BMW Cooling System Parts & Accessories for BMW F80 M3 S55 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.

BMW F8X M3 M4 CTS Performance Heat Exchanger is designed to provide superior cooling for the BMW S55 engine platform, addressing the inefficiencies of the factory-installed heat exchanger. The factory front-mounted heat exchanger often struggles to keep tuned S55 engines cool, but this high-performance solution from Turner Motorsport is engineered to enhance cooling efficiency. Featuring a double-pass core, this heat exchanger is both larger and more effective than the factory unit while fitting perfectly into the stock location. Precision CNC-machined mounting points and hose connections ensure a seamless installation without the need for any cutting or trimming. Additionally, the integrated vent simplifies air bleeding from the cooling system after installation.

  • Enhanced cooling: Provides superior cooling for tuned S55 engines, overcoming the limitations of the factory heat exchanger.
  • Double-pass core design: Larger and more efficient than the stock unit for improved heat dissipation.
  • Seamless installation: CNC machined mounting points and hose connections ensure easy installation without modifications.
  • Integrated vent: Facilitates easy air bleeding from the cooling system post-installation.
  • Vehicle compatibility: Specifically designed for BMW F8X M3 and M4 models with the S55 engine.

Upgrade to the BMW F8X M3 M4 CTS Performance Heat Exchanger from Turner Motorsport for optimal cooling and enhanced performance.

The 3.0 Liter S55B30 turbo engine for BMW M2/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 cores of the WAGNERTUNING high performance water coolers increase the radiator volume of the OEM water coolers by 89% for front mounted and 94% for side mounted. 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 front mounted radiator: 590 mm x 308 mm x 25 mm / 23,2Inch x 12,1Inch x 1,0Inch V = 4,5 Liter A = 1817 cm² / 280,7Inch² Dimensions WT front mounted radiator: 568 mm x 468,4 mm x 32 mm / 22,4Inch x 18,4Inch x 1,26Inch V = 8,5 Liter (+89%) A = 2660,5 cm² / 412,2Inch² (+46,4%) Kit comes with: 1x front mounted radiator (low-temperature circuit) 1x installation instruction

The Precision Raceworks Billet Coolant Cap Set is a functional and stunningly stylish way to add a nice touch to any engine bay! These caps come in three color options, so there is always a color that will work for you! Black with Billet Silver, Black with Blue, and the Stealth series (all black). Many people don't realize it, but the OEM caps have a pressure release valve built into them. Oftentimes, aftermarket companies don't know this either or just don't care. But our team cares about proper function just as much as we care about the appearance of every product we design. For pressure relief, our caps incorporate the OEM internals, so you get all the functionality of the original caps, ensuring a safe and reliable system in place. These caps offer superior style and performance-grade components that guarantee a reliable fit every time. Durable billet aluminum construction provides long-lasting protection and dependability that will upgrade your engine bay for years to come. PLEASE NOTE: These do require assembly and swapping the pressure relief valves from your old caps to your new billet caps.

Water Wetter is a unique wetting agent for cooling systems which reduces coolant temperatures by as much as 30*F. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Or it can be added to new or used antifreeze to improve the heat transfer of ethylene and propylene glycol systems. Designed for modern aluminum, cast iron, copper, brass, and bronze systems.

We have been using RedLine Oil in our street cars and race cars for years. Hands-down, it is the Number One brand of high performance lubricant for BMWs.
