URO Premium BMW Cooling System Parts & Accessories

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 N73/74 V12 engine water pipes could often fail at lower mileages, leaking a ton of coolant and prevent coolant flow to the rear of the engine block. If not addressed immediately, this could lead to engine overheating and complete failure. Unfortunately, these pipes are also very expensive and time consuming to replace when using the stock water pipe due to the amount of labor time needed for tear down and installation. This URO Premium collapsible water pipe kit is the perfect replacement to cut down on installation time by removing the need to tear down the front end of the engine before installing this part, potentially saving you thousands of dollars at a shop or a ton of hours in your own garage. 

Fits the following BMW engines:
N73, N74

Your factory thermostat to cylinder head coolant hose comes with a plastic connector, which is often referred to as a "Mickey Mouse" connector, that is known to fail at the mounting tabs. This can allow the coolant hose to come free from the cylinder head and cause major coolant loss. Replace your hose and connector with this URO Premium hose to eliminate this point of failure and prevent coolant loss and overheating.

Having an operational bleeder screw for your coolant system assures that when service is performed, all air pockets are removed. Having air pockets in your coolant system prevents your system from functioning properly. Your heat may not work as well and there is the potential for engine overheating if the air pocket is trapped behind the thermostat. Be sure that all of the air is bled out of your system with a new bleeder screw.

Subject to the ravages of heat cycling during each driving cycle - rubber hoses are more susceptible to wear and fatigue than aluminum piping. BMW utilized a single part number for their aluminum pipe and hose combination - making this part typically over $100 to replace. Rein to the rescue! By supplying just the rubber component, repairs can be made quickly and cost effectively (and without the waste of scraping a perfectly good aluminum pipe!) Includes both hose clamps and rubber hose.
