BMW Cooling System Parts & Accessories for BMW 6 Series F06 (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.

Red Line SuperCool Concentrate fortified with WaterWetter is a concentrated antifreeze/coolant designed to maximize the performance of your cooling system with superior protection against cavitation corrosion/erosion. Using SuperCool Concentrate diluted with distilled water protects the entire cooling system keeping new components like new for 5 years/150,000 miles and prevents further damage to older components. Red Line’s proprietary coolant additive formula enhances the fluid’s ability to transfer heat, reducing operating temperatures by up to 20*F and prolonging the life of the entire cooling system. Red Line's SuperCool is an OAT coolant that is a Nitrate and Silicate Free product with its own proprietary corrosion technology to offer superior protection for aluminum engines found in all European vehicles, performance vehicles, as well as other applications. SuperCool will not void the factory warranty either. It can be used to top off the existing coolant of any BMW and will not cause any ill-effects on the cooling system because it is silicate and nitrate free. It is still better to flush it out and switch completely to SuperCool to get all the full benefits of the product in performance and protection.

CSF has been at the forefront of pushing the performance limits of the S63 engine with its Twin Charge Air Coolers. Today, many M5, M6, and M8 models are exceeding 1000HP, but with greater power comes increased heat. As power levels rise, so do oil temperatures, with some owners experiencing temperatures surpassing 240°F (115°C) during intense track sessions. As these M cars continue to age and power thresholds are pushed further, factory cooling systems are struggling to keep up. To address this challenge, CSF partnered with Carbahn to develop a direct-fit solution for both platforms. Engineered to manage the extreme heat generated by Carbahn’s new S63 Stroker Kit, this oil cooler is designed for peak performance and reliability. But enhanced performance isn’t the only reason to upgrade. Many F1X and F9X owners have had to replace their oil coolers due to leaks and damage, primarily caused by their exposed mounting position—a problem worsened by lowered suspension setups. A stronger, more durable design was needed to resolve these issues. Whether your M5, M6, or M8 is a daily driver, weekend cruiser, or dedicated track machine, upgrading the oil cooler is a smart investment. Tuned S63s, especially those with upgraded turbos, produce significantly more heat, making efficient cooling even more critical. Excessive oil temperatures can quickly trigger limp mode and, in extreme cases, cause catastrophic engine failure. CSF’s new High-Performance Engine Oil Cooler isn’t just about optimizing performance—it’s a preventative upgrade that helps avoid costly repairs and extends your engine’s lifespan.

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.
