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 stock plastic water pipe is prone to cracking after a long life of heating and cooling cycles. This could lead to coolant loss and an overheating engine. To prevent this, the URO Premium water pipe is constructed from aluminum that can withstand as many heating and cooling cycles that could ever be thrown at it and won't crack or become brittle over time.

2000-2005 E46 BMW M54 xi models
2000-2006 E53 BMW X5 M54 xi/xDrive models

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

This is a genuine BMW Motorsport part, designed specifically for BMW racing applications. We use this exact thermostat setup in our Championship-winning E46 330i race car. It is designed to be used on all M54 and M52TU double-VAN0S engines, as used in the 1999-2000 E46 323/328 and 2001-2005 E46 325/330. This 60 degree C (140 defrees F) thermostat comes complete with plastic thermostat housing. It does not use the plug and wiring for the stock DME so this should only be used with an aftermarket engine management system (Motec, Bosch, etc).

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.
