your spark plugs were replaced.

Bav Auto's Ignition coils feature core windings that have been modified to increase firepower and promote a faster, more efficient burn. This gives your BMW/MINI increased torque in the lower range of RPM and more horsepower in the upper range. Exact improvements depend on the current condition of your engine, but you'll definitely feel the difference. They'll also improve your fuel economy.

From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. This kit includes Redline D4 ATF, the transmission filter, gasket and bolts.

Kit Includes:

• Automatic transmission filter with associated hardware
• Oil pan gasket
• Drain plug with sealing washer
• Fill plug with sealing washer

Hydraulic Belt Tensioner for E36, E46, E39 6-cyl models. This is the oil-filled tensioner that keeps the main drive belt in the proper tension. Over time the piston seals inside allow fluid to leak out. The tensioner becomes frozen or inoperable. Replacement is the best corrective action to take. This can be done during any belt or pulley service or anytime the fan is off the engine.

Liqui Moly is an official sponsor of Turner Motorsport. We work closely with Liqui Moly to ensure your BMW is receiving optimal lubrication! 

Liqui Moly GmbH develops and tests all engine oils, additives, and car care products in-house, ensuring all Liqui Moly products extend the life of your engine via optimal lubrication. With more than 50 years of experience and reviews across the world from magazines and race teams, Liqui Moly proves time and time again why they are one of the most innovative lead forces of performance automotive chemicals in the world. Turner Motorsport trusts Liqui Moly to keep all of our race cars - including the M6 - running smooth from the first hotlap to the last.

Turner Motorsport Recommends three Liqui Moly oil options for your BMW:

Leichtlauf High Tech full synthetic engine oil is designed to provide the highest amount of engine protection as well as fuel savings and reduced oil consumption - most BMWs like to drink oil, Leichtlauf should make yours less thirsty. Using proprietary blends of base oils and the latest additive technology, this oil will ensure smooth running gasoline and diesel engines in both high and low temperatures. Other amazing benefits include: optimum oil pressure at all speeds, rapid oil delivery at low oil temperatures, high shear and aging stability, turbo, multi-valve, and supercharger compatibility, and long service life.

Synthoil Premium engine oil is designed to provide great engine wear protection as well as fuel savings and reduced oil consumption. Using proprietary blends of base oils and the latest additive technology, this full synthetic oil will ensure smooth running gasoline and diesel engines in both high and low temperatures.

New generation Molygen engine oil allows you to easily identify oil leaks with the included UV flashlight - BMWs are notorious for oil leaks, and this allows you to work towards solving this problem. Additionally, Molygen is a fully synthetic oil designed to provide the highest amount of engine protection as well as fuel savings and reduced oil consumption possible. 

Choose the level of Liqui Moly Oil Service your BMW deserves: 

• Liqui Moly Bronze service involves switching to Liqui Moly oil without the introduction of additives.
• Liqui Moly Silver service includes a Pro-Line Engine Flush to remove sludge and carbon buildup from the oil circulation system.
• Liqui Moly Gold service includes Silver service and Jectron Fuel Injection System Cleaner. This cleans your injectors and maintains your fuel system to improves engine performance and efficiency.
• Liqui Moly Platinum service includes Gold service and Cera Tec Oil Additive. This prevents wear and reduces friction to improve engine performance and efficiency.

Below you can add new drain plug and crush washer, along with your choice of oil filter.

This kit also features many Popular Service Tools that make your life easier when working on your BMW:

• Turner Motorsport Magnetic Fender Cover
• Schwaben 6.5L Fluid Extractor
• Schwaben 14mm/17mm Service Wrench
• Schwaben Professional BMW/MINI Scan Tool

Have you ever been bent over your engine bay for a few hours and noticed that your belt scratched your fender? We've got you covered with the Turner Motorsport Magnetic Fender Cover. We also offer a myriad of Schwaben tools. Schwaben's Professional Scan Tool vastly simplifies diagnosing your BMW. This scan tool offers OE-level diagnostics for over 25 years of models, also allowing you to access common service features like resetting your oil service light, installing a new battery, throttle body adjustment, DPF regeneration, and more. The Schwaben Fluid extractor allows you displace 6.5L of fluid without making a mess of your workspace. Lastly, we've found that the 14mm/17mm service wrench allows you to service most of your vehicle with just one tool - one of the biggest hangups with working on a vehicle is losing your tools. Save yourself time looking for multiple different tools across your garage by owning one that does it all.

Don't up with the maintenance on your car is the smart thing to do. For one thing, it prevents costly repairs in the future. For another, your car performs better, making aftermarket upgrades more worthwhile. And a well-maintained car with complete service records can add substantially to a car's resale value. Our service packages for your M5 will ensure you get many more miles from your BMW muscle car.

The M5 is a special car in BMW's line-up and it takes special attention to maintain its lofty output. Looking after the M5's various needs and problem areas will reward you with a better M ownership experience and make your car stand out from less cared-for cars if/when it's time to sell. In addition to the normal maintenance items listed below, you may also want to check or replace the following:
+ fuel pump (especially if the car is hard to start or stumbles in the RPM range)
+ front (pre-cat) oxygen sensors
+ check valve cover gaskets, intake plenum seals, vacuum lines, and hoses for leaks
+ service or replace crankcase vent valve/oil separator system
+ VAN0S solenoid rebuild or replacement

Just like the rest of your vehicle's major systems, the cooling system must also be addressed periodically to ensure proper cooling and component reliability. Plastic and rubber components become brittle and prone to splitting or cracking after long periods of heating and cooling cycles, especially in colder climates! The coolant itself can degrade or become contaminated, leading to potential corrosion or freezing issues. Finally, thermostats and sensors can fail completely, preventing proper cooling and/or coolant temperature readings to become inaccurate.

To make sure you are not left stranded on the side of the road with an overheated engine, we have put together this Basic Cooling System Service kit. This kit contains all of the most-likely-to-fail components, giving you peace of mind knowing your engine will continue to run cool for another 60,000+ miles.

See kit contents below for all included components.

Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained.

Often an oversight in maintenance, ignition components are also susceptible to wear and tear. Spark Plugs can accumulate carbon, reducing the spark intensity and it's ability to properly ignite the air/fuel mixture, leading to misfires and generally declining performance. Other ignition components, such as coils, boots, wires, caps, and rotors, can also wear out over time due to factors like heat and contamination, preventing the current from reaching the spark plug.

To start over fresh with all new components, we now offer these Ignition Service Kits. Each kit comes with brand new OE quality components, replacing any potential fault points in your ignition system for peak performance!
