BMW Cooling System Parts & Accessories for BMW E46 M3 S54 (1999-2005)

Clear BMW chassis

Please ensure your correct model is selected

The cooling system is arguably the weakest point in numerous BMWs. If you drive an aging BMW or plan on taking your car to the track like we do, we recommend beefing up your cooling system before going to the track. Generally, the main components in your cooling system that are prone to failure include the following: expansion tank, factory hoses, water pump, thermostat, fan (especially if your vehicle comes factory with a clutch fan), and radiator. Factory BMW expansion tanks are plastic and prone to either breaking off at connection points or combusting. As factory rubber hoses age they either crack or break over time - we offer silicone cooling hose upgrades for most applications to avoid future failures. If you have an older vehicle, your water pump likely comes from the factory with a plastic impeller - we offer upgraded water pumps with metal impellers that are far more reliable. Newer model BMWs utilize electric water pumps - BMW spent millions of dollars engineering these water pumps, but they fail so often that we recommend replacing at 60,000 mile service intervals to avoid being stranded on the side of the road. In terms of thermostats, we offer various upgraded thermostats for racing applications. If your BMW utilizes a clutch fan from the factory, we have several options available in terms of universal electric fans - we recommend replacing these to avoid sending brittle plastic fan blades through your hood. For radiators, we recommend swapping out your radiator for one that does not use plastic connection points like your factory radiator.

The E46 M3 does not suffer from the cooling nightmares of the previous E36 models. The original water pump uses a composite impeller, not plastic or metal, so the BMW pump will typically last 85,000+ miles before the bearings show signs of wear (the composite impeller is not the reason for preventative maintenance - it's the bearings). We prefer the OE BMW pump to the aftermarket brands because it uses the composite impeller, it has a proven reliability record, and the pricing represents a solid value upgrade. The pump is located on the front of the engine with the fan attached to it. The complexity of the S54 engine means the water pump has multiple gaskets and seals that should also be replaced. And if the thermostat has not been changed then this is the best time for a new one as well.

Optional Gaskets
The S54 water pump has multiple gaskets and O-rings that should be replaced at the same time. The water pump does not come from BMW with a profile gasket anyway and all of the hoses and thermostat housing have their own seals. We don't recommend re-using the original gaskets so we have an add-on kit that will have you covered during your water pump replacement -
1 x 11531318402, thermostat housing gasket to water pump housing
1 x 11537830709, coolant return pipe on thermostat housing
1 x 11517831099, water pump profile gasket
2 x 11537830712, coolant hose rubber O-rings

Composite vs Metal
BMW designed this water pump to use a composite impeller. It is much stronger than the plastic pieces that were so problematic in the mid-90s. The aftermarket solution to the plastic issues was to use a metal impeller. This solved the impeller issues but created some others. The metal impeller is heavier than composite or plastic and that led to quicker bearing failure on the E36 pump (sometimes within a year). The possibility exists that the same premature bearing failure can happen on the E46 M3 metal impeller pumps as well. The heavier weight also has the drawback of using more horsepower since it requires more effort to move the heavier piece. The composite materials solve all of these issues - light weight, strong, long lasting, and relatively inexpensive. They also come with a two-year warranty (most aftermarket pumps are one year). Original BMW water pumps for the E36 (and most other modern BMWs) now use a composite impeller so any issues with factory pumps are long gone. Original BMW water pumps for the E46 M3 are known to last over 100,000 miles and the composite is still in excellent condition (failure is usually typical leaks from worn bearings). For preventative maintenance we recommend a replacement around 85,000 miles. Alternate part numbers: 11517838118, 11517838159.

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.

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

BMW has been designing notoriously failure-prone cooling systems since the late 1980s. The coolant capacity in most BMW engines is not sufficient to accommodate any driving or overheating near red zone temperatures. After the gauge reaches this critical area, it is common for thousands of dollars in damage to occur. Stop the problems before they arise. If your vehicle has 80,000 miles or more, replace all of these components to ensure that your vehicle stays healthy. To keep everything in top order, continue to replace these components at 80,000 mile intervals.

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. Ideal for the SE46 racing series, the AAF E46 6-speed Transmission Crossmember is a heavy-duty and worthwhile upgrade. The OEM thin cast aluminum cross member has been known to fail in multiple different ways. When using stiff engine and transmission mounts, the cross member can crack out and break around these mounting points. The cross member can also break from the high amounts of load transferred through the drive train. While chassis flex from hard cornering is being applied through the engine and transmission from the front cross member, this load is sent from the transmission back into the chassis at the transmission cross member. This is simply too much stress for the OEM cross member to hold up to under the extreme punishment of road racing. The AAF E46 Transmission Cross Member is completely constructed of 1/4' thick heavy-duty aluminum plate. It is designed specifically to cope with hours of endurance racing.

This is the coolant temperature sensor used in many BMW models from the late-1990s to the mid-2010s. The engine computer relies on the coolant temp to set the fuel mapping for the engine. As the car warms up the computer changes the fuel mixture. If your car is running a bit rich (too much fuel) it could be because this sensor is failing and not sending the correct info to the computer. This sensor is located in a variety of places depending on the engine. But it's one of those easy replacement items 'while you're in there' when doing a water pump or thermostat replacement. 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.
