BMW Cooling System Parts & Accessories for BMW 5 Series E60 (2004-2010)

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.

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.

More than likely, you are going to replace the radiator in your vehicle at least once. The joints where the cores meet the end tanks tend to get weak and are the first place to spring a leak. Impacts to the fins themselves can cause holes to form. Corrosion and clogging from the inside can make cooling less than effective and compromise coolant flow. Replace your leaking unit with a factory replacement and get that jug of coolant out of your back seat. This is a factory original style radiator from Nissens and will fit perfectly into the stock location. Cooling will be identical to what your car came with originally. A great replacement with all the proper connections and in all of the proper locations.

This is the mounting bolt used for the water pump on all N55 engines as well as later (updated) N54 engines. These are sold per bolt and 3 are required for mounting the water pump.

This is a new and revised bolt design to match the updated water pump ( p/n 11517632426 ). BMW changed the design for the N55 and all subsequent replacement N54 pumps. The updated pump does not use a rubber isolator in the mounting flange. The previous water pump did have this rubber mount and required a longer bolt. The new bolts are also zinc-coated grade 8.8 steel instead of aluminum. That means the new bolts are re-usable instead of 1-time use like the old design.

Sold per bolt. 3 are usually required for the N54/N55 water pump.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

The coolant expansion tank in your vehicle gives additional fluid a place to go after expansion and contraction from temperature change. Because it is subjected to such drastic changes on a regular basis, it can often crack or break. You want to keep all the coolant in your vehicle in the cooling system. If your tank has experienced damage such as cracking, nipples breaking off, or mounting point damage, you will need to replace it.
