BMW Cooling System Parts & Accessories for BMW G87 M2 S58 3.0L

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.

This performance heat exchanger from CTS features a number of upgrades over the stock intercooler, offering better reliability and cooling performance. The first major upgrade is the heat exchanger's full alumnimum constructions. The factory heat exchange is partially constructed from plastic, which is prone to damage and cracks as the plastic becomes brittle over time. Full aluminum construction results in a stronger intercooler, which will last the lifetime of your BMW. The second major upgrade is a redesign of the coolant flow path and fin layout. This redesign allows for higher cooling efficiency, resulting in greater heat dissipation and reduced coolant temperatures.

The 3.0L I6 bi-turbo engine of BMW M3/M4 models is equipped with an indirect charge-air cooling circuit. So the cooling of the charged air is not realized by the ambient air as cooling medium (as usual), but made with its own cooling water circuit. A reduction of the temperature of the cooling water is directly equated with an improved cooling performance of the charged air. This is exactly where the advantages of the WAGNERTUNING upgrade water cooler comes into play. The new developed competition racing core of the WAGNERTUNING high-performance water coolers increases the radiator volume of the OEM water coolers by a total of 60 %. The calculated ratio between the inner and outer cooling surface generates a maximum heat transfer and allows at the same time enough air flow for the surrounding components (for example the engine water cooler) for its own heat exchange. The water coolers are equipped with a heat-conductive anti-corrosion coating to ensure a lasting cooling effect. The plug & play installation of the system is simple and easy to perform (an installation instruction is included as well). Dimensions OEM radiator: 505 mm x 605 mm x 30 mm V = 9.16 Liter A = 3055 cm² Wagner Dimensions 505 mm x 605 mm x 48 mm V = 14.67 Liter A = 3055 cm²

When it comes to BMW's we all know the weak point is commonly in the cooling system, many models proving hard to bleed the air pockets out after the refresh. The coolant refill tool solves this problem, ensuring that you get an air pocket free fill. The entire task is as simple as draining the system like normal, reinstalling the drain plugs and hooking the tool up to your refill location. The reason this tool works so well is due to the venturi valve, it converts air pressure from the compressor to vacuum inside the cooling system, then with a twist of a valve sucks coolant right into the system using the vacuum pressure.
