BMW Cooling System Parts & Accessories for BMW X Series E70 (2007-2013)

Clear BMW chassis

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 coolant expansion tank in your vehicle provides extra space for fluid expansion and contraction due to temperature changes. Because it regularly experiences these fluctuations, it can become prone to cracks or breaks over time. To ensure that all coolant remains within the system, it's important to replace the tank if it has been damaged, such as with cracks, broken nipples, or damaged mounting points.

Made of reinforced rubber, these hoses are prone to issues such as splitting at hose clamps, swelling, cracking, or even breaking, which can leave you stranded. It's important to replace them at the first sign of wear to prevent coolant loss and ensure your engine stays properly cooled.
