BMW Cooling System Parts & Accessories for BMW 6 Series E63 (2004-2010)

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.

Has your BMW's with the N62 V8 engine developed a coolant leak at the front of the engine from the timing cover weep hole? If so the it is likely that the coolant transfer pipe seal, located below the intake manifold has developed a leak. Normally, replacing the seal on this pipe would require almost 40 hours of labor and involve removing the entire engine from the car, then removing the cylinder heads, and timing covers. With this new collapsible pipe this repair can be accomplished in under 10 hours! This solution will save you or your mechanic from a bunch of headaches and get your V8 back on the road leak free!

With more than 100 years in the industry, Elring is one of the oldest names in the European autoparts segment. Delivering OE-quality you can rest assured the job will be done right the first time.
