BMW Water Pumps for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

The water pump is a known failure point on most BMWs, new and old. Older model BMWs come from the factory with a mechanical fan that features a plastic impeller. If your BMW still has a water pump with a plastic impeller, you should upgrade to one with a metal impeller to avoid future failure. New BMWs utilize an electric water pump that cost BMW millions of dollars to design - when it is working it is great, unfortunately these fail so regularly that we recommend replacing your electric water pump every 60,000 miles to avoid stranding yourself on the side of the road. We have hand selected the best OE suppliers for replacement water pumps so you don't have to pay the high cost of Genuine BMW. However, if you're someone who only puts Genuine BMW parts on your car, we understand - that's why we have those available for you as well.

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 5-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.

When it comes time to replace the water pump, be sure to replace all the O-Rings associated with it to ensure that your car stays leak free. If you are experiencing leaking issues, be sure to inspect these rings, as they might have worn down. This is used on the return pipe to the thermostat housing
