BMW Cooling System Parts & Accessories for BMW 3 Series F30 (2012+)

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.

The N20/n26 engined cars already suffer from reduced cooling area because of the factory intercooler, tight space under the hood, and of course heat from the turbo(s). BMW addressed these challenges a number of ways, including a dynamic, 'smart' electric water pump with increased output compared to normally aspirated models. The cooling demands mean additional stress on the major cooling components, especially the water pump and thermostat.

If your vehicle is experiencing cooling issues, chances are the thermostat is the cause. Common symptoms include prolonged warm-up at highway speeds from the thermostat being stuck open, or consistent overheating issues from the thermostat being stuck in the closed position. Either condition can result in poor performance, and potential damage to vital components in your vehicle.

Kit includes

  • Wahler Thermostat

BMWs are well-known for their problematic cooling systems, which often lead to irreversible engine damage and hefty repair bills. The coolant expansion tank—a crucial component that holds hot engine coolant under high pressure—is a common cause of cooling system issues. Unfortunately, BMW chose to manufacture the factory F3X expansion tank out of plastic. After years of exposure to high coolant temperatures, ambient engine bay heat, and chemical-rich antifreeze, the plastic degrades, eventually weakening enough to fail catastrophically.

With this issue in mind, our team of BMW enthusiasts engineered the ultimate cooling system upgrade for the N55-equipped F3X: a heavy-duty expansion tank built to last! Crafted from durable 5052 TIG-welded aluminum, this tank resists high temperatures and pressures without degrading over time. Unlike the fragile OEM plastic tank, Turner’s design eliminates the risk of cracking, leaking, or failure. Upgrade to our Heavy Duty Aluminum Expansion Tank Kit and say goodbye to expansion tank issues for good!

To guarantee exact fitment, the upgraded tank was designed using advanced 3D CAD modeling. All bungs, nipples, and fittings are precision-machined to ensure a secure seal with factory hose ends. Unlike other aftermarket options, this tank maintains the factory coolant capacity and includes our laser-cut logo plate at the top, providing an accurate fill level. Internal baffles are incorporated to prevent fluid cavitation, eliminating air pockets in the cooling system and avoiding false coolant level warnings during spirited driving.

Engineered for high-performance builds and daily drivers alike, this expansion tank boasts a premium wrinkle black powder coat finish for a clean "OEM+" aesthetic. This tough coating not only enhances appearance but also protects against corrosion for long-term durability. The kit includes a silicone overflow hose, a high-quality level sensor, and an OE expansion tank cap, offering a complete cooling system upgrade. Avoid the risks of the factory expansion tank—upgrade your BMW today and drive with confidence!

Over time, factory rubber hoses break down and eventually fail as a result of consistent exposure to chemical-rich antifreeze and hot engine bay temperatures. While all coolant hoses are prone to failure, the expansion tank hose is especially susceptible to failure. To fix this issue, ECS has created the ultimate performance hose upgrade! Crafted from heavy-duty, fiber-reinforced silicone, this ECS Exact-Fit Silicone Expansion Tank Hose withstands higher temperatures and greater pressure than the factory rubber alternative. Engineered to resist electrochemical degradation, it’s tested for continuous operation at 250°F and over 45 psi, ensuring improved reliability, enhanced flow, and reduced turbulence. To further improve upon the factory hose design, ECS engineers developed precision-machined billet aluminum "Quick Connect" hose ends. Unlike the OEM plastic counterparts, these robust components resist heat-induced failure, ensuring long-term durability and reliability. Replaces OEM Part Numbers: 17128570061, 17128507235. Installation is straightforward: begin by removing the factory overflow hose and retaining clips. Transfer the OEM metal clips from the factory connector to the new billet fittings, then press the fittings onto the expansion tank and upper coolant hose. The included silicone hose is routed through the OEM path and securely clamped onto the billet fittings. After installation, the fittings can stay in place, only the silicone needs to be removed for future maintenance. Key Benefits: Direct OEM Fitment – Retains factory hose routing while eliminating the weaknesses of rubber construction. High-Temperature Resistance – Silicone material withstands extreme heat and chemicals for long-term durability. 2-Ply, Fiber-Reinforced Fluorosilicone Construction – Provides superior resistance to glycol-based coolant and other harsh fluids. Upgraded Billet Aluminum Quick-Connect Ends – CNC-machined from 6061-T6 aluminum with integrated O-rings, ensuring a secure, leak-free connection that won’t degrade over time. Easy Installation – Includes stainless steel clamps for a hassle-free, bolt-on upgrade.

