BMW Cooling System Parts & Accessories for BMW 6 Series F12 (2012+)

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.

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.

If your vehicle is struggling with cooling problems, the culprit could be the thermostat. Look out for signs like prolonged warm-up periods at highway speeds (indicative of a stuck-open thermostat) or consistent overheating (a sign of a stuck-closed thermostat). These issues can lead to performance issues and potential damage to crucial vehicle parts.

Key Features:

Ensured compatibility with your vehicle High-flow OE-style design ensures optimal engine cooling Factory housing dimensions for easy installation and secure hose connections Includes a temperature sensor where needed Constructed from durable alloy or composite material to resist warping or cracking, preventing coolant leaks

Turbocharger oil feed lines are often overlooked, but they play a critical role in turbo longevity. Replacing a worn or original feed line is an inexpensive safeguard against premature turbo failure. The oil feed line delivers a constant supply of clean, pressurized oil to the turbocharger bearings. Over time, exposure to extreme exhaust heat and repeated thermal cycling can cause oil to break down inside the line, leading to carbon buildup and restricted flow. Reduced oil supply quickly results in elevated bearing temperatures and accelerated wear. Installing a new turbo oil feed line restores proper oil delivery, helping maintain stable bearing temperatures and reliable lubrication. Many updated or upgraded feed lines feature improved materials, refined routing, or additional heat shielding to better withstand the high-temperature environment surrounding the turbocharger. Benefits of replacement: Helps prevent oil starvation caused by internal restriction Protects turbocharger bearings from heat-related wear Extends overall turbocharger service life Recommended preventative maintenance during turbo replacement or high-mileage service Especially important for increased boost or upgraded turbo applications In short, replacing the turbo oil feed line is a smart preventative maintenance step that supports long-term reliability and consistent performance.

This is the coolant temperature sensor used in many BMW models from the late-1990s to the mid-2010s. The engine computer relies on the coolant temp to set the fuel mapping for the engine. As the car warms up the computer changes the fuel mixture. If your car is running a bit rich (too much fuel) it could be because this sensor is failing and not sending the correct info to the computer. This sensor is located in a variety of places depending on the engine. But it's one of those easy replacement items 'while you're in there' when doing a water pump or thermostat replacement. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.
