BMW Maintenance & Tune-Up Parts for BMW 3 Series E46 (1999-2005)

As the E46 M3 gets on in years and mileage, the cooling system will be one of the areas that needs the most attention. We have packaged all of the major cooling components into one overhaul kit:

• radiator
• water pump
• thermostat
• radiator hoses and clamps
• gaskets and o-rings

We have found that the E46 M3 can develop inconvenient cooling issues, even on daily driven street cars. While the infamous radiator and water pump failures of the E36 are a thing of the past, the E46 M3 still has its own complications. The best approach to avoid bigger problems is preventative maintenance. We recommend replacing the water pump before 80,000 miles and the radiator before 100,000 miles. By addressing these problem areas before a failure, you will save yourself a larger repair bill in the future.

In addition to the standard cooling package items above, there are several other cooling-related components that may make sense to do at the same time:

• Original BMW coolant
• fan clutch
• main serpentine belt and A/C belt
• Turner Power Pulley Kit (because now is the perfect time!)

This cooling overhaul package fits:
2001-2006 E46 BMW M3
 

If you plan to drive your BMW aggressively on the track, it is important that you upgrade your cooling system to avoid overheating. To ensure your BMW keeps cool on the track, we have built out our new High Performance Cooling System Upgrade kits. Featured in this kit is everything you will need to redo your cooling system from top to bottom with OEM components, with select stock components swapped out for the high performance alternative! This kit includes a high performance Mishimoto Radiator, for significantly better cooling than the stock radiator and full aluminum construction that won't crack from long term heat cycling, a performance Mishimoto 70*C thermostat, for lower temperature operation and increased cooling of the engine, and a Stewart High Performance Water Pump, for dramatically increased coolant flow at all RPMs. 

Additional items included in this kit:

• OEM Replacement Coolant Hoses
• OEM Expansion Tank, Cap, and Level Sensor
• OEM Belts, Tensioners, and Pulleys
• OEM Auxiliary Fan Switch
• Genuine BMW Hardware for Easy Installation
• ECS Tuning Aluminum Water Pump Pulley - For increased reliability over the stock composite pulley

The hoses and oil separator can crack or become faulty, leading to vacuum leaks or oil leaks. This is caused by the stress the plastic components are exposed to during heating and cooling cycles, especially if the vehicle is not brought up to operating temperature during driving in cold weather climates.

This kit includes the needed hoses, oil separator, and hardware.

Fits the following BMWs:

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code but not always a check engine light. A misfire code may be related to an ignition coil but could be from other things as well. Sometimes a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.

This is the current replacement for some BMW 6 and 8-cylinder engines built in the late 2000s and after. BMW has made numerous changes to ignition coil part numbers in recent years but has approved this part number to work in the vehicles listed below. It's listed as a replacement coil for N20, N55, and S55 engines. In March 2015 BMW approved it for N51/N52 engines. This part number replaces the previous BMW part number 12137594937 for the cars listed below.

Sold per coil. Includes boot and connector.

Liqui Moly Molygen New Generation fully synthetic engine oil is carefully engineered, starting with a high quality synthetic base. What separates Molygen from other engine oils is the molecular friction modifier for reduced friction and wear. Because of this, Molygen glows fluorescent green under UV light, allowing you to easily find any leaks!

The fluorescent green chemical friction modifier smooths out hard metal surfaces, reducing overall engine wear and heat due to friction. Tests have shown to reduce the friction coefficient by 15%!? MolyGen oil is also a great choice for modern forced induction engines which produce much more heat. BMWs are notorious for leaking oil. Make chasing your leak easier with Liqui Moly Molygen New Generation engine oil. (Once you find it, give us a call - we can help you stop that leak, too!)