**** DOES NOT INCLUDE HARDWARE ****** Hardware - ES4772301 The N55 engine is no stranger to oil cooling problems, that�s why we recommend installing the MSL Oil Thermostat. The standard oil thermostat will reach around 120 degrees Celsius with a normal driving style. The MSL Oil Thermostat will open at a lower temperature than the standard oil thermostat (at 85 degrees Celsius) and will keep the temperature stable between 95 and 105 degrees Celsius. Installing the MSL thermostat ensures a cooler oil temperature which will result in more stable performance, but above all this improves the reliability of the engine. It is recommended to install the thermostat, especially for cars that are tuned. The Thermostat is plug-and-play and made out of a solid block of high-grade aluminum at our own facility. It is equipped with a real thermostat, not an always open solution. The oil will still reach the operating temperature at the same time as a stock thermostat Features Include: 20�C/68F Lower Than Stock Rock Solid Housing - CNC machined housing. Real Thermostat - Equipped with a real thermostat, not an always open solution. For use in hot and cold climates Quick Installation - Takes only 30 minutes to install.

The perfect upgrade for your connection between your thermostat and cylinder head. Designed using durable silicone and billet aluminum to greatly outlast the OE rubber and plastic combination. Some of the weakest points of the cooling systems in BMW's can come down to the OE plastic fittings breaking down from the constant changes in temperature, softening these plastic components. When this happens, even simply moving the hose slightly could cause the fitting to crack, causing the coolant to leak all over. The ECS design silicone hose with billet aluminum adapter retains OE fitment with superior strength to not only handle the performance, but also stand up to the wear and tear of a daily driver. Features: Manufactured from billet 6061-T6 and type III anodized for exceptional durability and corrosion resistance. Much stronger part than OEM plastic Will not become brittle and fatigue over time due to thermal cycling. This will prevent the part from breaking during removal and re-installation. Constructed of 4-Ply reinforced silicone for improved durability over the failure-prone OE rubber hose. Flourosilicone lined internal layer for exceptional chemical resistance. Silicone offers reduced thermal conductivity as well as improved resistance to ozone and UV degradation for improved performance and durability. Follows OEM form for perfect fitment. Utilizes OEM O-ring 11537545278 to ensure a proper seal. Replaces Genuine BMW Part Number: 11537598234

Engine running a little hot or is the temp gauge not telling you anything? The thermostat might be the likely problem. Many cooling issues start with the thermostat. This is electronically controlled by the engine computer based on the cooling demands of the engine. And cooling components are working harder than ever. Engine performance is also dependant on temperature - as temperatures rise and pass a certain threshold the engine computer will begin reducing power. Stay on top of your cooling maintenance by replacing critical components preventatively.

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.

The perfect upgrade for your connection between your thermostat and cylinder head. Designed using durable silicone and billet aluminum to greatly outlast the OE rubber and plastic combination. Some of the weakest points of the cooling systems in BMW's can come down to the OE plastic fittings breaking down from the constant changes in temperature, softening these plastic components. When this happens, even simply moving the hose slightly could cause the fitting to crack, causing the coolant to leak all over. The ECS design silicone hose with billet aluminum adapter retains OE fitment with superior strength to not only handle the performance, but also stand up to the wear and tear of a daily driver. Features: Manufactured from billet 6061-T6 and type III anodized for exceptional durability and corrosion resistance. Much stronger part than OEM plastic Will not become brittle and fatigue over time due to thermal cycling. This will prevent the part from breaking during removal and re-installation. Constructed of 4-Ply reinforced silicone for improved durability over the failure-prone OE rubber hose. Flourosilicone lined internal layer for exceptional chemical resistance. Silicone offers reduced thermal conductivity as well as improved resistance to ozone and UV degradation for improved performance and durability. Follows OEM form for perfect fitment. Utilizes OEM O-ring 11537545278 to ensure a proper seal. Replaces Genuine BMW Part Number: 11537603514
